Hey,
I’ve opened up a pull request (Fixed #14810 -- Added reusable blocks to the inline templates by alfawal · Pull Request #17030 · django/django · GitHub) regarding the ticket #14810 (Admin inline templates need blocks) – Django.
The inline templates (stacked and tabular) previously had no blocks and were difficult to extend or modify. I have now added blocks to the templates and would like to hear your opinions and suggestions to meet the needs where creativity is encouraged, as packages can be developed for the inlines with the blocks!
Please let us know what you think and what improvements you would like to see by commenting here or reviewing the PR.
Regards.
