Same as: jsx-a11y/label-has-associated-control

Enforce that a label element or component has a text label and an associated input.

An “input” is considered one of the following elements: input, meter, output, progress, select or textarea.

There are two supported ways to associate a label with an input:

Wrapping an input in a label element.
Adding a for attribute (or htmlFor in React) to a label and assigning it a DOM ID string associated with an input on the page.

This rule checks that any label element (or an indicated custom component that will output a label element) meets one of these conditions:

Wraps an input element (or an indicated custom component that will output an input element)
Has a for or htmlFor attribute and that the label element/component has accessible text content.

Valid

<label for="js_id" aria-label="A label" />;
<label for="js_id" aria-labelledby="A label" />;

Options

The rule supports the following options:

inputComponents - An array of component names that should be considered the same as an input element.
labelAttributes - An array of attributes that should be treated as the label accessible text content.
labelComponents - An array of component names that should be considered the same as a label element.

Both options inputComponents and labelComponents don’t have support for namespace components (e.g. <Control.Input>).
