I'm using the ManyManyDataObjectManager for associating Pages to a DataObject called Group. As my website currently has 1400 pages it is nearly impossible to see the pages that are already linked to a group.
Is there some way to create a filter for that use case?
No, everything works as expected. I have a DataObject called Group which has a m:n connection to the Page object. So I select a group and get a tab called pages that shows me a list of all existing pages. The pages that are connected to the current group have a marked checkbox. As it is now the case I have 1400 pages and I would need some kind of filter that only lists those pages that are already connected.
