Open an existing analytic application, or create a new one.

To use a custom widget in your application, the ‘Optimized Design Experience’ Mode needs to be enabled.

By creating the story, you need to select “Optimized Design Experience”.

If you want to implement Widget in your existing story, which was created in ‘Classic Design Experience’, you should add the following changes. Save the application, then by saving select ‘Convert to Optimized Design Experience’.

Once this is done, you will be able to place the Wiget in your application.

To do so, from the Insert tab at the top, click on the ‘+’, then go the ‘Custom Widgets’, and select the Widget you previously imported.
