In this article, you will learn how to add custom properties (check box options) to the SharePoint Framework web part.
In my previous article, I introduced the custom properties on SharePoint Framework (SPFx).
In my SPFx article series, you can learn about SPFx introduction, prerequisites, steps for setting up the environment, and developing and testing the web parts using the local environments.
In this sample, you will see how to add check box options to the SPFx web part properties pane. The web part will render the items of a list with multiple columns based on the checked items.
