Usage

Choosing the right component for the task

When deciding which component to use, consider the number of options available to the user. The total number of options will determine which component is right for the task:

  • 2 - 5 options: Use Radio button when there are only a few options that can all be exposed at once.
  • 6 - 15 options: Use Select for a limited number of options.
  • 16 - 100 options: Use Combo box, which combines a select with typeahead functionality for easier selection.
  • 101+ options: Use Search input with typeahead to help users quickly find the right option from a large set.

Exceptions to consider when choosing a component

In some cases, exceptions may be considered when choosing the right component:

  • When the options are known and memorable. Use Combo box if the user will know what to expect as options in the dropdown, such as a list of countries or states. See the USWDS address pattern.
  • When the radio button labels are long or radio tiles contain descriptive text. Long labels within a dropdown might make it difficult to read and select an option. Radio tiles often include descriptive text that cannot be used in a dropdown. In these cases, Radio button may be the better choice.

Contact the Design System team via #platform-design-system for help if you have other use cases that may be considered exceptions.

Events

Name Description component-library-analytics The event used to track usage of the component. This is emitted when an option is selected and enableAnalytics is true. vaKeyDown The event attached to select's onkeydown vaSelect The event emitted when the selected value changes vaSelectBlur The event emitted when the select element is blurred

Native Events

  • The native onKeyDown event is available on this component. It can be used by adding the event handler to your component and it will then listen to the event and respond accordingly when the event fires.

Accessibility considerations

Privacy guidance

When Personally Identifiable Information (PII) or Protected Health Information (PHI) is an option in a selection list, selections can’t be tracked in analytics or passed into other page elements that may be tracked.

  • Analytics tracking for this component must remain off if the options contain PII or PHI.
  • Selections can’t be utilized in elements on follow-on or related pages, such as a parameter or title tag.

Example: A form application asks the user to select a health condition from a dropdown list. Details about a person’s health conditions are considered PHI. The option selected can be stored in our data systems, but the selection can’t be tracked in analytics or utilized as part of the title tag in the next page.
