Thank you it helped and how do we select all the check box initially.

[paramvir]

you would need to select all the options in the multiple select list from which dropdown checkbox is created.

Code: [Select]

<select name="cars" id="cars" multiple>
    <option value="volvo" selected>Volvo</option>
    <option value="saab" selected>Saab</option>
    <option value="opel" selected>Opel</option>
    <option value="audi" selected>Audi</option>
  </select>
