Hi

I want to put some selects on my page to allow people to navigate through 3 levels of navigation i.e.

Department > Manufacturer > Product

but I only want to show one select at a time, so if someone selects from the departments it will reload page.php?department_id=1 with the manufacturers in that department and then they can select a manufacturer from the newly appeared select so it reloads again with page.php?manufacturer_id=8&department_id=1 and so on and so forth.

This I think will be fine, but I was wondering if I can get Ajax to do it without the page reload? I've got a couple of Ajax books which I had a flick through and couldn’t find anything matching it.

I’ve got some Javascript that will allow people to select the department, which then creates a new list in the select below it, but that means showing the select there with a "Please select from above" message which I would like to get around.

Any input appreciated

Cheers

You could get javascript to create the selects from scratch, as opposed to changing the values. Or you could put the selects in divs at 0 height, and show them (by enlarging height) when the correct option is selected.

I know what your asking is possible in AJAX, but personally i don't have enough experience in the field to give you an answer.
 
Hi

Thanks for the input, I managed to find a script that generated select options for additional selects based on a previous selections, and combine it with a script that hid and showed the selects.

Damn complicated, lines and lines of script but works like a charm! AJAX might be neater but time contraints means it'll have to do for now.
