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

You can find one composition example below and more going to the demos.

<FormControl>
  <InputLabel htmlFor="my-input">Email address</InputLabel>
  <Input id="my-input" aria-describedby="my-helper-text" />
  <FormHelperText id="my-helper-text">We'll never share your email.</FormHelperText>
</FormControl>

⚠️ Only one Input 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't be shared.
