We have a scenario where we want to allow users to submit items but without been able to edit them or delete them. we only want admin users to be able to edit and delete the submitted items. so for this i created a new Permission Level, which is a copy of the built-in contribute permission, but i uncheck these 3 highlighted check-boxes:-
the issue i am facing is that users with this custom permission level can create a new list item, but they can not attach files to it, where the attachment control will be hidden, as follow. here is the create form for users with this custom permission level:-
unlike the admins which have an attachment control:-
any advice on this please? how we can allow users with this custom permission level to attach files?
