Web map using url parameters

Description
This sample shows how to display a map from www.arcgis.com in a sample layout created using the Dojo layout widgets. This application allows application users to specify a web map id as a url parameter.
The template also contains a configuration section that allows the template developer to specify default values. If no url parameters are specified, the sample uses the hardcoded values from within the application.
- webmap: Use this to specify the item id for the ArcGIS.com map.
- title: Specify the item id for the ArcGIS.com map. This will be overwritten if a webmap id is specified via url.
- subtitle: Enter a default subtitle for the map. If nothing is specified the web map snippet is used as the subtitle.
- sharingurl: Enter a url to your organizations content - by default this is http://www.arcgis.com/sharing/rest/content/items.
For additional information on working with the Dojo layout widgets see the Build Application Layouts help document.
