Show or Hide Element in React

React is a popular JavaScript library used for building user interfaces. One common task in React is showing or hiding elements based on certain conditions. In this blog post, we will explore different ways to show or hide elements in React.

Using Conditional Rendering

Conditional rendering is a powerful feature in React that allows you to render different components or elements based on certain conditions. You can use conditional rendering to show or hide elements in React.

Here’s an example of how you can use conditional rendering to show or hide an element based on a boolean value:

{`import React, { useState } from 'react';

function App() {
  const [showElement, setShowElement] = useState(true);

  const toggleElement = () => {
    setShowElement(!showElement);
  };

  return (
    

      Toggle Element
      {showElement && 
This element is shown when showElement is true.
}
    
  );
}

export default App;`}

In the above example, we use the useState hook to create a boolean state variable called showElement. We then toggle the value of showElement when the button is clicked using the toggleElement function. The element is only rendered when showElement is true.

Using CSS Classes

Another way to show or hide elements in React is by using CSS classes. You can define different CSS classes to control the visibility of elements and toggle between them based on certain conditions.

Here’s an example of how you can use CSS classes to show or hide an element:

{`import React, { useState } from 'react';
import './App.css';

function App() {
  const [showElement, setShowElement] = useState(true);

  const toggleElement = () => {
    setShowElement(!showElement);
  };

  return (
    

      Toggle Element
      

        This element is shown when showElement is true.
      
    
  );
}

export default App;`}

In the above example, we define two CSS classes, ‘visible’ and ‘hidden’, in the App.css file. The ‘visible’ class sets the display property to ‘block’ and the ‘hidden’ class sets the display property to ‘none’. We then conditionally apply these classes to the element based on the value of showElement.

These are two common ways to show or hide elements in React. You can choose the approach that best suits your needs and the complexity of your application.

Happy coding!
