Power Apps YAML Snippet Tips - Gallery Data

Let’s be real — there’s nothing worse than pasting a beautifully designed YAML snippet for a gallery… only to see a bunch of blank rectangles. That’s what happens when your control depends on external data that doesn’t exist yet.

In this video, I’ll show you how to use hardcoded mock data directly inside your gallery snippet so that your design shows up immediately, no configuration required. This tip is essential if you're building a component library, sharing snippets with a team, or just want to preserve the visual intent of your design.

It’s fast, it’s foolproof, and it guarantees your paste looks pro.
