On my old Drupal 7 site, I was able to group a set of fields and display them as a tab in the sidebar. I'm moving it to Drupal 8 and using the adminimal theme. I created groups and am using the details sidebar widget. I'd like my custom groups to appear at the top of the sidebar. I've assigned a weight of -5 in Manage Form Display, but they still appear in the middle of the sidebar (even after clearing caches). Is there a way to control the order of groups in the sidebar, or am I maybe using the wrong widget? Thanks.
I have tried using Vertical Tabs Config, but even after clearing caches, the order is unchanged.
