Introduction

Power Apps, a low-code development platform by Microsoft, offers a variety of controls to create interactive applications. Among these is the Toggle control, which allows users to switch between two states - On and Off. In this article, we will explore the Toggle control in Power Apps and learn how to bind data from SharePoint, enhancing the functionality of your applications.

Benefits
