/*
The ultimate DHTML drop-down code
Nick Nettleton
www.computerarts.co.uk || www.fluid7.co.uk
--
This must be the single most requested bit of code in the history of Computer Arts, so we've decided to make it user-friendly and adaptable for everyone. Stacks more goodies to come too - head to one of the above sites for regular infoa nd updates.
Works with v4 and v5 browsers - both IE and NS. Update for NS6 coming. Also, be aware there's no way to automatically centre layers in the window - a JS for this coming soon. In the meantime, stick with left-aligned.
Keep an eye out for update for NS6.
--
You can adapt, use and distribute this code under GNU public licence, as long as:
(1) You leave all the comment and credit lines in, including these ones
(2) You don't sell it for profit
--
If you want to tweak the code yourself, use the f7_droplayer to set the names of the dropdowns, and just call f7_showdrop(n) and f7_hdidedrop from onmouseover, onmouseout and other events. Swap n for the number of the layer as in the array.
--
Enjoy!!!
