Hi,

I think its better to use AJAX to get the data from the database without refreshing the page.
use 'onchange' keyword in the combobox to call the function in javascript.

the following code may be helpful for u.

<select id="box1" onchange="insertcode()">
<option value="length">length</option>
<option value="size">size</option>
</select>

<select id="box2"></select>

js code:

function insertcode(){
if(document.getElementById("box1").value == "size"){
var custBox = document.getElementById("box2");
var opt = document.createElement('option');
opt.value = "small";
opt.innerHTML = "small";
custBox.appendChild(opt);

opt.value = "medium";
opt.innerHTML = "medium";
custBox.appendChild(opt);
}
}
