Only “list type” of views, such as table, deck, gallery views can be selected as inline view appended to detail view for now. Calendar view is not supported as in-line view surprisingly.
Calendar view could be categorized as a sort of “list type” view, it should be supported to push as inline view.
To test this, I made a slice and made calendar view out of the slice and push VC and expression using select / ref_row targeting slice. Appsheet made Gallery view, while we have custom Calendar view which stands as default view for that slice.
We can place calendar view beneath the detaill view by using Dashboar d view, but this is now what I m looking for.
For me, this is buggy behavior, but was asked by Support desk to place a feature request down here.
