How To: Change the resolution setting for switching to mobile view in Web AppBuilder for ArcGIS (Developer Edition)


With Web AppBuilder for ArcGIS, apps are designed to be responsive to various screen sizes. When either dimension (height or width) of the viewport reaches a threshold of 600 pixels, the interface changes. This affects widgets, popups, and other features. On small laptop screens, the application can be set to stay in desktop mode when below the default size threshold.

One option is to use the mobileBreakPoint URL parameter, for example:

 http://<your portal url>/apps/webappviewer/index.html?mobileBreakPoint=300
See the following Web Help topic: Use URL parameters
If this is not option, the solution below provides the same functionality by default.
