How to hide certain items in a term reference field?

Question

I have the taxonomy 'Types' with terms A, B and C. I've added a term reference field 'Type' to the users with the 'Types' vocabulary. Now, when people register, they can choose between A, B and C in the 'Type' field, but I'd like them only to be able to choose between A and B.

How can I hide the third option?

Answer 1

You can use the Entity reference module to achieve this goal.

1. Install Entity Reference module.
2. Create a view of terms, with a display type of Entity Referance, and your filters/conditions
3. Create a field of Entity Reference type.
4. In field settings: Choose its target type is Taxonomy Term.
5. In entity selection mode choose 'Views Filter by an entity referance view'. Choose the view you created above in 'View used to select entities'.
6. Now save it.

Answer 2

With core features, I believe you can't hide certain fields from being selected in the field.

Term Reference Filter By Views is a handy module for this. Install the module, and create a View (taxonomy terms) and add whatever filter you want to use to hide the terms that you don't want to make available (a Term ID exclusion will do). You will need to use a certain Display (read module's doc) in the View.

In the front end, user will be able to autocomplete or select the terms, but the list/pool is generated through the View, so your filters are applied automatically.
