# Collaborator fields

> Single and multiple collaborator picker fields on Filla forms.

## What this does

Collaborator fields map to Airtable's Single Collaborator and Multiple Collaborators field types. They present a picker that lets respondents select one or more collaborators from your Airtable workspace.

## Settings reference

Collaborator fields (both single and multiple) have no field-specific settings beyond the universal ones.

**Universal settings that apply:** Label, description, required, read-only, conditional visibility, conditional read-only, custom validation rules.

## How the picker works

The collaborator picker shows all members who have access to the connected Airtable base. Respondents search by name or email and select from the results.

For **Single Collaborator**, only one person can be selected. For **Multiple Collaborators**, multiple people can be selected.

## Common use cases

* Assigning a task or request to a team member
* Identifying who is responsible for a record
* Tagging stakeholders on a project submission

## Common questions

<AccordionGroup>
  <Accordion title="Can respondents outside the Airtable workspace use the collaborator picker?">
    The picker only shows people who are members of the Airtable workspace. External respondents (people who don't have access to your Airtable base) will see an empty list. If you need external selection, use a linked records field with a people table instead.
  </Accordion>

  <Accordion title="Can I pre-fill a collaborator field?">
    Pre-filling a collaborator field requires that the chosen person already be a member of the workspace.
  </Accordion>

  <Accordion title="What if my Airtable base has many collaborators?">
    The picker is searchable by name or email, so respondents can find the right person quickly even in large workspaces.
