make custom list item column unrequired (non-required)

Question

I have a custom content type with many required columns. The UI does not allow me to change a column from required to non-required (at least, I can't find a way to do it).

Is there a way to achieve this in the database or another means?

Otherwise, it seems all the fields have to be recreated -- a major pain with dozens of fields.

Answer 1

I found the solution. To achieve it via the UI, I go to Site Settings, Site Content Types, click on the custom content type, then click each field and voila!
