# no-noninteractive-element-to-interactive-role

|
Non-interactive HTML elements indicate _content_ and _containers_ in the user interface. Non-interactive elements include `<main>`, `<area>`, `<h1>` (,`<h2>`, etc), `<img>`, `<li>`, `<ul>` and `<ol>`.
|
||
|
|
|
||
|
|
Interactive HTML elements indicate _controls_ in the user interface. Interactive elements include `<a href>`, `<button>`, `<input>`, `<select>`, `<textarea>`.
|
||
|
|
|
||
|
|
|
||
|
|
[WAI-ARIA roles](https://www.w3.org/TR/wai-aria-1.1/#usage_intro) should not be used to convert a non-interactive element to an interactive element. Interactive ARIA roles include `button`, `link`, `checkbox`, `menuitem`, `menuitemcheckbox`, `menuitemradio`, `option`, `radio`, `searchbox`, `switch` and `textbox`.

## How do I resolve this error?
|
||
|
|
|
||
|
|
### Case: This element should be a control, like a button
|
||
|
|
|
||
|
|
Put the control inside the non-interactive container element.
|
||
|
|
|
||
|
|
```
|
||
|
|
<li>
|
||
|
|
<div
|
||
|
|
role="button"
|
||
|
|
onClick={() => {}}
|
||
|
|
onKeyPress={() => {}}>
|
||
|
|
Save
|
||
|
|
</div>
|
||
|
|
</li>
|
||
|
|
```
|
||
|
|
|
||
|
|
Or wrap the content inside your interactive element.
|
||
|
|
|
||
|
|
```
|
||
|
|
<div
|
||
|
|
role="button"
|
||
|
|
onClick={() => {}}
|
||
|
|
onKeyPress={() => {}}
|
||
|
|
tabIndex="0">
|
||
|
|
<img src="some/file.png" alt="Save" />
|
||
|
|
</div>
|
||
|
|
```

## Rule details
|
||
|
|
|
||
|
|
The recommended options for this rule allow several common interactive roles to be applied to a non-interactive element. The options are provided as an object keyed by HTML element name; the value is an array of interactive roles that are allowed on the specified element.
|
||
|
|
|
||
|
|
```
|
||
|
|
{
|
||
|
|
'no-noninteractive-element-to-interactive-role': [
|
||
|
|
'error',
|
||
|
|
{
|
||
|
|
ul: ['listbox', 'menu', 'menubar', 'radiogroup', 'tablist', 'tree', 'treegrid'],
|
||
|
|
ol: ['listbox', 'menu', 'menubar', 'radiogroup', 'tablist', 'tree', 'treegrid'],
|
||
|
|
li: ['menuitem', 'option', 'row', 'tab', 'treeitem'],
|
||
|
|
table: ['grid'],
|
||
|
|
td: ['gridcell'],
|
||
|
|
},
|
||
|
|
]
|
||
|
|
}
|
||
|
|
```
|
||
|
|
|
||
|
|
Under the recommended options, the following code is valid. It would be invalid under the strict rules.
|
||
|
|
|
||
|
|
```
|
||
|
|
<ul role="menu" />
|
||
|
|
```
