Hi Friends 👋,

Welcome To aHoisting!

To change height and width of dropdown in react js, you can set width: 250px; and height: 40px; in .custom-dropdown. It will change height and width of dropdown in react js.

Today, I am going to show you, how to change height and width of dropdown in react js.

Table of contents

  • Install and create a new React app.
  • Import react component.
  • Create a Component.

Let’s start with the first step.

Step 1: Install and create a new React app.

First you have to install the React project. You should use create-react-app command to create a new React project.

npx create-react-app my-app
cd my-app
npm start

Step 2: Import react component.

After installing, you have to import your React component.

import React from 'react';
import './App.css';

Step 3: Create a Component.

You can use className="custom-dropdown" to change height and width of dropdown in react js.

<select className="custom-dropdown">
  <option value="option1">Option 1</option>
  <option value="option2">Option 2</option>
  <option value="option3">Option 3</option>
</select>

Change height and width of dropdown example.

The below code is an example of a React. You have to import './App.css' and use width: 250px; and height: 40px; in .custom-dropdown to change height and width of dropdown in react js.

App.js

import React from 'react';
import './App.css';

function App() {
  return (
    <select className="custom-dropdown">
      <option value="option1">Option 1</option>
      <option value="option2">Option 2</option>
      <option value="option3">Option 3</option>
    </select>
  );
}

export default App;

App.css

.custom-dropdown {
  width: 250px;  /* Set the width of the dropdown */
  height: 40px;  /* Set the height of the dropdown */
  padding: 5px;  /* Optional: add padding */
}

In the above code example, I have used the width: 250px; and height: 40px; to change height and width of dropdown in react js.

Check the output of the above code.
