# Checkbox Allows users to make a selection or agree to terms. ## Guidelines - Checkboxes are used for one or multiple choices that do not exclude each other. - Each checkbox operates independently of other checkboxes in a list at the same hierarchical level. Checking an additional checkbox does not affect other selections in that list. - You can use a checkbox for bulk selection or deselection of an entire list of checkboxes. Still, it should be clear that the bulk selection checkbox is at a different hierarchical level than the list being fully selected or deselected. - Use a group of checkboxes to filter data on a page, in a menu, or within a component. - A checkbox can answer a closed question if multiple answers are possible. - A list of checkboxes is vertically stacked to enhance readability and usability. - A list of checkboxes should be in a `fieldset` with a `legend` describing what the list is about. For example, if the checkboxes are used to get answers to a question, the `legend` is the question. ## Checkbox labels A label starts with a capital letter. It does not have punctuation at the end if it is a single sentence, word, or fragment. It is written in the first person when asking the user to agree to the terms and conditions. ## Relevant WCAG requirements - [WCAG 1.3.5](https://www.w3.org/WAI/WCAG21/Understanding/identify-input-purpose.html): It is clear for both users and programmatically what the purpose of a form field is. Checkbox is an interactive element, and the [general requirements and guidelines for interactivity](/docs/docs-developer-guide-interactivity--docs) apply.
