I am trying to implement a drop up menu. As a starting point I am using an existing drop down menu built using HTML/CSS/jQuery based on CSS trick's Simple jQuery Dropdowns. (As I couldn't get a pure css one to work on touch devices as they relied on hover states.)
I have made a little bit of progress fiddling with ul.dropdown ul {top: -100%; } but this only moves the dropdown up one 'row', I am not convinced that's semantic css.
Any ideas how I could achieve this ?
I have made a jsfiddle of the problem here - http://jsfiddle.net/TTTb6/
Try changing this:
ul.dropdown ul {
bottom: 100%;
}
Updted jsfiddle
Instead of top, use bottom: 100%;:
ul.dropdown ul {
position: absolute;
bottom: 100%;
}

Working with a Angular js modal with a dropdown menu. The menu list is pretty long. In 70% time the menu arriving in lower direction then its ok. but approx in 30% time the dropdown menu arriving in upper direction, then some parts of my list is going hide. is there any way to make it always in lower direction???
Can you provide some code? Do you use external modules? Bootstrap maybe? I can only guess it's more like CSS issue. Try this:
.dropdown .dropdown-menu {
position: absolute;
top: 100%;
left: 0px;
}
This is an issue on Firefox and IE so far that I've tested; the problem does not exist on Chrome.
I'm including two TinyMCE editors on a page with one partially off-screen to start. When I select the color picker dropdown option from the toolbar on the first TinyMCE instance, the dropdown appears where it should. But if I scroll down and select the color picker dropdown in the second instance, that dropdown appears way below the editor and typically off the page.
You can see this in action here: http://jsfiddle.net/nm6wtca3/
Without removing the html, body CSS, what can I do to have the color picker always appear in the correct position?
I've traced the problem down to setting CSS on the html, body elements.
html, body {
width: 100%;
height: 100%;
overflow-x: hidden;
}
The dropdown div has CSS applied to it that is auto-calculated by TinyMCE. It looks something like this:
z-index: 65535;
left: 641.467px;
top: 633px;
width: 162px;
height: 105px;
How it appears in FF (sometimes way worse):
How it appears in Chrome (how it should look):
You did say you don't want to remove any CSS from the html,body, but you didn't say anything about adding to it! This solution is based on the assumption that you can add to the html,body
Solution
html, body {
width: 100%;
height: 100%;
overflow-x: hidden;
position: relative; /* Line added */
}
JSFiddle Example
I hope this helps. In all reality, you really only need to apply position: relative; to the body like so body { position: relative; }
I'm not super familiar with tinymce's colorpicker, but I can see the issue, and I can replicate it reliably: your problem occurs when you have a picker open, and then you scroll. I can replicate this in chrome too. Here's a video.
When I look at the DOM, I see that tinyMCE has created two absolute-positioned divs at the end of document.body, one for each picker. When you open one, their position is updated to reflect the location of the toolbar-button at the time you clicked it, but it never gets updated when you scroll!
So, how to solve this? Well, there are a few possibilities:
Option 1: it looks like tinyMCE provides a method to bind a control to an event (here). With this, you could bind a callback to 'scroll' that repositions the box...
Huh, now that I think of it, you could simply close any open colorpickers whenever a user scrolls ... kinda feels like a cop-out but there's no denying it has the best R.O.I. ;) We'll call that Option 2!
Option 3: depending on the implementation of the colorpicker, you may be able to override where in the DOM those divs get rendered. The API method I saw that looked the most promising is here. Once you have the div inside a relative-positioned parent, you'd also have to make the colorpicker's positioning algorithm smart enough to look in the right place for x and y offset ...when I tried this by just moving the element and mashing in some css by hand in chrome-console, the algorithm still computed x and y offsets based on doc.body, so depending on where you were scrolled at click-time, everything would be out of position
It looks like this issue might be troubling other people as well... maybe they've found a solution but haven't posted anything about it?
I hope this is enough info to get you past the problem... Let me know if you have any questions!
It looks like the problem is caused by overflow-x: hidden;
It may not be the answer you want but removing that or moving it to a page wrapper will solve your problem.
Working Example
html, body {
width: 100%;
height: 100%;
padding:0;
margin:0;
}
#pagewrapper{
overflow-x: hidden;
}
Another option would be to force repositioning on scroll, but honestly this is overkill... I strongly recommend fixing the css instead.
Another working example
$('body').scroll(posfix); // when the body scrolls
$('#mceu_10').click(posfix); // when you click the top font color button
$('#mceu_35').click(posfix); // when you click the bottom font color button
function posfix() {
setTimeout(function () { // hack way to ensure it fires after the menu is shown
$('#mceu_51').css({
top: $('#mceu_10').offset().top + $('#mceu_10').height(), // set top/left based on button's position
left: $('#mceu_10').offset().left + $('#mceu_10').width() / 2
});
$('#mceu_52').css({
top: $('#mceu_35').offset().top + $('#mceu_35').height(),
left: $('#mceu_35').offset().left + $('#mceu_35').width() / 2
});
}, 1);
}
it works on firefox, and Internet Explorer fine
just remove this css code
html, body {
width: 100%;
height: 100%;
overflow-x: hidden;
}
Please take a look at this:
html,
body {
width: auto;
height: auto;
overflow-x: hidden;
}
You can simply set body width and height to auto, then there won't be any need to use position and you don't have to remove anything. I think you do not need to use height: 100% since it will be auto-calculated by TinyMCE. i hope it helped.
Update
Look at the screen shot from chrome and its same in firefox. And i didn't remove any css but just changed..and by putting 100% in css the output will be like :-
Please check this one with auto but not 100%..thank you
I have a JQuery autocomplete search box which when displaying the search results in the dropdown window appears behind a JQuery dropdown menu directly below it (see image). I have tried increasing the z-index value of everything I can find in the CSS for the autocomplete search but it still doesn't fix the problem. What else should I be trying?
Fiddle link: http://jsfiddle.net/tonyyeb/LKDBh/18/
Thanks for everyone's contributions. I have since found a solution given to me by a forum user:
The autocomplete wrapper is being given a z-index of 1 by the jQuery library (hard-coded), >whereas the menu (via CSS) has a z-index of 100; easiest solution is to use -
.ui-autocomplete {
z-index: 100 !important;
}
I had a similar issue with a website recently and I've fixed this with the following method:
Make sure that you position both elements absolute OR relative (z-index only works when you use the 'position' css element. So you should either use position: absolute; or postion: relative;. That totally depends on your code/css. When you don't use the position element right now, you should probably use the position: relative; element since the position:absolute; element will position the referring element absolutely which will probably screw up your layout).
Then make sure you give the dropdown a z-index which is lower then the z-index for the menu.
Example
.search-dropdown{
position: relative; or position: absolute;
z-index: 1;
}
.jquery-menu{
position: relative; or position: absolute;
z-index: 2;
}
Now, you've added
position: relative;
z-index: 1;
to .ui-widget.
Remove it there and add it directly to the dropdown's css which appears when you enter something in the input field (Chrome/Firefox: Right Click on the dropdown and inspect element to see its class/ID).
Hope this helps!
A few months ago I had a similar problem, and searched the web.
The solution was in the CSS styling.
I added an inline class (ui-front) to the element that holds the autocomplete input element.
Not sure it will solve your problem, but it's an easy experiment.
Best of luck!
Question has been posted long time ago. Still, i also have a solution that works and not listed till now .
just add this on top of your page and problem should be solved.
.pac-container { position: absolute; cursor: default;z-index:3000 !important;}
I am create a WYSIWYG editor in my free time. I decided I wanted to use the drop down to allow myself to select formatting. The problem is when I add a dropdown it isnt under the button but at the beginning of the the button container.
here is an image to show what I mean.
The first button looks active because the text is aligned left... Sorry I tried to find a way to fix that but the dropdown is from the last button.
My question is, is there a way to align a Twitter Bootstrap Dropdown, with the button it is supposed to be on or atleast make the dropdown with the width of the button container.
Yes. You can just add a rule, left: auto; right: 0; for the <ul> coming there, by targeting or giving a class, say .right-menu, this way:
.right-menu, .dropdown-menu.right-menu {left: auto; right: 0;}
A working demo of the same would be in jsFiddle.
It's not a bad thing to use .pull-right on the .dropdown-menu to make it stick to the right of the container.
As seen in the source, this class is meant to do that :
// Aligns the dropdown menu to right
&.pull-right {
right: 0;
left: auto;
}
If you prefer to make it as big as the container, you can try applying this to your menu :
.dropdown-menu {
min-width: 100%;
}
You should keep .pull-right in case you have bigger menus.

I am trying to figure out how to create an image gallery like the one illustrated below so I can place it onto my website. I am wondering if anyone can point me in the right direction for a tutorial? I have found a lot of nice galleries that will display my images, but none of them displays the images like in the filmstrip style I am after.
Requirements of gallery:
When clicking on the arrows, the gallery strip will either shift
left/right by one picture
Hovering over the image will darken the image, and display some
caption about the image
I just answered a question where someone was using carouFredSel. This jQuery plugin looks like it would work pretty well, though I do not think it has the built-in hover effect. To be honest though, that is the easier part.
The trick is to make the width slightly larger than the images to show, which leads to the partial images on each side.
Here is a jsfiddle to illustrate.
UPDATE:
The OP asked if the page nav links could be repositioned. I modified the jsfiddle to work this way. The additions were as follows:
.list_carousel {
position: relative;
}
#prev2 {
position: absolute;
top: 35px;
left: 0;
}
#next2 {
position: absolute;
top: 35px;
right: 0;
}
If you have a relatively positioned container element, you can absolutely position child elements. I added relative positioning to the list_carousel container, then I could absolutely position the nav arrows within the container. Change the top value to position vertically, and left/right to position horizontally.
I also removed the pager all together, as it was not a requirement based on the original example. If you change the page arrows to images it is pretty much what you want.
MORE UPDATES
I decided to take it one step further and make the hover effect work more like the example. See the new jsfiddle. The changes are:
Added span wrappers around all text within list items
Added $(".list_carousel li span").hide(); to hide all the spans
Modified hover event to toggle spans
I also added some CSS to position the span text:
.list_carousel li {
position: relative;
}
.list_carousel li span {
position: absolute;
bottom: 0;
display: block;
text-align: center;
width: 100%;
}
FINAL UPDATE (I PROMISE!)
I decided to go all in and add the transparency layer too: jsfiddle
Hover modifications:
$(this).prepend($("<div class='hover-transparency'></div>")); and $(this).find("div:first").remove(); to add/remove transparency layer on hover in/out.
CSS modifications:
.hover-transparency {
position: absolute;
top: 0;
right: 0;
bottom: 0;
left: 0;
background-color: rgba(0, 0, 0, 0.60);
}
These style the transparency layer. Change to suit your taste.
Something like jCarousel should do the trick. Once you have the carousel functionality in place, you can add in the hover affect via CSS and a span that contains the caption.
I was just looking at ContentFlow Plugin which is JavaScript based.
They include a separate library of additional plugin you can use that takes care of your Slideshow requirements, in particularity this one HERE. When you use the mousewheel over the 3 images, it scrolls by 1. That said, you can mod the plugin to do the same when the arrow buttons are clicked.
Sample plugin markup looks like:
{
shownItems: 3, //number of visible items
showCaption: true // show item caption
width: 100, // relative item width
height: 100, // relative item height
space: 0.4 // relative item spacing
}
To address that the captions should be visible only on mouse hover, I would set showCaption to always be true along with using a jQuery .hover(); Event Listener that will use .show(); and .hide(); on the caption Class Name .caption when required. Also, using jQuery to set the opacity can be done within the .hover(); event too.
The latest version of ContentFlow v1.0.2 supports multiple instances on the same webpage if that's ever required.
