Adding Icons to the Option Elements of the Select Tag in Firefox. Quick and Dirty

Below is a quick and dirty solution for adding icons to the <option /> elements of the <select /> tag utilizing CSS generated content.

Disclaimer: According to the CSS specs, the <option /> element should not support generated content, and this solution works only in Firefox. Anyways, it may come handy sometime.

The Result:

The CSS:

[sourcecode language=”css”]
.acidjs-cssw-select-icons option::before
{
    content: "";
    display: inline-block;
    vertical-align: middle;
    margin: 2px 6px 2px 2px;
    width: 16px;
    height: 16px;
    background: url("path/to/the/icon.png") no-repeat center;
}
[/sourcecode]
