I have a task to change one drop down list to multiple select (in Clients -> Customers module). I’ve found on Studio Module builder all the fields and its’ types, but I don’t have possibility to change the type of each field (I can only change the list of it’s values).
I have Suite CRM v.7.10.5
Sugar v.6.5.25 (build 344)
In Admin / Studio / [module] / Fields you can add a field and choose field type, namely “Multiselect”. Don’t forget to add the new field to at least one of the views (Edit view, Detail view, List view) afterwards.
