Indexhibit Support

Hi, thats my site: maayanl.com/
since i added more projects - the list came too long and i cannot reach the bottom of the main menu list.
how can i add an open/close function to each section?
or, if undoable - a scroll to the main page?

and how do i add a big pic to the main page?

thanx a lot!

I don't see an Indexhibit site in theat url address.
