Hi @chun_hing_yap

Here is a example for select_one with map appearance (also relevant for the question you asked here)

You can achieve it with a form "session" using the choice filter described in this post by @LN

I needed the same for an exhaustive inventory of 100m squares covering a coastal lake.

As @Ivangayton and @LN suggested here, we use two select_one with map appearance :

  • the first one hides already visited squares (centroids)
  • the second one all the grid.

Prefer OSM map renderer in your project preference to test.
Squares are located in South of France.
