State class applied to {{nodeName}} if {{conditions}}.

Provides context such as filled/focused/error/required for form inputs.
Relying on the context provides high flexibility and ensures that the state always stays
consistent across the children of the <code>FormControl</code>.
This context is used by the following components:
<ul>
<li>FormLabel</li>
<li>FormHelperText</li>
<li>Input</li>
<li>InputLabel</li>
</ul>
You can find one composition example below and more going to <a href="https://mui.com/material-ui/react-text-field/#components">the demos</a>.
<div class="MuiCode-root"><pre><code class="language-jsx">&lt;FormControl>
 &lt;InputLabel htmlFor="my-input">Email address&lt;/InputLabel>
 &lt;Input id="my-input" aria-describedby="my-helper-text" />
 &lt;FormHelperText id="my-helper-text">We'll never share your email.&lt;/FormHelperText>
&lt;/FormControl>
</code></pre><button data-ga-event-category="code" data-ga-event-action="copy-click" aria-label="Copy the code" class="MuiCode-copy">CopyCopied(or $keyC)</button></div>
⚠️ Only one <code>Input</code> can be used within a FormControl because it create visual inconsistencies.
For instance, only one input can be focused at the same time, the state shouldn&#39;t be shared.

If <code>true</code>, the label, input and helper text should be displayed in a disabled state.

If <code>true</code>, the label is displayed in an error state.

Callback fired when the form element&#39;s value is modified.

If <code>true</code>, the label will indicate that the <code>input</code> is required.
