I am writing a custom module, which handles Warranty Claims. The customer need to enter a Fault Area and a Fault Code, to fill out the form.
Each Fault Area has an Associated list of Fault Codes. The user need to select those from two select lists.
I would like to have the first list update the second, when the users selects the fault area.
The frontend only has prototype enabled, and I don’t want to add jQuery, just for this one function.
Is there a clever way to do this from Magento?
I know of Mage_Core_Block_Html_Select, and am looking into how to use it.
