How do you conditionally apply class attributes in React?

Applying Class Attributes Conditionally in React

Issue

You're attempting to conditionally show or hide a button group based on a prop passed from a parent component. However, the conditional logic within the class attribute is causing the expected behavior.

Solution

To correctly apply class attributes conditionally in React, ensure that the curly braces enclosing the conditional logic are outside the string.

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

In the corrected code:

• The curly braces are outside the string, so the conditional logic is evaluated within the string.
• The parentheses around the conditional logic are necessary to ensure proper execution.
• A space is added after "pull-right" to avoid accidentally providing the class "pull-rightshow" instead of "pull-right show".

With these adjustments, the conditional class attributes will function as expected, showing or hiding the button group based on the value of the showBulkActions prop.
