I work in a budget shop and I need to create a parameter based list on user
input.

I need a way to create a list based on they type of fund they select. For
example, if the user selects 001: General Fund, they see a list of
appropriations associated with this fund.

Data Example:

001: General Fund 011: Salaries and Expenses
- FY 1
001: General Fund 012: Salaries and Expenses
- FY 2
001: General Fund 031: Grays Harbor Coastal
Erosion-FY1
001: General Fund 032: Grays Harbor Co
Coastal Erosion-FY 2
