Expanding upon the initial instance, the parent div effortlessly widens without any visual effects as the child element is revealed or concealed

Experiencing an issue where the div element opens and closes smoothly with jQuery animation, but its parent does not. As a result, the entire page content appears jerky.

Here is a demo: http://jsfiddle.net/neDZP/7/

HTML:

<div id="A_to_Z_top">     
    <div class="section clearfix">
        <div class="region region-a-to-z-top">
            <div class="block block-block contextual-links-region" id="block-block-48">
                <h2>INDEX A-Z</h2>
                <div class="content" style="display: block;">
                    <div id="atozSlide">
                        <ul>
                            <li><a href="#">A</a></li>
                            <li><a href="#">B</a></li>
                            ... // List of letters continues
                        </ul>
                    </div>  
                </div>
            </div>
        </div>
    </div>
</div>
<p>This paragraph should slide down smoothly.</p>

Javascript:

$(function() {
  // slide effect for showing and hiding A-Z header block    
  $('#block-block-48 .content').hide();
  $('#block-block-48 h2').click(function(){ 
      var effect = 'slide';
      var options = { direction: 'up' };
      var duration = 300;
      $("#block-block-48 .content").stop().toggle(effect, options, duration);
  });
});

CSS:

#block-block-48 {
  background: #ff0000;
}

#block-block-48 h2 {
   background:  #035d8e;
   color: #ffffff;
   cursor: pointer;
   font-family: sans-serif;
   font-size: 16px;
   margin: 0;
   padding: 6px 15px 6px 0;
   text-align: right;
   text-decoration: none;
}

... // CSS styles continue

Answer №1

To start, remove display:block from the div.content selector.

Next, insert the following CSS code:

#block-block-48 > .content {
    display:none;
}

Then update the JavaScript as shown below:

$(function() {
    // Implement slide effect for displaying and hiding A-Z header block
    $('#block-block-48 h2').click(function(){
        $(this).next().slideToggle();
    });
});

This solution should resolve the issue!

Please confirm if this animation meets your requirements. If not, I can propose alternative solutions.

Here is a reference Fiddle.

Answer №2

Implement slideToggle functionality by using the following code snippet: http://jsfiddle.net/alex8rxm/dpPL9/21/

Javascript Code:

$(function() {
    // Toggle effect to show and hide content block 
    $('#block-block-48 > .content').hide();
    $('#block-block-48 h2').click(function(){ 
        var options = { direction: 'up' };
        var duration = 300;
        $("#block-block-48 > .content").stop().slideToggle( options, duration);
    });
});

Answer №3

Simplify your jQuery function for efficiency, avoiding unnecessary CSS adjustments.

Replace the following line with:

 $("#block-block-48 > .content").stop().toggle(effect, options, duration);

with this line:

$("#block-block-48 > .content").slideToggle();

JSFIDDLE

Answer №4

To view the code in action, you can check out this jsfiddle link and make edits to the CSS like so:

#block-block-48 {
}
#block-block-48 .content {
    margin: 0;
    text-align: right;
    background: none repeat scroll 0 0 #ff0000;
}

The issue here is that the background color is applied to #block-block-48, whereas the sliding element is actually #block-block-48 .content.

Answer №5

Implement this code snippet into your function.

 $(function() {
    // Utilize slide effect to show and hide the A-Z header block    
    $('#block-block-48 > .content').hide();
    $('#block-block-48 h2').click(function(){ 

   $("#abovediv").toggle("slow");
    });

  });

The ID "abovediv" corresponds to the following element.

<h2>INDEX A-Z</h2>
<div id = "abovediv" class="content" style="display: block;">
<div id="atozSlide">

Answer №6

Check out this snippet of code:

<script>
$(document).ready(function() {
  $('#block-block-32 > .content').hide();
  $('#block-block-32 h3').click(function(){ 
    var _head = $(this);
    var _body = _head.next();
    if(_body.is(':visible'))
    {
      _body.slideUp();
    }
    else
    {
      _body.slideDown();
     }
   });
 });
</script>
