Yes, both things are possible but you aren't being clear about what you want.

A content control sits in the document itself and they come in different types, some of which provide a drop down list that can be clicked on and allow selection of an entry. This doesn't necessarily require VBA and is relatively simple.

You can also customise the ribbon to add something that drops down to reveal a list of selections. This can be way more complicated and require VBA and xml CustomUI skills.

Can you explain exactly what it is you want to do?
