Component

A Radio Button is a UI element used for selecting a single option from a set of mutually exclusive choices. Visually represented by a small circular button that can be filled or unfilled, Radio Buttons offer clear access and immediate feedback to users.

When selected, the button is filled in, providing a visual confirmation of the user’s choice. To ensure accessibility, Radio Buttons should be navigable using keyboard inputs and properly labeled for screen readers, which helps convey the available options and the current selection to visually impaired users.

Keyboard navigation should be supported, allowing users to navigate and toggle Radio Buttons using keys such as Tab and Spacebar.

Used for:

Single selection from multiple options

Radio Buttons are ideal when users need to select a single option from a list of mutually exclusive choices. This ensures that only one option can be selected at a time.

Visibility of all options

Radio Buttons are appropriate when it’s important for users to see all available options at once. This visibility helps users make informed decisions quickly without having to navigate through drop-down menus.

Immediate selection feedback

Use Radio Buttons when it’s beneficial to provide immediate feedback upon selection. This is useful in scenarios where the selection triggers immediate changes or updates in the UI.

Contextual relevance

When the context requires a single choice that directly impacts the user’s experience or the application’s behavior, Radio Buttons provide a clear and precise way to capture the user’s selection.

Don’t use for:

Multiple selections needed

Radio Buttons are designed for single selections from a group of options. They are not suitable when users need to select multiple options simultaneously. For such cases, checkboxes are more appropriate.

Dynamic and complex selections

In scenarios where the options are numerous, dynamically changing, or hierarchical, Radio Buttons can become unwieldy and clutter the interface. Drop-down menus or other advanced selection controls can better handle complex selections.

Infrequent or optional choices

When the selection is optional or infrequent, a checkbox might be more appropriate. Radio buttons imply that a choice must be made from the options displayed, thus, for optional selections, using a checkbox or a different control can reduce user confusion.

Behavior

Exclusive Selection

Exclusive selection means that selecting a Radio Button in a group automatically deselects any previously selected option in the same group. This ensures that the user can only select one option at a time, making Radio Buttons ideal for scenarios where a single choice is required. For example, when asking users to select their gender (Male, Female, Other), the use of Radio Buttons ensures that only one option can be chosen.

  1. Single Choice Enforcement: When a user selects a Radio Button, any other previously selected Radio Button in the same group is automatically deselected. This enforcement prevents multiple selections and ensures clarity in the user’s choice.
  2. Immediate Feedback: Upon selecting a Radio Button, the interface provides immediate visual feedback by filling in the chosen option. This instant response confirms the user’s action and clearly indicates the selected option.
