Accessible and Responsive Tabbed Interface

This is an accessible tab solution based on guidelines documented by Heydon Pickering on the Inclusive Components Pattern Library

This was once part of a great list of patterns shared on the a11y project website's list of patterns. The A11Y project is now directing people to refer to the WAI-ARIA Authoring Practices. They offer a great checklist for UI testing.

A demo of this component is available in CodePen.

Please test your implementations with people that use assistive technologies.

JavaScript

Methods

a11yTabs.create('selector')

Creates a tabbed interface. Expects a string with the selector of the element that contains the tab-list and tab-panels.

a11yTabs.destroy(element)

Destroys the tabbed interface, removes Aria roles and attributes and event listeners.

Usage

// Create component
var tabCompponent = a11yTabs.create('[data-tab-component]);

// Destroy component
a11yTabs.destroy(tabComponent.element);

Options

Styling of the tab elments are based on ARIA roles. The default selector values can be overridden by passing in an options object to determine the selector values your component is using to structure the tabs.

{
  tabList: '.tab-list',
  tabItem: '.tab-item',
  tabLink: '.tab-link',
  tabPanel: '.tab-panel'
}
