Multi select field

Description
Introduce support for allowing multiple select fields of the same type within a single entity, rather than using a single multi-select dropdown. Each field instance should act as an independent selectable value.

Business Value
This enables more flexible data modeling where multiple discrete selections are needed without forcing them into a combined dropdown structure.

Acceptance Criteria

• Users can add multiple instances of the same select field.

• Each field instance behaves as an independent single select.

• Users can add/remove individual select field instances dynamically.

• Existing single select behavior remains unchanged.
