How can I do so that a list and its pictures are never altered from the list?

[Gui Zanoni]

I need to block a specific list so that the items will not be altered, they will only be read by members of the picture. How can I run isso?

Hey @Gui Zanoni! I'm unsure if I followed your question, but if I got you correctly, do you want to block users from modifying the checklist items of a checklist? Or do you want to block users from editing and modifying the attachments of a card on your board? Knowing more about what you want to do will help me give you a better answer.

Hello Salomão, ty so much. I would like both. I want to create an explanatory board with sticky cards with directions, tips, welcome and onboarding. As in the attached image. And in this list, that frames were unchangeable. Just for reference, as if an administrator had placed it and only he could change the order and content. The other lists, free. Normal

If you want to prevent other users from changing your cards or moving them to other lists, you could try using the Observer feature available on the Premium Plan. Observers are a type of board member with lots of restrictions to what they can and can't do on a board, and one of them is the restriction to move cards across lists. I'd recommend checking whether the Observer feature is worth it for your use case and, perhaps, upgrading to Premium (if you haven't already).
