How to Change the Background Color of Select List Options on Hover?

Styling Select List Option Background Color on Hover

In HTML, the default background color of select list options remains unchanged on hover. However, some users may desire a customized background color change to enhance interactivity.

To achieve this desired behavior, it's important to understand that the current CSS specifications do not provide direct support for modifying the option's background color on hover. CSS selector rules such as option:hover { background-color: yellow; } are ineffective.

One potential solution is to utilize third-party libraries like Chosen or select2. These libraries offer comprehensive styling options, including the ability to customize the background color of hoverable options. However, using these libraries introduces an external dependency.

An alternative approach, albeit more complex, is to convert the select list into an unordered list using jQuery or similar JavaScript libraries. By creating a custom unordered list, you gain complete control over the styling, allowing you to define the background color of hovered options. Here's an example:

<code class="html"><ul id="select-list">
  <li value="1">One</li>
  <li value="2">Two</li>
  <li value="3">Three</li>
</ul></code>
Copy after login
<code class="css">#select-list {
  list-style-type: none;
  padding: 0;
}

#select-list li:hover {
  background-color: yellow;
}</code>
Copy after login
<code class="javascript">$('#select-list').hover(function() {
  $(this).css('background-color', 'yellow');
}, function() {
  $(this).css('background-color', 'initial');
});</code>
Copy after login
