with simpleCombo, you can turn select lists into combo boxes like this:
$(
selector).simpleCombo();
Simple combo boxes are normal select lists with one extra feature: you can type directly into the combo box to add an extra option, which is automatically selected.
Since these combo boxes are actually just select lists plus JavaScript, they look exactly like regular select lists. They can be styled, resized, etc. with no visual glitches.
Add combo box functionality to all select lists with the "allow-edit" class.
$('select.allow-edit').simpleCombo();
You can play around with the Simple Combo demo.
