Form fields that allow users to pick a single item.
About this component
Radio buttons are a form component that allows users to select a single item from a list of options.
Why we use this component
We use this component when we want users to be able to only pick one option from a list.
If there are lots of options, you should think about whether a select component would work better.
If users need to be able to pick more than one option from a list, use the checkboxes component instead.
Other versions of this component
Radio buttons with hint text
Hint text can be added to radio buttons. You can use hint text for more details about a radio button. You should avoid adding hint text to the radio button’s label element.
Small radio buttons
Although small radio buttons appear smaller, their clickable area remains the same as normal radio buttons. This makes them easier for users to select.
The error state for radio buttons marks the entire fieldset.
Revealing additional questions
If there are additional questions that apply to a particular radio option, they can be made to display only when that option is chosen.
- make the related questions easier to answer by grouping them together
- make the form simpler for users who do not need to complete the related questions
Inline radio buttons
In some cases you can display radio buttons beside one another.
Only use inline radio buttons when:
- the question only has two options
- the text for both options is short
If you are using an inline display for a yes/no choice, make ‘Yes’ the first option.
Inline radio buttons have some limitations. You cannot use ‘hint text’ with inline radio buttons, and they cannot be used to reveal additional questions or content.
Radio buttons can be tracked through the original page path and a data attribute showing the question type and value selected.
The data attribute is added automatically by the Design System’s “tracking” script.
We use a custom style for radio buttons so that they’re larger and easier to use than the standard radio buttons defined by the user’s browser. We also use a custom style to make their focussed and selected states clearer.
