I am trying to use nervgh/angular-file-upload to show image preview on canvas when click on upload file button. I have an angular app, where the controller is defined in the body tag. I have three parts/sections of the app which require a choose file button each having a canvas to preview. So all the three come under the same controller.
How should I try and achieve this.
I did it for one section and it worked perfectly. Now I am confused If I need to add new directive with new controller for the next one.
