Opening a drop down and then changing the default value
<p>If I have a drop down box, how can I have a default selection (know how to do this) which will change to another member in the drop down upon opening of the drop down?</p>

<p>For example: My drop down has 2 values - "Hello", and "Hello Back". "Hello" is the default (0) value, but how can I display "Hello Back" when the drop down box is opened?</p>

<p>Thanks</p>
