Populating multiple drop down lists with different options

Hi all,

I am creating a tool for users where they will select multiple options using drop-down lists. There are ~150 drop down lists total, and each list needs to have different options in the drop down list.

I have a master list with ~270 rows that lists each option for each drop-down menu. What I am envisioning is some version of a vlookup where it takes the category listed and then populates the drop-down list with each option associated with that category on the list.

Example 1:
Category: Conferences

Master List:
Conferences Level 1
Conferences Level 2
Conferences Level 3

[So, the drop down list next to "Conferences" would contain Level 1, Level 2, Level 3]

Example 2:
Category: Event Production

Master List:
Event Production Level 1
Event Production Level 2

[So, the drop down list next to "Event Production" would contain Level 1, Level 2]

Any help/ideas would be greatly appreciated!
