I have installed the zip file for the widget Progress Gauge and also imported in the local host. But in the widget panel in the mashup, the widget is not available. How can I resolve this?
Where do you get the Extension?
Is the extension imported successfully?
If the Extension is imported successfully without any errors, you can try to restart Thingworx and see if you can see the widget. If you still can't see the widget, I am afraid that it is related to the Extension itself or the Extension doesn't match your Thingworx version.
