Automation to add new multiselect options

I’d like the contents of a single line field to automatically be added to a multi-select field. This is meant as a workaround as Airtable doesn’t allow creating new options from a form, so I’d have the user create a new option in the single line field - and then this will auto-populate the multiselect field.

Just create an automation that is triggered when your form is submitted.

Then, for your “update record” action, set the value of the multi-select field to the value of the single line text field.
