I would like to know how to control the information that is added to a list, not to be duplicated

Hello, I would like to know how to control the information that is added to a list, not to be duplicated. Ex: if I have the items “White”, “blue”, “green”, “yellow”. and I want to add another color let’s say “Green”, which does not accept it and shows a message that is already in the list. Thank you very much for the help you can give me, since I am beginning to know the glide tool.

You should be able to achieve that with a custom form. Add a relation from your color entry to the existing list of colors. If the relation is not empty then show the error message and hide the submit button.

Hello, according to your suggestion, I decided to see the app that offers a solution to my question above, and when I copy it, it asks me to enter my Glide account, and I continue, but I see that my apps that I have made so far do not appear, what happened ?, I strongly ask you to help me with this problem, because I ran out of my applications. Thank you

It seems that glide creates another section with the same name where I have my applications, and another one for the application that I copied

The example that you indicate seems to be not case-sensitive when entering the name of a new animal, and neither in editing.

Firstly have you got your dashboard back to “normal” yet?

It should be case-sensitive, can you include some screenshots or a video of what’s happening?

The example there was just for adding. For editing you would need to have basically the same setup, creating multiple user-specific columns to house the “edited” values, then when users want to commit the edit, set them to the real columns.
