Hi !
Whether you delete a file, a subcategory or a bookmark
the alert notification always calls the language variable "EDOCMAN_DELETE_CONFIRM".
a specific language variable would be needed for each one in order to have a customized message for the user.
Are you sure you want to delete this item? not suitable for
- the bookmark because you don't delete the item but just the shortcut as a bookmark
- the category because (currently) even if there are files and/or other subcategory(ies), everything will be removed
Thank you for your interest
