How to create drop down menus other than in CSS3? I don’t want to use custom libraries as I want to learn more of other web languages.
javascrip can help.... check hotscripts.com
Cascading menus aren't CSS3; they're just CSS, and they work cross-browser.
No JS needed: http://csswizardry.com/2011/02/creating-a-pure-css-dropdown-menu/
One of the best ways would be using Java script! You can build very advanced drop-down menus.. Also with great design too! How you can create drop down menus with js, is very complicated, and I can't explain it here.. But you can check various tutorials online!
What you are talking about is Cascading Menu's. Where do you want to create these? A web site or your right click context menu?
You can use DHTML for example. Manually or using third-party programs
Why you don't want to use CSS3?
Coz many people still don't have css3 browser...
I used that feature a while ago in Adobe Dreamweaver CS3, it was under Spry or something like that. I believe that it is only available in Dreamweaver though. I hope I've been of some help.
