If your application has a large number of nested entities, the "Nested Entity Menu" page allows you to customize the menu.

Go to the "Display Settings - Nested Entity Menu" section and add the necessary menu sections.

As a result, the entity menu on the item page will be more convenient and compact.

Menu sections can be sorted and set your own icon.

If the menu section contains only one entity, it will be displayed as a simple link to the entity page.
