jQuery prioritizes enforcing style over using a CSS file

I am facing an issue with a nested div functioning similar to a drop-down menu. The problem arises when I click on the #two div as I want it to disappear.

To handle this, I utilized jQuery and tried using both .hide() and .slideUp().

However, upon implementing either of these methods and then hovering over #one, #two fails to reappear again.

Upon investigation, I discovered that jQuery adds the attribute style="display:none" to div#two, which cannot be overridden by CSS.

Adding display: block !important; in the CSS doesn't work either as it prevents jQuery from hiding #two when clicked.

What is the middle ground solution for this scenario? Re-triggering the class that hides #two does not resolve the issue since the mouse is still positioned over #one.

<div id="one">
    <span>Main</span>
    <div id="two">Sub</div>
</div>

The CSS code will look like:

#one{
    position: relative;
}

#two {
    display: none;
    position: absolute;
    width: 100%;
    top: 100%;
    left: 0;
}

#one:hover #two {
    display: block;
}

Answer №1

It seems like the issue lies with how you are connecting your JavaScript actions. It's generally recommended to avoid mixing the use of .show() and .hide() with direct display manipulation in CSS. It's best to choose either JavaScript or CSS for handling visibility and stick with that approach.

Please remove the following code snippet:

#one:hover #two {
    display: block;
}

Instead, use the following JavaScript solution:

$('#one span').click(function(){
    $('#two').show();
})

$('#two').click(function(){
    $('#two').hide();
});
