Hi @Patrick_Blattner

Welcome to the Airtable Community! Thanks for sharing your request for conditional single select and multiple select fields.

Unfortunately, we don’t currently support conditional select options in a field. This is something we’re considering eventually supporting, but I don’t currently have a timeline for doing so.

I’d love to pass this feedback along to my team as a way we could improve the product further – thanks for surfacing it! Also, you can stay on top of Airtable product changes from our What’s New Page.

2025 Update:

You can now successfully do this by using Airtable’s dynamic filtering feature and matching the same field types between 2 tables.

If you’re trying to add this feature to a form, note that this requires you to set this filtering feature at the FIELD LEVEL (i.e. for your entire base), instead of just setting it at the FORM LEVEL (i.e. just for your specific form).

It is often easier & better to do this with Fillout’s advanced forms for Airtable.

With Fillout, you can leave all your fields alone in Airtable, and just setup a form that has this dynamic filtering feature.

Fillout is 100% free, and it lets you update existing Airtable records with a form or create new records in Airtable.

You can use Fillout’s dynamic filtering features to filter your linked record fields to only show the user the linked records that you want them to see, based upon other data.

Fillout also offers hundreds of other features that Airtable’s native forms don’t offer, including the ability to update Airtable records using a form, create custom PDF files from a form submission, accept payments on forms, pre-fetch dynamic data from an Airtable record, display Airtable lookup fields on forms, create new linked records on a form, add a login page to your form, perform math or other live calculations on your forms, collect signatures on a form, create multi-page forms with conditional paths, connect a single form to dozens of external apps simultaneously, add CAPTCHAs to your form, and much more.

I show how to use a few of the advanced features of Fillout on these 2 Airtable podcast episodes:

• Using Fillout to update an existing Airtable record, and create an eSignature approval process with PDF file creation.
• Using Fillout to create an order entry form with line items.

Hope this helps!
