Automatically display the in-panel widget window in Web AppBuilder for ArcGIS

Summary

In Web AppBuilder for ArcGIS, the in-panel widget can be set to automatically start upon loading the web map. However, by default, even if the in-panel widget is started, it is required to click the widget to display the Legend window. In the Web AppBuilder for ArcGIS widgets configurations, each in-panel widget contains a Boolean property, openAtStart, which is set as false by default. For more information about in-panel and off-panel widgets, refer to the following web help document, Web AppBuilder for ArcGIS (Developer Edition): In-panel and off-panel widgets.

This behavior can be altered by modifying the openAtStart property in the app config.json file.

Procedure

1. Open the app config.json file in the server\apps\selected app folder using a text editor, (for example, Notepad or Notepad++).
2. Search for the desired widget in the config.json file to locate a specific code segment.
3. Modify the "openAtStart" section to 'true'. The final code may vary depending on the versions used:

"widgets:[ ]") "widgets":[ 
{ 
"uri":"widgets/Legend/Widget", 
"version":"4.3", 
"openAtStart": true, 
}]
