Hi, I am struggling with this problem: in a page there are 2 combo box: category and subcategory. When I select a category the subcategory combo must update its values.

I would like to use JQuery with Ajax to load subcategory after category change.

It important the page works also without Javascript, Do you have some idea to accomplish that ?

thank you ! Alessandro

I'm assuming you mean list boxes here. Comboboxes are slightly different.

observe_field should do it.

Yes. You'll need to submit the form after the category is chosen if you're doing without JS. There's no other way.

Best,
