Can't seem to group by content type in document sets

Question

I created two content types based on Document, no extra metadata, called Status Report and Timesheet.

I then created a content type based on the Document Set called Project. Added a couple of site columns of type Person and a managed metadata. I then added Status Report and Timesheet as "Allowed Content Types" in document set settings.

I have created a library and added the Project content type. That all works fine. I can create new projects and assign metadata. Inside the set I can create status reports and timesheets.

My problem is that I want to create a view which will group the documents inside the document set. I don't seem to have "Content type" in the group by drop down.

I am able to add content type to the columns of the view. It displays the correct data but I cannot sort or filter on this column.

Have I done something stupid?

Answer 1

Use a workflow to copy the value of the content type field into a new text field, then use this field to group by.

Answer 2

I have tried this and can't either. The easiest way is to simply edit the page in SharePoint Designer and do the grouping that way.

Answer 3

Seems like the content type is not available for grouping in Designer either... Or I don't know how to display it. I opened the AllItems.aspx and clicked Sort&Group in the ribbon. But the column Content Type isn't there. Can you give me a hint how to do it? Thanks a lot!
