Here is a layer list widget provided by WebApp Builder Beta.
It is not always easy to turn on and off on mobile devices.
Is there a way to enlarge a checkbox?
Or can I have a layer turned on or off by touching layer name?
I appreciate your advice.
You might want to post WAB questions in the The specified item was not found. group. You can definitely modify the LayerList widgets code to handle the layer name click. Have you already reported this mobile issue in the Beta program?
I will post this question to Web AppBuilder for ArcGIS group.
