In a situation where a property in a PageType/BlockType, there is a component which allows the editor to select one och many of the available choices.
There is a lot of choices and is there a way to have a "Select All" and "Deselect All" toggle in the top on the selection?
Well, there is nothing available Out-of-box. But, you may try it by customizations.
I was just wondering if you found a solution to this or have any good starting points?
