Let us see your code

Include a link to the source code repository of your project, because we really need the context of seeing your templates and partials to be able to help you. It is trivial to do a quick git clone on your repo, then run hugo server in your project, to help you out. On the other hand, recreating your code from screenshots, or sort of guessing at it, is not.

If you can’t share your repository for whatever reason, consider creating a dummy repo that you can share, which reproduces the problem you’re experiencing.

Though not mentioned, you can DM a link to your repo to these folks here trying to help you (if it is a repo of reasonable size). Because you won’t receive any help if you don’t do so and your request will just be ignored.
