Group tag selector not allowing a selection

Hi there

I’m new to using form templates so hopefully this is just me overlooking something.

I’ve created a form template that populates a dropdown from a tag group, which shows up correctly, but it doesn’t allow me to select anything.

  • The category does have 3 tag groups restricted to it, with “also allow other tags” unchecked
  • There are no categories specified in the “required tag group”, although ideally I’d like to have the same 3 tag groups specified here

The yaml for my form is:

- type: tag-chooser
  id: issue-type
  tag_group: "Issue Type"
  attributes:
    none_label: "Select a type"
    label: "Type"
    multiple: false
  validations:
    required: true

- type: tag-chooser
  id: issue-priority
  tag_group: "Issue Priority"
  attributes:
    none_label: "Select a priority"
    label: "Priority"
    multiple: false
  validations:
    required: true

The preview loads fine:
discourse-preview

But the form itself on topic creation, doesn’t allow me to select any tags:
discourse-form

All tag groups are similar in set up -

Any help appreciated. As I said, hopefully something simple :crossed_fingers:

And does that included the tag groups you are using here (“Issue Type” and “Issue Priority”)?

Thanks for the reply!

Yes, those two are included

I’m having trouble reproducing the issue locally. @Parker1090 what version of discourse are you running?

2026.6.0-latest (c61074ebf8)

Happy to give any other details as needed

Thanks, I managed to reproduce the issue locally by using mixed case tag names.

Amazing, thank you for your help!
