is there Any Dropdown <select> contains checkboxes?
<p>I need a dropdown menu <code>&lt;select&gt;</code> which contains multiple checkboxes.
so people can drop down and select many options (all the checkboxes should be inside the dropdown)</p>

<p>Sometimes this is called a combobox (just to make everyone understands what I'm looking for)</p>

<p>I want this with javascript/css &amp; not java applet or flash.</p>
