I have a contact database and I want to make it easier to sort so I have developed a list of categories a customer can fall under using a checkbox system. Is it possible to have a "main" checkbox and then have "sub" checkboxes underneath that? For instance, a Donor Category checkbox would have "Individual" and "Foundation" underneath it. I want it so that for instance if "Individual" is checked, the "Donor" is checked too.
How can I achieve this? Thanks.
