Is it possible to generate fields which are "grouped" together when marked as Unlimited? For example, a select field with label "What time do you wake up?" lets the user select the day of the week (Mon-Sun) then beside it an empty textfield to type in the time they get up. These 2 fields are "grouped" together. Then if they want to add another day of the week (Unlimited), the new field generates a dropdown menu and a textfield together all over again.
NOTE: No CCK please. I'm using Drupal 7 and it's already in the core.
