This layout has an upvote feature, which can be used by the users to upvote list items. For this purpose, you need to have a number type field in your Airtable base to be linked to the Upvote parameter in the list configuration (see below).
The number of upvotes received by each list item will be updated in the Airtable base.
The upvote field on Airtable needs to have default values (e.g. "0") for all the rows to work. Airtable allows assigning default values to the whole column at once.
