Drop-down multiselect

Hey,  for a team project, we want to create a drop-down option for hobbies.  In which a user is able to add a hobby to a list and select multiple hobbies from.  Do you guys have a suggestion on how to make that work? For now, we have a drop-down menu, where we have to add options manually as values of the attribute hobby. Only one hobby can be selected through by the user.  Thanks for the help already.

Drop-downs that only allow a single choice, are a reference. Replace that with a reference set. On the User_NewEdit page right-click, select Add widget, type ‘ref’ and you will see them both.

Make sure that the association between User and Hobby is a *-*. If not, you will not be able to select a Hobby-attribute.
