2. In the element's properties, configure:
  - Options: list of text to display (static or from database)
  - Placeholder: text shown when nothing is selected
  - Label: optional label above the field
  - Initial Values: comma-separated values to pre-select (e.g. "Option A,Option B")
  - Max Selections: maximum number of items (0 = unlimited)
  - Colors: Chip Background Color, Chip Text Color, Focus Color, etc.

3. Exposed states:

4. Events available for workflows:

  MultiDropdown's selected_count = 0
