jquery slide down effect - without moving inner contents - javascript

I am trying to achieve a simple slide up/down effect similar to the 'more' link on www.bbc.co.uk
YOu can see that the inner contents do not move up and down, instead it is like a screen is being pulled over them.
Using jquery slideUp slideDown does not achieve this, instead the whole div is moved up and down so the text looks like it moves.
How can a similar effect be achieved using jquery?

Just put your sliding div between the menu and the content:
<div id="menu">Menu example. Click here!</div>
<div id="slide">Whoa! sliding div<br>See how it moves the content down</div>
<div>Content here</div>
See fiddle: http://jsfiddle.net/2hZme/1/

slideUp/slideDown uses the top position when it animates, when you want to use the height. So I'd suggest to animate it manually:
// Initial variables
var panel = $('#panel');
var panelHeight = panel.height();
// Set the height to 0
panel.height('0px');
// Animate it to its initial size
$('a').click(function() {
$('#panel').animate({'height' : panelHeight});
});
... and of course the CSS:
#panel {
overflow: hidden;
height: 300px; /* or whatever */
}

Hiding a <div> and showing a new one in the same spot?

Lets say I have 2 divs, one is hidden, the other is showing. When a button is clicked, I want to use the jQuery fade effect to fade out one div and fade in the hidden div.
So -
<div id="part1">Hello</div>
<div id="part2" style="display: none">Hello2!</div>
<button id="btn1">Click here!</button>
and the JS -
$("#btn1").on("click", function(){
$("#part1").fadeToggle();
$("#part2").fadeToggle();
});
Now, this works, but as you can imagine what happens is that it first hides the 1st div, then shows the second div, and then immediately takes the second div up to the place where the previous div was located.
What can I do about this? I want them to stay in the same position (something like they have here http://kenwheeler.github.io/slick/ in their fade demo.)
Thanks!
You can do it with jQuery. Fade out the first div and fade in the second one in the callback. Like this: http://jsfiddle.net/D2Cw9/
$(".one").fadeOut(500, function() {
$(".two").fadeIn(500, function() {
});
});
One solution would be using absolute positioning on both divs relative to their container.
#parts-container {
position: relative;
}
#part1, #part2 {
position: absolute;
left: 0;
top: 0;
}
Use css position absolute to set them to the same position.
At the time of writing, you have 4 answers that all seem to be correct solutions using CSS positioning. I noticed you have jQuery as a tag, so I thought I'd offer up a different solution.
Have you thought about not actually hiding the div, and replacing it with the other? For example, you could change the CSS class of the div with jQuery:
$('#part1').fadeOut(300, function() {
$('#part1').addClass('part2');
$('#part1').innerHTML('Hello2!');
$('#part1').fadeIn(300, function(){});
});
Of course you should use a synchronous fade to make sure the class change happens while the div is hidden.
It seems that a lot of people answered this question correctly. I would like to add that you can also keep the div and just set the css opacity to 0 using the jQuery UI color animation.
I believe this is yet another option.
Try adding position absolute to both of them and wrapping them in a relative div

jquery slide effect, hide one div and show another

I have this JSFIDDLE setup demonstrating my problem, I'm sure that it's a simple fix.
I am trying to slide out the blue div to the left, while sliding in the red div from the right, at the same time. The sliding animations are working how I want them to, however when the red div is sliding in it appears below the blue div. How can I get it to be positioned to the right of the blue div instead of appearing beneath it during the animation?
code:
$("#slide2").on('click', function(){
$( "#blueDiv" ).effect( "slide", hideoptions, 1000);
$( "#redDiv" ).effect( "slide", showoptions, 1000);
});
You can use position: absolute to take them out of the flow and place them beside each other:
div > div
{
position: absolute;
}
If you want to make it more specific to this div, you can use a specific selector:
#contentWrapper div
{
position: absolute;
}
JSFiddle
http://jsfiddle.net/ggfA6/12
position: absolute
Both elements need to be absolutely positioned so that they don't occupy space in the flow.

jQuery - slide down panel

I want to create a website where the user has to enter soma data. To make this as easy as possibble, i just show the main input elements and let a helper panel slide down if needed. As possible, these panels should be draggable (i am looking for javascript for that in the moment). My main problem is that when the panel slides down, the content at the top is shown first, but i want to slide down like shown below:
Is there any way to make this?
Thanks in advance.
Look at this JSFiddle.
This should show the principle to achieve this effect. You need a container div with overflow: hidden; and a child positioned to the bottom of the container div, then you can change the height of the container with jQuery to show/hide the content.
Also, to make the panels draggable, jQuery UI has a great function called draggable which works great. Give it a try.
Quick access: Fiddle: http://jsfiddle.net/VuPyL/1/ (updated) , BTW: I made it toggle-like.
Generally it seems to be only solve-able with animate,
if you dont want to have any wrapper element you would really like to use DOM's native property "scrollHeight" - that allows you to scroll always to bottom, in combination with a height toggle, it does exactly what you need.
Overflow: hidden dont have to be in the CSS - jQuery is adding it itself while toggling height.
This solution may seem a bit longer, but is more clear in what is actually happening :) :
HTML
<div id="helper-panel">
Here's
<br />
My
<br />
Content
</div>
<button id="show-helper">Show/hide Helper Panel</button>
CSS
#helper-panel{
height: 70px;
width: 375px;
position: relative;
overflow: hidden; /*optional - jQuery is adding it*/
display: none;
}
JS/jQuery
$('#show-helper').click(function(){
var $helper = $('#helper-panel');
$helper.animate({
height: "toggle"
},{
duration: 800,
progress: function(){
$helper.scrollTop( $helper[0].scrollHeight );
}
});
});
As suggested by #Andrew Pope to have item draggable/droppable it is best to use jQuery UI's draggables&droppables.
Also check sortable if you just want to change the order of the helper-menu items using drag&drop ;)
jQuery UI is not a standard part of jQuery - so dont forget to include it.
When using these it is good to wrap each draggable element. So the HTML would be:
<div id="helper-panel">
<div>Here's</div>
<div>My</div>
<div>Content</div>
</div>
And the jQuery (with jQuery UI):
$('#helper-panel').sortable() //make the items inside #helper-panel sortable
.disableSelection() //when sorting, you dont want selecting
.css('cursor','default'); //looks better with default cursor

How to move an entire div element up x pixels?

I want to reposition an entire div and its contents up about 10-15 pixels.
How can I do this?
Note: this is slider element, so when I click a button the slider slides down. Once it is finished I want to reposition it up about 15 pixels.
$('#div_id').css({marginTop: '-=15px'});
This will alter the css for the element with the id "div_id"
To get the effect you want I recommend adding the code above to a callback function in your animation (that way the div will be moved up after the animation is complete):
$('#div_id').animate({...}, function () {
$('#div_id').css({marginTop: '-=15px'});
});
And of course you could animate the change in margin like so:
$('#div_id').animate({marginTop: '-=15px'});
Here are the docs for .css() in jQuery: http://api.jquery.com/css/
And here are the docs for .animate() in jQuery: http://api.jquery.com/animate/
$('div').css({
position: 'relative',
top: '-15px'
});
In css add this to the element:
margin-top: -15px; /*for exact positioning */
margin-top: -5%; /* for relative positioning */
you can use either one to position accordingly.
you can also do this
margin-top:-30px;
min-height:40px;
this "help" to stop the div yanking everything up a bit.
