Dear all,

I'm developing a biological database using Zope 2.6 and pgsql. Let me explain my issue with an example. There is a menu called Drug in my homepage, by clicking the menu only the drug names along with their types in two different columns get displayed in the body. I can do things till that. My problem is , lets say there is a link called "Isoniazid" with all other links(drug names) in it.
When a user clicks one of the links as i said before as "isoniazid" only the information about isoniazid has to be displayed , likewise to all the other drug links. I have no idea how to capture the click event and the data to be retrieved. Can someone help. Thanks in advance.
Dear all,

And another query, how can i select text from a dropdown box. I just need the data which is selected in the dropdown box and sent as query

Thanks again.
