Note

GitHub's form schema is currently in beta and subject to change.

About GitHub's form schema

You can use GitHub's form schema to configure forms for supported features. For more information, see Configuring issue templates for your repository.

A form is a set of elements for requesting user input. You can configure a form by creating a YAML form definition, which is an array of form elements. Each form element is a set of key-value pairs that determine the type of the element, the properties of the element, and the constraints you want to apply to the element. For some keys, the value is another set of key-value pairs.

For example, the following form definition includes four form elements: a text area for providing the user's operating system, a dropdown menu for choosing the software version the user is running, a checkbox to acknowledge the Code of Conduct, and Markdown that thanks the user for completing the form.

Keys

For each form element, you can set the following keys.

Key	Description	Type	Valid values
`type`	The type of element that you want to define.	String	`checkboxes` `dropdown` `input` `markdown` `textarea`
`id`	The identifier for the element, except when `type` is set to `markdown`. Can only use alpha-numeric characters, `-`, and `_`. Must be unique in the form definition. If provided, the `id` is the canonical identifier for the field in URL query parameter prefills.	String
`attributes`	A set of key-value pairs that define the properties of the element.	Map
