Hey Guy/Gals!
I need someone help to guide me in creating a drop down menu, where the first menu affects the second menu and it's selection. So in my database I have a category table that has a ID, parentID, and name. parentID is a FK to the PK ID within the same table. Can anyone please give me guidance or some links that may help me. I have been searching the interwebs for the past hour so I don't know how useful links will be to me, since I have literally searched everything. But any help would be nice.
If you need any other information please let me know. Thank you!
