In the world of web accessibility, it is essential to ensure that users with disabilities can properly interact with web applications. The Web Accessibility Initiative – Accessible Rich Internet Applications (WAI-ARIA) provides a set of guidelines to help developers create accessible web content.
One important attribute in WAI-ARIA is the aria-multiselectable attribute. This attribute allows developers to indicate whether multiple items within a user interface element can be selected simultaneously. In this blog post, we will explore the aria-multiselectable attribute and its usage.
The aria-multiselectable Attribute
The aria-multiselectable attribute is used to indicate whether multiple items within a user interface element can be selected at the same time. It is applicable to elements such as menus, lists, and grids.
The possible values for the aria-multiselectable attribute are:
false(default): Only a single item can be selected at a time.true: Multiple items can be selected simultaneously.
By properly setting the aria-multiselectable attribute, assistive technologies can provide accurate information to users with disabilities, indicating whether they can select multiple items or only one.
Usage Example
Let’s consider a scenario where we have a dropdown menu with multiple options, and we want to allow users to select multiple items simultaneously. We can use the aria-multiselectable attribute in combination with the role attribute to achieve this.
<div role="menu" aria-multiselectable="true">
<button role="menuitem" tabindex="0">Option 1</button>
<button role="menuitem" tabindex="-1">Option 2</button>
<button role="menuitem" tabindex="-1">Option 3</button>
</div>
In the above example, we set the aria-multiselectable attribute to "true" to indicate that multiple options can be selected simultaneously within the dropdown menu.
Conclusion
The aria-multiselectable attribute is a valuable tool in web accessibility, allowing developers to specify whether multiple items can be selected within a user interface element. By using this attribute correctly, we can ensure that users with disabilities have a seamless experience when interacting with web applications.
Remember to always refer to the WAI-ARIA documentation for proper usage guidelines and best practices.
