In the world of web accessibility, it’s important to provide a robust and inclusive user experience for all individuals, including those with disabilities. One key aspect of web accessibility is the proper use of WAI-ARIA (Web Accessibility Initiative - Accessible Rich Internet Applications) attributes. In this blog post, we will explore the aria-selected
attribute and its significance in enhancing the accessibility of web applications.

What is the aria-selected
attribute?
The aria-selected
attribute is a WAI-ARIA attribute that is used to indicate the current selection state of an element, such as a tab, a list item, or a checkbox. It informs assistive technologies, such as screen readers, about the active or selected item, allowing users to navigate and interact with the application effectively.
The aria-selected
attribute can be applied to different HTML elements, including but not limited to <button>
, <li>
, <option>
, <input>
, and <div>
, depending on the context and purpose of the selection.
Why is the aria-selected
attribute important?
By using the aria-selected
attribute correctly, we can improve the accessibility of web applications by providing clear feedback and visual cues to users. Here are a few reasons why the aria-selected
attribute is important:
-
Enhanced navigation: Assistive technologies can understand the current selection state, allowing users to navigate through selectable items more efficiently. For example, screen reader users can easily identify and interact with the selected tab within a tabbed interface.
-
Clear feedback: When an item is selected, providing the
aria-selected
attribute communicates its active state to users, regardless of their abilities. This helps users maintain better orientation and stay informed about their current selection. -
Keyboard accessibility: When implementing keyboard navigation, using the
aria-selected
attribute ensures that users can easily identify and interact with selectable elements. Users can use the keyboard to navigate between items, and thearia-selected
attribute indicates the currently active item.
How to use the aria-selected
attribute
To use the aria-selected
attribute, you need to set its value appropriately based on the current selection state. The aria-selected
attribute accepts one of three possible values:
"true"
: Indicates that the item is selected."false"
: Indicates that the item is not selected."undefined"
or not provided: Indicates that the selection state is not known or not applicable.
Examples of aria-selected
attribute usage
Example 1: Tabs
<div role="tablist">
<button role="tab" aria-selected="true">Tab 1</button>
<button role="tab" aria-selected="false">Tab 2</button>
<button role="tab" aria-selected="false">Tab 3</button>
</div>
In this example, the aria-selected
attribute is used to denote the currently selected tab. The first tab has the attribute set to "true"
, while the other tabs have it set to "false"
.
Example 2: List items
<ul role="listbox">
<li role="option" aria-selected="true">Item 1</li>
<li role="option" aria-selected="false">Item 2</li>
<li role="option" aria-selected="false">Item 3</li>
</ul>
In this example, the aria-selected
attribute is used to indicate the selected item within a list. The first list item has the attribute set to "true"
, while the rest have it set to "false"
.
Conclusion
The aria-selected
attribute plays a crucial role in enhancing the accessibility of web applications by providing important information about the current selection state. By using this attribute appropriately, we can create a more inclusive user experience for individuals with disabilities. When working on web development projects, remember to consider and implement the aria-selected
attribute whenever there’s a need to indicate selection within your user interface.
