Is there a way to deactivate a category so that it isn’t a choice any more or, are there plans to add this feature in the future?
Adam Tucker commented
I would like to add to this by asking for an inactive feature for both events and work orders. For work orders, I would also like a second option for Public/Private to allow certain service categories to be for internal use only. An example would be for internally escalating issues to another team that doesn't need to be listed on the public form.
