I have a customized tab to specify test requirements for all parts, I could easily do that on the Item Type. I created a list with all the tests that can be done, and all the documents that must be attached based on the tests. Is there a way to link these two lists/dropdown menus together? For instance, if I select "Test01" from the first dropdown menu, can the second dropdown menu automatically select "Test01 Certificate"? I have created lists for both tests and test certificates but if I don't link them a user can potentially select Test01 and then request the certificate for Test02.
