# role-supports-aria-props
Enforce that elements with explicit or implicit roles defined contain only `aria-*` properties supported by that `role`. Many ARIA attributes (states and properties) can only be used on elements with particular roles. Some elements have implicit roles, such as `<a href="#" />`, which will resolve to `role="link"`.
## Rule details
This rule takes no arguments.
### Succeed
```jsx
<!-- Good: the radiogroup role does support the aria-required property -->
<ul role="radiogroup" aria-required aria-labelledby="foo">
<li tabIndex="-1" role="radio" aria-checked="false">Rainbow Trout</li>
<li tabIndex="-1" role="radio" aria-checked="false">Brook Trout</li>
<li tabIndex="0" role="radio" aria-checked="true">Lake Trout</li>
</ul>
```
### Fail
```jsx
<!-- Bad: the radio role does not support the aria-required property -->
<ul role="radiogroup" aria-labelledby="foo">
<li aria-required tabIndex="-1" role="radio" aria-checked="false">Rainbow Trout</li>
<li aria-required tabIndex="-1" role="radio" aria-checked="false">Brook Trout</li>
<li aria-required tabIndex="0" role="radio" aria-checked="true">Lake Trout</li>
</ul>
```
