is it possible to add <div> or <span> inside an <option> tag?

2019 UPDATE

This solution doesn't work anymore.

Checked in latest Chrome, Firefox and Safari.

---

It is possible to put a red circle after the text - http://jsfiddle.net/V8cvQ/

option:after {
    content: " ";
    height: 5px;
    width: 5px;
    background: #c00;
    border-radius: 5px;
    display: inline-block;
}

...

UPDATE

To have different color dots

HTML

<select>
    <option> select </option>
    <option class="red"> one </option>
    <option class="green"> two </option>
    <option class="blue"> three </option>
</select>

CSS

option:after {
    content: " ";
    height: 5px;
    width: 5px;
    border-radius: 5px;
    display: inline-block;
}

option.red:after { background: #c00; }
option.green:after { background: #0c0; }
option.blue:after { background: #00c; }

DEMO

No. According to MDN, this is what is allowed:

Permitted content: Text with eventually escaped characters (like é)

Nope, not possible. Or not valid at least.
