we have designed some services where you can select a lot of items within (like roles for a system f.e.) but none of them is preselected because most requests are only for one role only. Some of our customers (like superusers) want to request all of the shown items and have to select them all by hand. This is very uncomfortable and it would be nice if there would be a way to do that with one click like the "reduce all" functionalety.
Does anyone implemented something like this via Java Script? Or is there an OOTB way to do that?
