Creating new set of dropdown menus on selection

[runway27]

when an option is choosen from a dropdown list using select tag and based on which option was selected How to create a new set of dropdown menu just beside the original dropdown list.

Also from this new drop down that a user selects how can this value be passed to a php file in order to read which value was chosen from the newly creted drop down menu.

please advice

Ok!
Try this code.

function change_options()
{
 var sel_ref = document.getElementById('sel2');
 sel_ref.options.length = 0; 
 //Make it empty if it contains some options previously.
 var op1 = new Option("value_here","text_here");
 //May be the sequence of value & text changed...Make sure of that.
 sel_ref.options[0] = op1;
 //Make the list in this way.
}
 

<select id = sel1 onchange = "change_options()">
.
.
.
.
</select>
<select id = sel2></select> <!--Empty Drop-Down Box-->
 

Good Luck. :)
