multi-tier dynamic drop down list
Posted on 2009-04-13
Hi- Total noob here.
I need to have a drop down list that populates a second drop down list which then populates a third drop down list. For example: the first might have 3 options [A,B,C]. The next would have options loaded according to the selection of the first. For example [A1,A2,A3] or [B1,B2,B3,B4,B5] or [C1,C2]. When the 2nd list's selection is made, the third list is populated accordingly. So the third list might have lists like this waiting to be loaded - [A1a,A1b,A1c] or A2a,A2b] or [B1a,B1b,B1c] and so on. I hope this makes sense to someone.
I would be grateful for any leads to tutorials or examples of the 3 tier thingy I've described.
TIA your expert input.
