I am having a hard time trying to find a tutorial on how to do this. When I search it always comes up with menu stuff so sorry if I missed a discussion about this.
What I want to do is make a 3 level drop down box that function in hierarchical manner (on a page not menu). You can see the current setup all on 1 tab at
So to make it clear what I am trying to accomplish is when you select the make of the vehicle the next dropdown populates with the models of that parent and on the selection of the model it populates the years available to the next and brought to that archive upon that selection of the year.
If i could get some help with this or even pointed in the right direction it would be awesome.
Thanks in advance!
