patch

Update the default entity page extension component to support grouping multiple entity content items in the same tab.

Disable all default groups:

# app-config.yaml
app:
  extensions:
    # Pages
+   - page:catalog/entity:
+       config:
+         groups: []

Create a custom list of :

# app-config.yaml
app:
  extensions:
    # Pages
+   - page:catalog/entity:
+       config:
+         groups:
+           # This array of groups completely replaces the default groups
+           - custom:
+               title: 'Custom'
