Is it possible to create a multi-select lookup from entity metadata in Freedom UI?

Hello ,

I am working on a Freedom UI modal page where I need to display entity schema metadata (field list) and allow the user to select two or more fields from that metadata.

Requirement

• Source data is entity metadata (not business records)
• User should be able to select multiple fields
• Selection should be limited strictly to the metadata values
• The control should remain interactive (not fully disabled)

What I have tried

• crt.DataGrid with multi-row selection (facing stability/UX limitations)
• Custom HTML / repeater components (not supported in Freedom UI)
• crt.Input with control: "multiSelect"
  • readonly: true → control becomes fully locked
  • enabled: false → selection not possible

Questions

1. Is it supported to create a multi-select lookup or multi-select input whose options come from entity schema metadata in Freedom UI?
2. What is the recommended pattern to:
   • prevent free text entry
   • allow only selection from predefined metadata values
   • support selecting multiple values
3. Are there any OOTB components or best practices for metadata-driven selection in Freedom UI?

Any guidance or recommended approach would be greatly appreciated.

Thanks in advance!
