ChipMultiSelectField<T> class

Chip variant implementation of MultiSelectField.

Displays as a compact chip that opens a dropdown menu when tapped. Ideal for filter bars or space-constrained areas.

Can use either:

  • data to auto-generate selection list (like standard MultiSelectField)
  • menuContent for fully custom dropdown content
