Making Non-selectable options and option groups in select

Making Non-selectable options and indented option groups are pretty easy in select control. disabled the options is not a correct way to do, use optgroup option.

Making Non-selectable options :

<select > <option >groups</option> <optgroup label=”group1″> </optgroup> <option> group 1 item 1</option> <option> group 1 item 2</option> <optgroup label=”group2″> </optgroup> <option> group 2 item 1</option> <option> group 2 item 2</option> </select>

Making indented option groups:

<select > <option >groups</option> <optgroup label=”group1″> <option> group 1 item 1</option> <option> group 1 item 2</option> </optgroup> <optgroup label=”group2″> <option> group 2 item 1</option> <option> group 2 item 2</option >/optgroup> </select>
