What causes the dropdown menu to be obscured by the jQuery button?

How can I prevent the menu drop down from overlapping the jQuery button?

div.menu ul li a, div.menu ul li a:visited
{
    background-color: #465c71;
    border: 1px #4e667d solid;
    color: #dde4ec;
    display: block;
    line-height: 1.35em;
    padding: 4px 20px;
    text-decoration: none;
    white-space: nowrap;
    position: relative;
    z-index: 9999;
}

Answer №1

I encountered a similar issue and was able to identify both the problem and solution.

Issue: The button appeared after the menu due to being wrapped in additional elements by jquery-ui, causing its z-index to increase.

Resolution: To fix this, increasing the z-index of the menu is recommended over decreasing the z-index of multiple buttons. However, it's important to note that

"z-index only applies to positioned elements (position:absolute, position:relative, or position:fixed)"

Therefore, our menu must also be positioned. Below is the code snippet I used:

<div style="position:relative;z-index:99"> INSERT MENU CODE HERE </div>

Answer №2

Don't forget to try this out as well

section.sidebar 
{

   position: fixed;
   top: 0;
   z-index : 9999;
}

It appears that you are only adjusting the z-index for active elements. Have you considered how inactive elements will be affected?

Answer №3

My experience with a jquery combobox plugin revealed that the full dropdown was not displaying due to insufficient space in the parent div. After extensive investigation and adjustments to parameters like z-index, I eventually discovered that changing the parent div's overflow to "visible" resolved the issue. This solution could potentially assist others facing similar challenges.

Answer №4

To ensure proper layering, it is essential to confirm that the z-index value of your list is greater than that of your button as demonstrated below:

div.menu ul li {
 z-index:999;
}

.yourbutton {
 z-index: 1;
}

Please share your HTML code for further assistance.
