How to hide an item from a gallery?

Posted on by Ts01

Hi all,

I have a Power Apps gallery and the data source for it is a collection called "colChat". The gallery's fields are "role" and "content". I want to hide (not show to the user) only the first item of colChat, without deleting the item from the collection. Is there anyway i can do this? I have tried with filter, patch and some other approaches and always faced a dead end.

Thank you very much in advance.

Hi @victorcp. Thanks for getting back.
I used items = LastN(colChat,CountRows(colChat)-1) but unfortunately it still prints the first item in the gallery.
EDIT: When previewing the app it works as it should. It hides the first item. But when i play the app it does not work. Am i doing smth wrong? (Total noob here...)

@victorcp Your answer works. In preview it works as it should. However, when i play the app it does not. I guess that the last version is not live. Please see the attached screenshot.

you have to publish to your changes take effect here:

you can also edit the details before publish, but it is opcional

Sometimes it take 1 or 2 min to be visible in play mode if it take longer than that try to clean the cache using ctrl + F5
