Hi misters,

I need to implement Hierarchical DropDownList , like this

Option Parent 1
Option Child 1
Option Child 2
Option Parent 2
Option Child 1
Option Child 2

The user cannot select parent option, only child.

Any help, sample code will be very grateful.

Thanks in advance., best regards, greetings.

If your parent groups may not be nested, you can use <OPTGROUP>
element within a <SELECT>

<SELECT>
<OPTGROUP LABEL="Option Parent 1">
<OPTION>Option Child 1</OPTION>
<OPTION>Option Child 2</OPTION>
</OPTGROUP>
<OPTGROUP LABEL="Option Parent 2">
....
</OPTGROUP>
</SELECT>

The DropDownList control doesn't support that option, but you can
override it...

Hope this helps
