How to Encode column having Multiple value in the prefill form (Either Multi Select or link column)

I have multiple values in one column which I am trying to use for prefill form but its not working.
If there is single value then its working but for multiple value it does not.

The column can be linked records or multi select.


If I select Company A then show contacts only those which are linked to Company A.

Is that Possible?

How to do that with some twisty method?

I don’t think you can do this via Airtable forms. You’ll need to use something like miniExtensions I think

Here’s an example URL of prefilling multiple values:,B

The link which you have provided me for prefill is something which I want.
Can you please provide me in more details, so that I am able to do it.

Here an example of what I am showing you the my column which has multiple values and it is linked column or lookup column.

This is the column with multiple values

After applying the encode url formula

This is the prefilled form link

This is an example where there are three contacts for a company

You just need to put a comma between each value

Here’s the relevant bit from the documentation
