Good afternoon,

I am looking for a way to select all the points from a point layer that fall within a selected polygon. Which widget can I use, and how should I configure it?

I have a Commission District polygon layer where I can select a single district using the Filter widget. The next step is to select all the points that fall within the selected Commission District polygon.

Here's a build for finding points in a polygon.

Greetings, José. To Solve this spatial selection Experience Builder without any margin for error, the golden rules is to first ensure the georeferencing and exact coordinates of the asset within the polygon before running any queries.

Once the data is clean and validated , the recommended architecture is a follows:

* Step 1 (Spatial Overlay) : Configure the Query Widget using a spatial relationship type of Contain or Intersects linked directly to your district polygon layer.

* Step 2 (Zone Automation) : Leverage the Zone Lookup widget ( as mentioned in the community references) to automate the filtering of point entities falling within the selected area.

* Step 3 ( Dynamic Triggers) : Configure Message Actions in experience Builder so that the district polygon selection acts as the trigger updating the point layer in real time.

By guaranteeing coordinate integrity right from the source, the system will respond with surgical precision. Greetings from the field!
