Describe your feature request

We noticed performance issues when using many inlines, because django loads the content with the initial page request, even if we limit the objects for inlines. A solution for us was to change inlines with simple properties which link to the changelist of the respecting models. This does work but it redirects a user to another page. It would be a better UX if the user could stay on the actual detail page.

Therefore I suggest, where possible, to add options to defer loading data and instead load them afterwards / on demand with AJAX. For example django-jet-reboot enables you to define autocomplete fields for choices which then will be loaded via AJAX on demand.

Another inline optimization would be this package (https://github.com/DmytroLitvinov/django-admin-inline-paginator-plus) which adds pagination for inlines.

It would also be a great benefit if django-unfold would offer the option to load inlines on click (by demand) and not with the initial page request.
