Attributes with Drop Downs or Dates (in v16)

Does anyone have cheatsheat/reference documentation on adding/creating Attributes, specifically with drop down or date options (separate attributes)? I have been trying to create one of each and am getting nowhere. The Tessitura documentation is not really helping me (we've moved to V16 so I am referencing both 15 and 16 docs with the hope of understanding).
