English Translation (via Google Translate):
Good morning, I have the version of osTicket (v1.14.3) and create some custom lists called Category, Subcategory and Element to which several Items are imported in bulk through a CSV file, but now that I want to add a new item I I get a message that Element is a required field.
That just means you have the
Elemento field as a Required Field. You can go to the List, go to the Properties tab, find the Elemento field, click Config, go to the Settings tab, and un-check Required for Agents and/or End-Users.
