I have a lot of links like this

<A href="commoner.cgi?pg= category &ref=category_id1>category1</A>
<A href="commoner.cgi?pg= category &ref=category_id2>category2</A>
<A href="commoner.cgi?pg= category &ref=category_id2>category3</A>

(This convention of passing value to the reference page as above is called is called query string method, I think so)

I would like to convert this links to a drop down menu, I mean a select list
How can I do this such that , when we select a category
all this vales should pass to the reference page, and the reference page should work next



please help me
