How Can I Conditionally Apply Class Attributes in React?

Conditionally Apply Class Attributes in React

In React, it's common to show or hide elements based on props passed from parent components. To achieve this, you can conditionally apply CSS classes. However, a potential issue arises when utilizing the syntax {this.props.condition ? 'show' : 'hidden'} directly within a string.

To resolve this issue, move the curly braces outside of the string, as seen in this corrected example:

<div className={"btn-group pull-right " + (this.props.showBulkActions ? 'show' : 'hidden')}

This adjustment ensures the condition is evaluated before concatenating the class names. Note the space after "pull-right" to prevent accidentally creating the "pull-rightshow" class instead of the intended "pull-right show" class. Additionally, the parentheses are crucial for proper evaluation.
