This materials allow you to add user-friendly toggle (one or few) to the project.
To make it work you should copy all files from included archive Toggle.rar there:
(You'll have to create folder named Toggle manually)
After that go to the web-view of your project and add an extension object named Toggle.
(this should help https://help.qlik.com/en-US/qlikview-developer/November2017/Subsystems/Extensions/Content/extensions...)
Properties of the object will help you to customize your toggle.
Also you'll have to create some variables which will contain the condition of the toggle.
That's all. Hope it will be useful for you!
