Change height of child element on button/link press using ::before - javascript

I've got an Org Chart that will run on mobile devices nearly completely different from how it runs on desktop. Everything is as it should be with one minor problem. My Org Chart features the ability to click a person which then slides an accordion down to provide more information about that particular person along with contact information. This feature is great on desktop but when it runs to mobile, my connectors are based on fixed values in the CSS. I need the ::before height to be changed when the accordion is extended to counter this. I've provided photos below for further clarification.

Now my main concern is that I've put myself in a position where I'll have to write totally different functions for each element in order for that particular element to connect.
Here's how my HTML is laid out:
<ul>
<li class="director">
<div id="ss_menu">
<a href="javascript:void(0);" class="ss_button">
<span class="title">Director </span><br/>
<span class="sm-hide">Name of Person</span>
</a>
<div class="ss_content">
<img src="img/person.jpg"
width="70px"
style="border: 1px solid #000;"/><br/>
Telephone: 555-555-5555<br/>
Email: emailaddress#email.com<br/>
Room: A123<br/>
Mail Stop: A123
</div>
</div>
<ul>
<li>
<div id="ss_menu">
<a href="javascript:void(0);" class="ss_button">
<span class="title">Assistant to the Director </span><br/>
<span class="sm-hide">Name of Person</span>
</a>
<div class="ss_content">
<img src="img/person.jpg"
width="70px"
style="border: 1px solid #000;"/><br/>
Telephone: 555-555-5556<br/>
Email: emailaddress#email.com<br/>
Room: A124<br/>
Mail Stop: A124
</div>
</div>
<ul>
<! -- THE CODE CONTINUES FOR A WHILE BUT IS LAID OUT THE SAME WAY -->
And then here is the general layout of the vertical lines using the ::before keyword:
.director::before {
content: "";
border-left: 1px solid #ccc;
position: absolute;
height: 165px;
margin-left: -30px;
z-index: -1;
}
.deputydirector::before {
content: "";
border-left: 1px solid #ccc;
position: absolute;
height: 1442px;
margin-left: -30px;
z-index: -1;
}
I'm essentially trying to increase the height of the vertical lines by the amount that the accordion opens.
Lastly here is the jQuery code I'm using for the accordion which I'd like to use as a catch-all for managing my vertical lines as well.
jQuery(function() {
jQuery('.ss_button').on('click',function() {
jQuery('.ss_content').slideUp('fast');
jQuery(this).next('.ss_content').slideDown('fast');
});
});

What would be the best way to make a sort of drop-down-more-info div?

I have 4 divs with a more-info button on the bottom of each, like so:
http://codepen.io/anon/pen/VpVbPq
And when a user presses ' more info ' I would like for it to extend to the bottom and show extra info, obviously.
The problem is under the more-info div, text is seen, but what if I want to hide whats under it, even if its opacity is 0.6 ?
I thought it would've been the best if I draw what I need, so here:
Codepen code below:
html
<body>
<div class="wrapper">
<div class="info">
<p>
dummy text
</p>
<div class="more-info">more info</div>
</div>
<div class="info"><div class="more-info">more info</div></div>
<div class="info"><div class="more-info">more info</div></div>
<div class="info"><div class="more-info">more info</div></div>
</div>
</body>
css
.wrapper {
width: 1045px;
margin: 0 auto;
}
.info {
width: 500px; height: 200px;
background-color: #1A5AB6;
display: inline-block;
margin: 10px;
position: relative;
font-size: 20px;
overflow: hidden;
}
.more-info {
width: 100%; height: 40px;
background-color: #0C1B44;
bottom: 0; left: 0;
display: inline-block;
position: absolute;
font-size: 20px;
color: white;
line-height: 35px;
text-align: center;
opacity: 0.6;
}
.more-info:hover {background-color: #010716;}
In order to have the text expand, you can use a little jQuery to set the height to automatically adapt to however much text there is, and hide the 'more info' button entirely:
$(".more-info").on("click", function() {
$(this).css("opacity", "0");
$(this).parent().css("height", "auto");
});
With regards to not having the text visible behind the 'more info' button, you would need to set the opacity to 1:
.more-info {
opacity: 1;
}
This naturally distorts the colour a little, but you can always change the background colour and hover colour to cover this.
I've created an updated pen showcasing this here.
Hope this helps! :)
change your class selector definition as shown below:
.more-info {
width: 100%; height: 20%;
background-color: #0C1B44;
font-size: 20px;
color: white;
display: block;
text-align: center;
opacity: 0.6;
}
Then add this css for your paragraph element:
p {
height: 75%;
overflow: hidden;
margin: 5px;
}
Your question: "what would be the best way to make a sort of drop-down-more-info div?"
There is a built in function in Boot Strap that allows you to use a "data" class that does all the crunching for you. Just call on their css and js files externally or host on your server. Familiarize yourself with their data classes and call on their css/js classes to simplify previously arduous coding, like revealing a hidden DIV on click!
Note the data-toggle="collapse" and data-target="#more_info" lines in my div that holds the span tag that is the control for revealing the hidden <div id="more_info">:
`<div data-toggle="collapse" data-target="#more_info"><span class="glyphicon glyphicon-search"></span> <span title="Click for more info">more info</span></div>`
Then note the class in my hidden div. Note the id of the hidden div and the data-target #more_info. This can be used for classes as well, ie: .more_info. Everything is explained in more detail at bootstrap Github or their official site: http://getbootstrap.com/

or add three divs floating perfectly without all the css, each with drop downs more info.

trying to collapse text [duplicate]

I have created a list on my site. This list is created by a foreach loop that builds with information from my database. Each item is a container with different sections, so this is not a list like 1, 2, 3... etc. I am listing repeating sections with information. In each section, there is a subsection. The general build is as follows:
<div>
<fieldset class="majorpoints" onclick="majorpointsexpand($(this).find('legend').innerHTML)">
<legend class="majorpointslegend">Expand</legend>
<div style="display:none" >
<ul>
<li></li>
<li></li>
</ul>
</div>
</div>
So, I am trying to call a function with onclick="majorpointsexpand($(this).find('legend').innerHTML)"
The div I am trying to manipulate is style="display:none" by default, and I want to use javascript to make it visible on click.
The "$(this).find('legend').innerHTML" is attempting to pass, in this case, "Expand" as an argument in the function.
Here is the javascript:
function majorpointsexpand(expand)
{
if (expand == "Expand")
{
document.write.$(this).find('div').style = "display:inherit";
document.write.$(this).find('legend').innerHTML = "Collapse";
}
else
{
document.write.$(this).find('div').style = "display:none";
document.write.$(this).find('legend').innerHTML = "Expand";
}
}
I am almost 100% sure my problem is syntax, and I don't have much of a grasp on how javascript works.
I do have jQuery linked to the document with:
<script src="http://code.jquery.com/jquery-1.9.1.min.js"></script>
In the <head></head> section.
Okay, so you've got two options here :
Use jQuery UI's accordion - its nice, easy and fast. See more info here
Or, if you still wanna do this by yourself, you could remove the fieldset (its not semantically right to use it for this anyway) and create a structure by yourself.
Here's how you do that. Create a HTML structure like this :
<div class="container">
<div class="header"><span>Expand</span>
</div>
<div class="content">
<ul>
<li>This is just some random content.</li>
<li>This is just some random content.</li>
<li>This is just some random content.</li>
<li>This is just some random content.</li>
</ul>
</div>
</div>
With this CSS: (This is to hide the .content stuff when the page loads.
.container .content {
display: none;
padding : 5px;
}
Then, using jQuery, write a click event for the header.
$(".header").click(function () {
$header = $(this);
//getting the next element
$content = $header.next();
//open up the content needed - toggle the slide- if visible, slide up, if not slidedown.
$content.slideToggle(500, function () {
//execute this after slideToggle is done
//change text of header based on visibility of content div
$header.text(function () {
//change text based on condition
return $content.is(":visible") ? "Collapse" : "Expand";
});
});
});
Here's a demo : http://jsfiddle.net/hungerpain/eK8X5/7/
how about:
jQuery:
$('.majorpoints').click(function(){
$(this).find('.hider').toggle();
});
HTML
<div>
<fieldset class="majorpoints">
<legend class="majorpointslegend">Expand</legend>
<div class="hider" style="display:none" >
<ul>
<li>cccc</li>
<li></li>
</ul>
</div>
</div>
Fiddle
This way you are binding the click event to the .majorpoints class an you don't have to write it in the HTML each time.
You might want to give a look at this simple Javascript method to be invoked when clicking on a link to make a panel/div expande or collapse.
<script language="javascript">
function toggle(elementId) {
var ele = document.getElementById(elementId);
if(ele.style.display == "block") {
ele.style.display = "none";
}
else {
ele.style.display = "block";
}
}
</script>
You can pass the div ID and it will toggle between display 'none' or 'block'.
Original source on snip2code - How to collapse a div in html
So, first of all, your Javascript isn't even using jQuery. There are a couple ways to do this. For example:
First way, using the jQuery toggle method:
<div class="expandContent">
Click Here to Display More Content
</div>
<div class="showMe" style="display:none">
This content was hidden, but now shows up
</div>
<script>
$('.expandContent').click(function(){
$('.showMe').toggle();
});
</script>
jsFiddle: http://jsfiddle.net/pM3DF/
Another way is simply to use the jQuery show method:
<div class="expandContent">
Click Here to Display More Content
</div>
<div class="showMe" style="display:none">
This content was hidden, but now shows up
</div>
<script>
$('.expandContent').click(function(){
$('.showMe').show();
});
</script>
jsFiddle: http://jsfiddle.net/Q2wfM/
Yet a third way is to use the slideToggle method of jQuery which allows for some effects. Such as $('#showMe').slideToggle('slow'); which will slowly display the hidden div.
Many problems here
I've set up a fiddle that works for you: http://jsfiddle.net/w9kSU/
$('.majorpointslegend').click(function(){
if($(this).text()=='Expand'){
$('#mylist').show();
$(this).text('Colapse');
}else{
$('#mylist').hide();
$(this).text('Expand');
}
});
try jquery,
<div>
<a href="#" class="majorpoints" onclick="majorpointsexpand(" + $('.majorpointslegend').html() + ")"/>
<legend class="majorpointslegend">Expand</legend>
<div id="data" style="display:none" >
<ul>
<li></li>
<li></li>
</ul>
</div>
</div>
function majorpointsexpand(expand)
{
if (expand == "Expand")
{
$('#data').css("display","inherit");
$(".majorpointslegend").html("Collapse");
}
else
{
$('#data').css("display","none");
$(".majorpointslegend").html("Expand");
}
}
Here there is my example of animation a staff list with expand a description.

Fiddle
Take a look at toggle() jQuery function :
http://api.jquery.com/toggle/
Also, innerHTML jQuery Function is .html().
Since you have jQuery on the page, you can remove that onclick attribute and the majorpointsexpand function. Add the following script to the bottom of you page or, preferably, to an external .js file:
$(function(){
$('.majorpointslegend').click(function(){
$(this).next().toggle().text( $(this).is(':visible')?'Collapse':'Expand' );
});
});
This solutionshould work with your HTML as is but it isn't really a very robust answer. If you change your fieldset layout, it could break it. I'd suggest that you put a class attribute in that hidden div, like class="majorpointsdetail" and use this code instead:
$(function(){
$('.majorpoints').on('click', '.majorpointslegend', function(event){
$(event.currentTarget).find('.majorpointsdetail').toggle();
$(this).text( $(this).is(':visible')?'Collapse':'Expand' );
});
});
Obs: there's no closing </fieldset> tag in your question so I'm assuming the hidden div is inside the fieldset.
If you used the data-role collapsible e.g.
<div id="selector" data-role="collapsible" data-collapsed="true">
html......
</div>
then it will close the the expanded div
$("#selector").collapsible().collapsible("collapse");
Pure javascript allowing only one expanded div at a time. It allows multi-level sub-expanders. The html only need the expanders contents. The javascript will create the expanders headers with the titles form the content data attribute and a svg arrow.

Here are the available options to configure your widget:
{
speed: 100,
collapsedHeight: 200,
heightMargin: 16,
moreLink: 'Read More',
lessLink: 'Close',
embedCSS: true,
blockCSS: 'display: block; width: 100%;',
startOpen: false,
// callbacks
blockProcessed: function() {},
beforeToggle: function() {},
afterToggle: function() {}
},
Use can use it like:
$('article').readmore({
collapsedHeight: 100,
moreLink: 'Continue reading...',
});
I hope it helps.

How to represent a breadcrumb child?

I represent the breadcrumb in a table as follow:
<ol class="breadcrumb" data-sly-use.breadcrumb="myModel.js">
<output data-sly-unwrap data-sly-list="${breadcrumb}">
<li itemscope itemtype="http://data-vocabulary.org/Breadcrumb">
<a href="${item.href}" itemprop="url">
<span itemprop="title">${item.label}</span>
</a>
</li>
</output>
</ol>
How to represent the breadcrumb child in this structure?
It seems like you are using apache sling, which I haven't used myself, but for setting up a simple breadcrumb, it can be done just with CSS. Here is one which I set up using display: inline on the the li.
jsfiddle
I'm sure you could use some pretty nice styling on it, but this is a simple example using a triangle for the arrows on the breadcrumb.
html
<div id="menu">
<ul>
<li>
<a href="#" itemprop="url">
<span itemprop="title">item 1</span>
</a>
</li>
<div class="arrow-right"></div>
<li>
<a href="#" itemprop="url">
<span itemprop="title">item 2</span>
</a>
</li>
</ul>
</div>
css
.arrow-right {
width: 0;
height: 0;
border-top: 0.5em solid transparent;
border-bottom: 0.5em solid transparent;
border-left: 0.5em solid black;
display: inline-block;
}
#menu ul{
list-style: none;
}
#menu li{
display: inline;
}
I'm not entirely sure what your question is. What do you mean by "breadcrumb child"? In the Sightly example you give each item is one of the elements of the breadcrumb, so that is what I would assume the "child" is, but that doesn't seem to be what you mean.
If the question is about what myModel.js might look like, it would simply have to implement the javascript Use API and return a list of objects. For example
"use strict";
use(function () {
var crumbs= [];
crumbs.push({href: '/home/path', label: 'Home'});
crumbs.push({href: '/section/path', label: 'Section'});
return crumbs;
});
Rather than hard coding the crumbs you can use the objects that Sling gives you to get the parents of the current page, but this works as a simple example.
note: At this point you should probably use the Java API, rather than the javascript API for production code. See the comparison chart from Adobe's Sightly Intro

adding an active state to menu link with javascript

I am trying to add an active state to my fadetoggle menu.
When the user clicks on one of the menu options, the menu fades in and with it an arrow appears under the active menu item. The menu fades in and out when the user clicks on it, what I cant get right is the active state. I have seen a couple of examples online. I want simple to understand code and I have come up with the following javascript code:
$(function() {
$('.menu-item-recovery a').live('click', function(event) {
$('.recovery-bg').show();
$('.recovery-bg').addClass('active');
return false;
});
});
When the user clicks on any of the links below:
<!--Logo & Second Nav-->
<div class="container hidden-phone">
<div class="row">
<div class="span9 second-nav">
<div class="menu-wrapper">
<div class="menu-item-recovery recovery trigger" data-target=".recovery-bg">
Recovery
</div>
<div class="menu-item-forensic trigger" data-target=".forensic-bg">
Forensics
</div>
<div class="menu-item-erasure trigger" data-target=".erasure-bg">
Erasure
</div>
<div class="menu-item-training trigger" data-target=".training-bg">
Training
</div>
<div class="menu-item-products trigger" data-target=".product-bg">
Products
</div>
</div>
</div>
</div>
</div>
<!--/Logo & Second Nav-->
The following menu fades in and an active state needs to be added to it:
<!--Expanding Recovery Menu-->
<div class="recovery-bg arrow_box_recovery toggle hidden-phone">
<div class="container expand">
<div class="row">
<div class="span12">
<div class="menu-item menu-item-1 menu-first-rec">
<a href="http://dev.disklabs.com/html/data-recovery.html">
<p>Data <br/> Recovery</p></a>
</div>
<div class="menu-item menu-item-2">
<a href="">
<p>Raid <br/> Recovery</p></a>
</div>
<div class="menu-item menu-item-3">
<a href="">
<p>Forensic <br/> Data Recovery</p></a>
</div>
<div class="menu-item menu-item-4">
<a href="">
<p>Tape <br/> Recovery</p></a>
</div>
</div>
</div>
</div>
</div>
<!--/Expanding Recovery Menu-->
css for the active state, not sure where I need to put it:
.active {
width: 40px;
height: 20px;
background: url(../img/menu-arrow-recovery.png) no-repeat;
}
I ended up using the cssarrowplease code I found through the stackoverflow forums. I have added a link to it cssarrowplease Its a great tool and I customised it a little because the site is responsive I changed the css so that I could add a different active arrow for every dropdown arrow. Here is the code I ended up with to achieve this.
/*------------------------------------
/ Recovery Navigation Arrow
/-----------------------------------*/
.arrow_box_recovery {
position: relative;
background: #05f397;
/*border: 4px solid $recovery;*/
}
.arrow_box_recovery:after {
content: url("http://dev.disklabs.com/html/assets/img/menu-arrow-recovery.png") no-repeat;
height: 20px;
width: 40px;
position: absolute;
top: -13%;
margin-left: -80px;
bottom: 100%;
border: solid transparent;
height: 0;
width: 0;
position: absolute;
pointer-events: none;
}
.arrow_box_recovery:after {
border-color: rgba(5, 243, 151, 0);
border-bottom-color: #05f397;
}
.arrow_box_recovery:before {
border-color: rgba(5, 243, 151, 0);
border-bottom-color: #05f397;
}
Here is a link to my fiddle gives an example of what I wanted to achieve.

Hopefully it might help someone else looking to achieve the same thing.

How to increase the height of my dropdown?

I have a dropdown in HTML. When I hover on it, it expands. I added a new entry in the dropdown, and when I hover on it, I want my new entry visible completely (I added Comp3 in dropdown. I can see the upper part of it, but not completely Comp3). I tried various things like giving height to divs, increasing the height of the component in css, but nothing helped. Viewing the source code of that in the browser, this is the small code snippet of that particular dropdown:
<div class="optionsDropDown">
<p class="optionsDropDown collapseTrigger" id="userMenu">
Hello<em> User </em><span class="closed"></span>
</p>
<ul class="optionsDropDown collapseContent closed" name="userMenu">
<li>
<a class="optionsDropDown" href="javascript:showHelp();">
<span id="0">Comp1</span>
</a>
</li>
<li>
<a class="optionsDropDown" href="myAction.do?actionCode=3&page=controlPanel" target="view">
<span id="1">Comp3</span>
</a>
</li>
</ul>
</div>
Below is the javascript function that expands the dropdown:
$.fn.openMenu = function(menuContent){
$(menuContent).slideDown(200,function() {
$(menuContent).children().fadeTo('fast',1);
});
$('span', this).removeClass('closed');
};
And here is the dropdown class:
div.optionsDropDown {
float: right;
font-size: 11px;
height: 25px;
margin: 12px 32px 0 0;
position: absolute;
top: 0px;
right: 10px;
width: 120px;
z-index: 10000;
}
Please let me know if somehow height can be increased. Thanks in advance.
I believe your <div> and <ul> heights needs to be set to auto and the heights of each <li> needs to be adjusted.
Often times CSS becomes the practice of hit or miss when dealing with issues like these. First set everything to auto then systematically experiment with every permutation.
Good luck!
