I was just going through the React-bootstrap form what is the use of controlId is it similar to name we use in legacy form?

<form>

    <FormGroup

      controlId=formBasicText ---------------------->> what is the use?

      validationState={this.getValidationState()}

    >

      <ControlLabel>Working example with validation</ControlLabel>

      <FormControl

        type=text

        value={this.state.value}

        placeholder=Enter text

        onChange={this.handleChange}

      />

      <FormControl.Feedback />

      <HelpBlock>Validation is based on string length.</HelpBlock>

    </FormGroup>

  </form>
