Description

Tag icons are great but they don't appear on the tags index page. It would be nice to have consistent icons between page, search and tags index.

I've tested with a quick setup:

mkdocs.yml

site_name: My Docs

plugins:
  - tags:
      tags_file: tags.md



theme:
  name: material
  icon:
    tag:
      html: fontawesome/brands/html5
      js: fontawesome/brands/js
      css:  fontawesome/brands/css3


extra:
  tags:
    test: html

docs/index.md :

---
tags:
    - test
    - trigger
---

On search:

But not on index:

Fixed in squidfunk/mkdocs-material-insiders@a733eca. Tag icons were not forgotten on the tags index page, but the mapping was missing – the tag name was used, not the icon mapping. Furthermore, search will now also display the # symbol, when no specific tag was set, but icons are used.

Released as part of 8.3.9+insiders-4.20.0.

Thanks! So it was a mini minor bug ;)

furthermore, search will now also display the # symbol, when no specific tag was set, but icons are used.

To be sure, in the case where a default icon is defined it is this one that will be used?

Jup, if you define tag icons, but have no specific icon defined for a tag, the default icon is used.
