What's the best experience to do the following:
The user will insert a new subject(text) only if it isn't in the existing list. So, it will be added to the existing list for all users.
I have implemented this with the following sequence:
If the user can't find the subject, then they click on the plus (+) button:
After typing in the new field, clicking the plus (+) button will add it to the list and select it.
Is there a better method to do this?
