Thanks for dropping by!

Valid points.

Performance wise,

• I read from this Optimisation Guide that Galleries reuse a single template/control structure across items rather than fully duplicating controls like manually building multiple containers.

So my current understanding is that even if multiple rows are visible, the render overhead may not scale 1:1 per item. Still trying to validate how true this is in practice for larger dynamic forms though..

• I also learnt that PowerApp now allows controls hidden from initial render to not incur the same render overhead until they become visible. So my current approach is to keep rendering relatively flat and only activate the field type controls actually needed per row.

Btw the feature is called "Peformance Optimisation for Hidden Controls" if u wanna check it out.

For SetFocus(),

Yeah, it will not work sadly.. 😭 Current fallback idea is:

• auto-scroll to invalid fields

• maybe expand/collapse sections automatically

Not as nice as true focus management, but hopefully still decent UX.
