How Can I Dynamically Add Classes to Static Class Names in JSX?

Dynamically Adding Classes to Manual Class Names in JSX

In JSX, we often need to dynamically add classes to elements based on certain conditions. This requires manipulating the className property to include both static and dynamic class names. Here's how to achieve this:

Using JavaScript Syntax

You can use normal JavaScript syntax to add dynamic classes to manual class names:

className={'wrapper searchDiv ' + this.state.something}

This will concatenate the static class names "wrapper" and "searchDiv" with the dynamic class name determined by the state property this.state.something.

Using String Templates

Alternatively, you can use string templates (ES6 template literals) with backticks:

className={`wrapper searchDiv ${this.state.something}`}

This syntax allows you to interpolate JavaScript expressions directly into the string, including dynamic class names.

Note:

Remember that anything enclosed in curly brackets in JSX is interpreted as JavaScript code. Hence, you can perform complex logic and manipulate strings as needed within the className attribute. However, you cannot combine JSX strings and curly brackets directly within attributes.
