Hi,
Bug or missing feature, I'm not sure, but here's what I'm facing.
In the PIM, the Add to group option (that works for multiple selected products in the [filtered] list) doesn't show the group tree when opened. Using the search in the upper-right corner of the dialog returns groups with matching names, but only a single one can be selected.
This dialog should in my mind initially show the entire group tree, like the same dialog does when editing a single product in the Ecommerce part - including the option to select multiple groups at the same time.
Generally on improving this dialog, it would be great to have the tree also for the search results (showing parent nodes either as an actual tree, or just before/after the group name.
Best regards,
Tolli
