Menu
I would appreciate if anyone could guide my point by point on how one could create a category picker just like gumtree (preferably in jquery):
[url]http://www.gumtree.com/add_posting.html?location_id=uk
Specifically the points
[LIST][*]
How clicking on a category opens another to the right
How clicking on a category appends a variable like “#cat-10201” into the url (and vice versa)
How css lists are used instead of form select menus (making it easily styled)
How clicking on a deep subcategory automatically preselects all parent categories
I’m not looking for anyone to actually code it for me (that would be outrageous :p) but tips on how it’s actually structured and steps on how it can be coded would be highly appreciated. I can do PHP and I know CSS also. I don’t know plain javascript but I’m sure I can do most of it in jQuery
