Hi, I need help please!

Not much experience in Javascript, I'm coding in flowcentric which uses xslt file to create the page.

I have an object/edit field where i want to display an image next to it,
with onclick of image:


- displays a dropdown (lookup from database)
- with no borders & displays the lookup text overlapping page script
- with exit(mouseout) drop down to hide dropdown
- with selection in dropdown to insert the selected to the object/edit field

Please Assist!

Regards
