Hi,

In Drop down list, I want to display cities in state, group wise.

Here is my Code:

<select id="Select1">
                <option>------Andhra Pradesh-----></option>
                <option>Hyderabad</option>
                <option>Visakhaptanam</option>
                <option>Tirupathi</option>
                <option>Vijayawada</option>
                <option>------Maharastra-----></option>
                <option>Mumbai</option>
                <option>Pune</option>
                <option>Nagapur</option>
                <option>Thane</option>
               </select>

but, I want to display cities state wise and select only cities, not the states
In above drop down list i can select state also .

Solution to this problem is, specifying <optgroup> in select list.

Here is the code.

<select id="Select1">
                <optgroup label="-------Andhra Pradesh-----" title="Andhra Pradesh">
                <option>Hyderabad</option>
                <option>Visakhaptanam</option>
                <option>Tirupathi</option>
                <option>Vijayawada</option>
                </optgroup>
                <optgroup label="------Maharastra-----" title="Maharastra">
                <option>Mumbai</option>
                <option>Pune</option>
                <option>Nagapur</option>
                <option>Thane</option>
                </optgroup>
            </select>

Thank you.
