Hi folks

I need to develop a dropdown menu with the following results:

value 1: upon selection and click on the search button, the page will be
linked to a result page on the same window
value 2: upon selection and click on the search button, a pop up window with
specified size without address bar or status bar.
value 3: upoon selection, the page will be linked to another page on the same
window.

I have been seeking for similar code but seems there is nothing available.
Would any body please help and provide me an example? Many thanks!
