Committee Membership Dropdown for Database

I need a dropdown list implemented in a nonprofit membership database. This dropdown will allow users to select multiple committees they have joined.

The membership database should include:
- Searchable member directory

The member directory should display:
- Name and contact info
- Committee memberships
- Membership status

Ideal skills and experience:
- Experience with database management systems
- Proficiency in creating dropdown lists and searchable directories
- Familiarity with nonprofit membership structures
