Syntax for discussion category forms

You can use YAML syntax to define the fields in your discussion category forms.

About YAML syntax for discussion category forms

You can create custom discussion category forms by adding a YAML form definition file to the /.github/DISCUSSION_TEMPLATE/ folder in your repository. If you're new to YAML and want to learn more, see "Learn YAML in Y minutes."

The name must correspond with the slug for one of your discussion categories. For example, the template for the "Announcements" category should be .github/DISCUSSION_TEMPLATE/announcements.yml.

For each field, you can define the input type, validation, and a default label.

When a community member fills out a discussion form, their responses for each input are converted to markdown and added to the body of a discussion. Community members can edit their discussions that were created with a discussion form and other people can interact with the discussion like a discussion created through other methods.

This example YAML configuration file defines a general discussion category form.

YAML

labels: ["General Introduction"]
body:
  - type: markdown
    attributes:
      value: |
        This is text that will show up in the template!
  - type: textarea
    id: improvements
    attributes:
      label: Top 3 improvements
      description: "What are the top 3 improvements we could make to this project?"
      value: |
        1.
        2.
        3.
        ...
      render: bash
    validations:
      required: true

Top-level syntax

The configuration file for a discussion category form must contain a body key, and the body must contain at least 1 non-Markdown field.

YAML

    description: "How might we make this project better?"
    placeholder: "Adding a CODE_OF_CONDUCT.md file would be a great idea."
  validations:

You can set the following top-level keys for each issue form.
