How can I customize the content displayed in a Custom Layout?
For example, when I try to change the image or other elements, Glide always shows the image from the first record of the table instead of the one I want.
I’d like to know how to link the layout or components so that they display the correct record, or how to customize the image independently (not tied to the first row).
How do you get to that screen? If you are navigating there from a collection in the previous screen, then you should already be attached to the correct row. If this is a tab or top level screen, then you may need to set a filter on the screen itself so that it connects to the correct table row.
When I create a new custom screen, a table with the first record appears by default
So a new Tab screen, or a new screen from an action or workflow?
Regardless, you should be able to set the filter on the screen so it connects with the row you want. Unless you are navigating to screen via a collection, all screens will default to the first available table row, I less you have Row Owners applied to the table or Filters applied to the screen.
