Dropdown list with checkable options

Is it possible to add a dropdown with a list of items to choose and that will be checked? What ever is checked will than populate / become visible to input data.

Example:
Name: well #1
Depth: depth 1
Depth: depth 2 and so on.
I will have around 30 different possible named depths that will be part of well #1 but may only need 5 that I want see and input data to.
