Fixed #10919 -- Added delete_confirmation_max_display to ModelAdmin.

2026-04-23T02:22:55Z

The new ModelAdmin.delete_confirmation_max_display attribute allows limiting the number of related objects shown on the delete confirmation page. When the limit is reached, a "…and N more objects." message is shown. The feature relies on a new truncated_unordered_list template filter added to django.contrib.admin.templatetags.admin_filters. Thanks Jacob Tyler Walls for the review and guidance, Tobias McNulty for the report, and terminator14 for the solution suggested.
