drop down for selecting Query

Hi,

I have a webtemplate where in 10 queries are displayed in one webtemplate now my user wants to have one drop down called Report and have all the 10 Queries to be used as the values

So that defaulty the when the user execute the webtemplate it should show all the 10 Queries .As soon as the user selects particular Query from the dropdown box Report it should only display that particular report and hide rest of the reports

How can this be done in WAD 3.5

Regards

Maya
