Setting the z-index for Bootstrap dropdown menus on containers that are generated dynamically

When using the Bootstrap 3 dropdown-menu within a dynamically generated container, I am encountering an issue where the dropdown-menu appears behind the newly created elements. Please refer to the image for visual clarification.

The container item has position: relative; z-index: 1; set, while the dropdown-menu has 

position: absolute; z-index: 10000;
.

I have also experimented with setting the z-index of btn-group higher but it did not resolve the problem.

You can view a working example on this fiddle link: http://jsfiddle.net/sGem8/

Answer №1

No need to include the z-index property. Just take it out and everything should function correctly.
For example:

#container > li {
  display: block;
  border-radius: 3px;
  position: relative;
  padding: 15px;
  background: #ecf0f1;
  margin-bottom: 15px;
}

Answer №2

Dealing with a similar issue, I encountered the following solution. Within the main container holding all navigation items, I designated each outermost div item with position: relative. Only the dropdown menu was set to position: absolute.

To ensure the dropdown displays above all other elements, simply include:

.dropdown{
position: absolute;
z-index : 999; //a high numerical value
}

For the rest of the items within the container, assign:

.outer-divs{
position: relative;  
z-index: 1; //a low numerical value
}

If the dropdown behavior is still not as expected, consider setting the triggering div item to:

.dropdown-container{
position: static;
}

Many individuals may find this last technique to be particularly beneficial. I trust this information proves useful.

Update the CSS code in your style sheet as shown below:

#wrapper .list-item {
 display: inline-block;
 border-radius: 5px;
 position: absolute;
 /* z-index: 1; */
 padding: 20px;
 background-color: #f7f8fa;
 margin-bottom: 20px;
}
