Element Position

Dear Community

I have the following problem:

I want the player to be able to choose from a number of different resources.
These resources (and only these) should then be available for selection at another point in the game.
So only the selected ones should be displayed. However, these should be listed without spacing.
So a simple “Hide Object” does not work, as this creates a gap.

Does anyone have an idea how I can solve this problem?

Thank you very much
