# aria-role
Elements with ARIA roles must use a valid, non-abstract ARIA role. A reference to role definitions can be found at [WAI-ARIA](https://www.w3.org/TR/wai-aria/#role_definitions) site.

## Rule details
This rule takes one optional object argument of type object:
```
{
"rules": {
"jsx-a11y/aria-role": [ 2, {
"ignoreNonDOM": true
}],
}
}
```
For the `ignoreNonDOM` option, this determines if developer created components are checked.
### Succeed
```jsx
<div role="button"></div> <!-- Good: "button" is a valid ARIA role -->
<div role={role}></div> <!-- Good: role is a variable & cannot be determined until runtime. -->
<div></div> <!-- Good: No ARIA role -->
<Foo role={role}></Foo> <!-- Good: ignoreNonDOM is set to true -->
```
### Fail
```jsx
<div role="datepicker"></div> <!-- Bad: "datepicker" is not an ARIA role -->
<div role="range"></div> <!-- Bad: "range" is an _abstract_ ARIA role -->
<div role=""></div> <!-- Bad: An empty ARIA role is not allowed -->
<Foo role={role}></Foo> <!-- Bad: ignoreNonDOM is set to false or not set -->
```
