Optionally, buyers may be presented with any number of checkboxes on checkout. Checkboxes may be configured within by clicking Checkboxes under Settings. Example uses are for agreement to terms and conditions of sale, or to sign-up to receive newsletters. Checkboxes may be made optional or mandatory for checkout.
The Title field is the text that accompanies a checkbox. This field supports two special tokens to link to text or an external URL. Documentation for the supported tokens can be found by hovering over the 'info' icon when adding or editing Additional Fields.
The External Text field supports formatting with Markdown. A guide to Markdown can be found here: Writing with Markdown.
