FormControl API
The API documentation of the FormControl React component. Learn more about the properties and the CSS customization points.
import FormControl from '@material-ui/core/FormControl';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 FormControl.
This context is used by the following components:
- FormLabel
- FormHelperText
- Input
- InputLabel
⚠️ Only one input can be used within a FormControl.
