ARIA: list role
The ARIA list
role can be used to identify a list of items. It is normally used in conjunction with the listitem
role, which is used to identify a list item contained inside the list.
html
<div role="list">
<div role="listitem">List item 1</div>
<div role="listitem">List item 2</div>
<div role="listitem">List item 3</div>
</div>
Description
Any content that consists of an outer container with a list of elements inside it can be identified to assistive technologies using the list
and listitem
containers respectively. A list
must have one or more listitem
children, or, alternatively, have one or more group
s as children, with each group
having one or more listitem
s as children.
There are no hard and fast rules about which elements you should use to mark up the list and list items, but you should make sure that the list items make sense in the context of a list, e.g. a shopping list, recipe steps, driving directions.
Note: Best practices dictate using the appropriate semantic HTML elements over ARIA roles to mark up lists and listitems — <ul>
, <ol>
and <li>
. See Best practices for a full example.
Associated WAI-ARIA Roles, States, and Properties
listitem
role-
A single item in a list or directory. Elements with role listitem can only be found in an element with the role
list
orgroup
. group
role-
A collection of related objects, limited to list items when nested in a list, not important enough to have their own place in a page's table of contents.
Best practices
Only use role="list"
and role="listitem"
if you have to — for example if you don't have control over your HTML but are able to improve accessibility dynamically after the fact with JavaScript.
Unlike the HTML <ol>
and <ul>
, the ARIA list
roles doesn't distinguish between ordered and unordered lists. If at all possible, you should use the appropriate semantic HTML elements to mark up a list (<ol>
and <ul>
) and list items (<li>
). For example, our above example should be rewritten as follows:
html
<ul>
<li>List item 1</li>
<li>List item 2</li>
<li>List item 3</li>
</ul>
or use an ordered list if the order of the list items matters:
html
<ol>
<li>List item 1</li>
<li>List item 2</li>
<li>List item 3</li>
</ol>
Note: The ARIA list
/ listitem
roles don't distinguish between ordered and unordered lists.
As an aside, note that if you are using the semantic HTML elements of <ol>
or <ul>
and apply a role of presentation
, each child <li>
element inherits the presentation
role because ARIA requires the listitem
elements to have the parent list
element. So, the <li>
elements are not exposed to assistive technologies, but elements contained inside of those <li>
elements, including nested lists, are visible to assistive technologies.
