Guidance
When to use
Checkboxes
- When a user can select any number of choices from a set list.
- When a user needs to choose “yes” or “no” on only one option (use a stand-alone checkbox). For example, to toggle a setting on or off.
- When users need to see all the available options at a glance.
- When users should be able to select zero of the options.
When to consider alternatives
- If there are too many options to display on a mobile screen. Consider a
dropdownmenu if you don’t have enough space to list out all available options, and if the user can only select one of the options. - Never use radio buttons for optional questions, since once a radio button is selected from a list, it or another choice will remain selected.
Usage
- Don't rely on the visual difference between radio buttons and checkboxes. Make it clear with words when users can select one or multiple options.
- Users should be able to tap on or click on either the text label or the checkbox to select or deselect an option.
- In general, list choices vertically; horizontal listings can make it difficult to tell which label pertains to which choice. An exception is where you have binary choices with short labels, like 'Yes / No'. The convention here is for horizontal alignment.
- Avoid using negative language in labels as they can be counterintuitive. For example, “I want to receive a promotional email” instead of “I don’t want to receive promotional email.”
- Use caution if you decide to set a default value. Setting a default value can discourage users from making conscious decisions, seem pushy, or alienate users who don’t fit into your assumptions. In addition, you'll never know if the user explicitly chose that option or just didn't notice the question. If you're unsure, leave nothing selected by default.

Checked children and the expose within pattern
- The
<Choice>component includes acheckedChildrenprop that can expose hidden text information or form elements. This expose within pattern is especially useful if you need to collect data from follow up questions or give just-in-time feedback. - Checked children can be exposed by checking the parent checkbox or radio button
- The
checkedChildrenprop should return one or more items wrapped in adivwith the following className:.ds-c-choice__checkedChild. This class sets the spacing and border color for the exposed elements. - Add the className
.ds-c-choice__checkedChild--inverseto thedivto show the inverse white border - You may need to add the className
.ds-u-margin--0to your child element(s) to avoid extra top margin - If you opt for smaller radio buttons or checkboxes, add className
.ds-c-choice__checkedChild--smallto your checked child container
Accessibility
- Surround a related set of choices with a
<fieldset>. The<legend>provides context for the grouping. Do not usefieldsetandlegendfor a single checkbox. - Some screen readers read the
legendtext for eachfieldset, so it should be brief and descriptive. - Each input should have a semantic
idattribute, and its correspondinglabelshould have the same value in itsforattribute. - The custom checkboxes and radio buttons here are accessible to screen readers because the default fields are moved off-screen.
checkedChildrenwill be announced to screen readers when they are exposed. They have been tested with the following devices:- Windows 10 + Internet Explorer 11 + JAWS screen reader
- Windows 10 + Chrome + JAWS
- Windows10 - Firefox + NVDA
- NVDA reads out the
<select>label and every<option>value
- NVDA reads out the
- MacOS Mojave + Safari + VoiceOver
