How to import a widget
Any widget that was previously exported can be imported into Apex. This creates a full widget, including its properties and field selections, that existed when it was originally saved.
To import a widget:
1. In the web interface, click Configuration > Widget Library.
2. Click the import icon .
If you select a widget, this button becomes hidden. Click Discard to de-select the widget.
A file prompt appears in your web browser.
3. Locate a widget file (file extension .OAW) and upload it.
4. If the Import Conflict prompt appears, you must fix these the conflicts and click Finish Import.
 
You successfully imported a widget into Apex.
