How can I set an static outlined div similar to Material-UI's outlined textfield?

问题

I want wrap some TextFields in a outlined container and I found this answer. This work as i want:

But when I click in an inside textfield all the texfields focused:

This is my code:

import React from "react";
import ReactDOM from "react-dom";

import OutlinedDiv from "./OutlinedDiv";
import TextField from "@material-ui/core/TextField";
import Grid from "@material-ui/core/Grid";

function App() {
  return (
    <div className="App">
      <OutlinedDiv label="DIV">
        <Grid container justify="center" alignItems="center" spacing={3}>
          <Grid item sm={4} xs={12}>
            <TextField label="Text1" variant="outlined" />
          </Grid>
          <Grid item sm={4} xs={12}>
            <TextField label="Text2" variant="outlined" />
          </Grid>
          <Grid item sm={4} xs={12}>
            <TextField label="Text3" variant="outlined" />
          </Grid>
          <Grid item sm={4} xs={12}>
            <TextField label="Text4" variant="outlined" />
          </Grid>
          <Grid item sm={4} xs={12}>
            <TextField label="Text5" variant="outlined" />
          </Grid>
          <Grid item sm={4} xs={12}>
            <TextField label="Text6" variant="outlined" />
          </Grid>
        </Grid>
      </OutlinedDiv>
    </div>
  );
}

const rootElement = document.getElementById("root");
ReactDOM.render(<App />, rootElement);

How I can achive this style and when click in an inside component only focus the selected component?

A response with another approach and the similar solution for outlined div is welcome.

Thanks in advance.

Below is an approach that does not leverage TextField or FormControl and thus can be safely used to wrap other inputs. This copies some styles from OutlinedInput and the InputLabel styles applied when within a FormControl.

import React from "react";
import ReactDOM from "react-dom";
import InputLabel from "@material-ui/core/InputLabel";
import NotchedOutline from "@material-ui/core/OutlinedInput/NotchedOutline";
import { withStyles } from "@material-ui/core/styles";

const styles = {
  root: {
    position: "relative"
  },
  content: {
    padding: "18.5px 14px"
  },
  inputLabel: {
    position: "absolute",
    left: 0,
    top: 0,
    // slight alteration to spec spacing to match visual spec result
    transform: "translate(0, 24px) scale(1)"
  }
};

const LabelledOutline = ({ classes, id, label, children }) => {
  const [labelWidth, setLabelWidth] = React.useState(0);
  const labelRef = React.useRef(null);
  React.useEffect(() => {
    const labelNode = ReactDOM.findDOMNode(labelRef.current);
    setLabelWidth(labelNode != null ? labelNode.offsetWidth : 0);
  }, [label]);

  return (
    <div style={{ position: "relative", marginTop: "8px" }}>
      <InputLabel
        ref={labelRef}
        htmlFor={id}
        variant="outlined"
        className={classes.inputLabel}
        shrink
      >
        {label}
      </InputLabel>
      <div className={classes.root}>
        <div id={id} className={classes.content}>
          {children}
          <NotchedOutline notched labelWidth={labelWidth} />
        </div>
      </div>
    </div>
  );
};
export default withStyles(styles)(LabelledOutline);
