The embedding feature of Airtable, as you’ve seen, doesn’t have very much customizability. It’s sort of a “take it or leave it” situation.
If you don’t know how to code, there are other tools out there that have already done all the heavy lifting for you.
For example, Pory.io was specifically designed to give you different types of gallery views based on your Airtable data, and you can even use your own website’s domain with it, so people aren’t leaving your domain.
Another great option is MiniExtension’s tool to embed an Airtable gallery on your own website.
Both of those options are specifically designed for Airtable.
But let’s say you find another popular gallery-building website app out there that has nothing to do with Airtable. If it’s popular enough, there’s a good chance that it will be listed on Integromat or Zapier, in which case you can seamlessly send information from your Airtable database to those other sites.
So you’ve got lots of different options to explore, but they will require you going outside of Airtable’s built-in native features.
