Firebase – Can't change the value inside input

I’m trying to change the values inside inputs. I got those values from the db.
But it doesn’t allow me to type or edit the value.
I’ve added an handleInputChange function to put inside onChange inside each input tag but it didn’t work.
I need those values to be inside inputs at the beginning and disappear after the user starts typing.

I thought about ref={ref} and defaultValue, but I don’t know how I’ll get updated values than in order to send it back to the db.

EditFeedbackPage.js

    const EditFeedbackPage = () => {
    
        const initialState = {
            category: "All",

            detail: "",
            id: nanoid(),
            createdAt: Timestamp.now().toDate(),
            status: "Suggestion",
            title: "",
            upVotesCount: []
        }
    
        const [state, setState] = useState(initialState);
        const { feedback } = useSelector((state) => state.data);
    
        const { category, detail, title, status } = feedback;
        console.log(feedback)

    use the state value in the title

      <input
          type="text"
          name='title'
          value={state.title}
          onChange={handleInputChange}
  />

    And assign useSelector value to initial state

        const { feedback } = useSelector((state) => state.data);

    const { category, detail, title, status } = feedback;
    console.log(feedback)
   
    const initialState = {
        category: "All",
        comments: [],
        detail: "",
        id: nanoid(),
        createdAt: Timestamp.now().toDate(),
        status: "Suggestion",
        title,
        upVotesCount: []
    }

    const [state, setState] = useState(initialState);

    Depending on your data structure, you can give your inputs a name & let the other state data same and update only one input.

    import { Container, TextField, Stack, MenuItem, Button } from "@mui/material";
import { useState } from "react";
import { v4 as uuidV4 } from "uuid";

const EditFeedbackPage = () => {
  const initialState = {
    category: "All",
    comments: [],
    detail: "Test",
    id: uuidV4(),
    createdAt: new Date(),
    status: "Suggestion",
    title: "",
    upVotesCount: []
  };

  const [state, setState] = useState(initialState);

  const handleInputChange = (event) => {
    const { name, value } = event.target;
    setState({ ...state, [name]: value });
  };

  const handleSubmit = (event) => {
    event.preventDefault();
    alert(JSON.stringify(state, null, 2));
  };

  return (
    <Container
      sx={{
        mt: 2
      }}
    >
      <Stack spacing={2}>
        <TextField
          size="small"
          name="title"
          value={state.title}
          onChange={handleInputChange}
          label="Add a short, descriptive headline"
        />
        <TextField
          select
          size="small"
          name="category"
          value={state.category}
          onChange={handleInputChange}
          label="Change a category for your feedback"
        >
          <MenuItem value="All">All</MenuItem>
          <MenuItem value="UI">UI</MenuItem>
          <MenuItem value="UX">UX</MenuItem>
          <MenuItem value="Enhancement">Enhancement</MenuItem>
          <MenuItem value="Bug">Bug</MenuItem>
          <MenuItem value="Feature">Feature</MenuItem>
        </TextField>
        <TextField
          select
          size="small"
          name="status"
          id="status"
          value={state.status}
          onChange={handleInputChange}
          label="Change feedback status"
        >
          <MenuItem value="Suggestion">Suggestion</MenuItem>
          <MenuItem value="Planned">Planned</MenuItem>
          <MenuItem value="In-Progress">In-Progress</MenuItem>
          <MenuItem value="Live">Live</MenuItem>
        </TextField>
        <TextField
          multiline
          rows={4}
          size="small"
          name="detail"
          value={state.detail}
          onChange={handleInputChange}
          label="Include any specific comments on what should be improved, added, etc."
        />
      </Stack>
      <Button
        sx={{
          mt: 2
        }}
        onClick={handleSubmit}
      >
        Submit
      </Button>
    </Container>
  );
};

export default EditFeedbackPage;
