On the online voting system that I am currently working on, I am preparing for the voting feature. I plan to remove an item from the RecyclerView that the user has already voted on but in a way that it does not remove it from the Firestore database itself. Is there a way to do that? If not, is there any workaround to make my concept work? Thank you in advance for the responses.

The simplest solution would be to add a field of type boolean with the default value of false, into each document. You can simply call it "deleted". When you want to perform a delete operation, don't remove the document from the database, rather change its value from false to true.

If you want to have a temporary removal, you might also consider moving a document from a location to another.

If not, is there any workaround to make my concept work?

You can also use Cloud Functions, to trigger a function that contains a particular logic, when a delete operation takes place.
