Use radio buttons when you have a group of mutually exclusive choices and only one selection from the group is allowed.
Radio buttons are used for mutually exclusive choices, not for multiple choices. Only one radio button can be selected at a time. When a user chooses a new item, the previous choice is automatically deselected.
When to use
Can be used in forms on a full page, in modals, or on side panels.
Used to change from one setting to another in a menu, page, or component.
Selection in lists
Used to choose a singular item within data tables or lists.
When not to use
If a user can select many option from a list, use checkboxes instead of radio buttons. Radio buttons allow the user to select only one item in a set whereas checkboxes allow the user to select multiple options.
The radio button component is comprised of a set of clickable circles (the inputs) with text labels positioned to the right. If there is a group of radio buttons, a group label can be added.
- Radio button group label (optional): Describes the group of options or provides guidance for making a selection.
- Radio button input: A radio button indicating the appropriate state. By default an option is selected.
- Radio button label: Describes the information you want to select or unselect.
Radio button labels are positioned to the right of their inputs in languages that read left to right. If there is a radio button grouping, they can be laid out vertically or horizontally depending on the use case and the structure of the UI. When possible, arrange the radio button and checkbox groups vertically for easier reading.
For languages that read right to left, it’s acceptable to place labels to the left of the inputs.
The radio button component is often used in forms. Forms can be placed on a full page, in a modal, or in a side panel. A radio button can also be used for changing settings in a menu or selecting a singular item in a data table.
Radio buttons in a form should be placed at least 32px (
layout-03) below or
before the next component. Spacing of 24px (
layout-02) or 16px (
can also be used when space is more restricted or if the form is more complex.
For more information on spacing in forms, see our form style guidance.
Group labels (optional)
If necessary, a heading can accompany a set of radio buttons to provide further context or clarity.
- A group label can either state the category of the grouping or describe what actions to take below.
- Use sentence case for group labels.
- In some cases, a group of radio buttons may be within a larger group of components that already have a group label. In this case, an additional group label for the radio button component itself is not needed.
- Regardless of whether the label is visible in the interface, a group label is always needed in code, whether it’s for one checkbox or a group of them. See the radio button code tab for more information.
Radio button labels
- Always use clear and concise labels for radio buttons.
- Be explicit about the results that will follow if the radio button is selected.
- Labels appear to the right of radio button inputs.
- We recommend radio button labels being fewer than three words.
- If you are tight on space, consider rewording the label. Do not truncate radio button label text with an ellipsis.
- Long labels may wrap to a second line, and this is preferable to truncation.
- Text should wrap beneath the radio button so the control and label are top aligned.
