The API documentation of the FormControl React component.

Provides context such as filled/focused/error/required for form inputs. Relying on the context provides high flexibilty 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


Name Type Default Description
children node The contents of the form control.
classes object Override or extend the styles applied to the component. See CSS API below for more details.
component union: string |
 func |
'div' The component used for the root node. Either a string to use a DOM element or a component.
disabled bool false If true, the label, input and helper text should be displayed in a disabled state.
error bool false If true, the label should be displayed in an error state.
fullWidth bool false If true, the component will take up the full width of its container.
margin enum: 'none' |
 'dense' |
'none' If dense or normal, will adjust vertical spacing of this and contained components.
required bool false If true, the label will indicate that the input is required.

Any other properties supplied will be spread to the root element (native element).


You can override all the class names injected by Material-UI thanks to the classes property. This property accepts the following keys:

Name Description
root Styles applied to the root element.
marginNormal Styles applied to the root element if margin="normal".
marginDense Styles applied to the root element if margin="dense".
fullWidth Styles applied to the root element if fullWidth={true}.

Have a look at overriding with classes section and the implementation of the component for more detail.

If using the overrides key of the theme as documented here, you need to use the following style sheet name: MuiFormControl.
