SelectBox replacement that allows html inside the options

I am looking for a select replacement that allows for good degree of customisation. In each option I want 2 fonts governed by CSS and structured by

<option><b>Option 1</b> options one</option>

Does anyone know a plugin that allows html styling like that.

Marvellous

You should try to plug that into the amazing jQuery "chosen" plugin:

Don't know what your budget is, but Telerik's RadComboBox is very customizable. You can even embed TreeViews and DataGrids in the select list.
