Just for clarification... this is the result when using the {fieldl_errors} tag pair... we need to add some additional variables to this

https://docs.expressionengine.com/latest/channels/channel-form/examples.html#entry-form-using-the-field-tag-and-inline-errors

Gut is that we should have field_label, field_name etc. available here... so we give details on issues at top of form when desired etc.

2 things here:

1. the example in the docs is wrong, it should be {field}: {error} not just {error}
2. the errors should not be duplicated of course

I'll submit PRs for both

Oh man- yes, {field} works. It does still sort of duplicate- I get:

title: This field is required.
url_title: This field is required.
field_id_10: This field is required.
field_id_11: This field is required.
seo_title: This field is required.
seo_desc: This field is required.

So just needs a doc fix and clean up the duplicates and maybe add more variables. So {label} I would definitely want, {field} would be the custom field short name (seo_title for example above), and then field_id_x might be useful to have, but I can't think of what to call it.
