I have one one form with 2 drop-downs. What i want is, when I select 1st drop down box, then a specific option gets fixed (which can't be change by user in that form) to another drop-down box. How can i do this in javascript or jquery?
<select id="item_type" name="item_type" style="width:300px;" ">
<option value=''>-- Select --</option>
<option value="City">City</option>
<option value="Source">Source</option>
<option value="Follow Up">Follow Up</option>
<option value="Next Day">Next Day</option>
</select>
<select id="item_value_type" name="item_value_type" style="width:300px;" ">
<option value=''>-- Select --</option>
<option value="value">value</option>
<option value="id">id</option>
</select>
