Sometimes, we want to create a dynamic drop down list with React Bootstrap.

In this article, we’ll look at how to create a dynamic drop down list with React Bootstrap.

How to create a dynamic drop down list with React Bootstrap?

To create a dynamic drop down list with React Bootstrap, we can call the option array’s map method to return the option element for each option in the array.

For instance, we write:

import React, { useState } from "react";
import "bootstrap/dist/css/bootstrap.min.css";
import { Form } from "react-bootstrap";

const options = [
  { name: "One", id: 1 },
  { name: "Two", id: 2 },
  { name: "Three", id: 3 },
  { name: "four", id: 4 }
];

export default function App() {
  const [val, setVal] = useState();
  console.log(val);

  return (
    <Form.Select value={val} onChange={(e) => setVal(e.target.value)}>
      {options.map((o) => {
        const { name, id } = o;
        return <option value={id}>{name}</option>;
      })}
    </Form.Select>
  );
}

We call options.map with a callback that returns the option element by setting the value prop to id and the text content to name.

Now we should see the options One, Two, Three and Four available in the drop down.

We also set the value prop of Form.Select to val and the onChange prop to a function that calls setVal with e.target.value to set val to the selected option’s value attribute value.

Conclusion

To create a dynamic drop down list with React Bootstrap, we can call the option array’s map method to return the option element for each option in the array.
