The new product chooser currently displays 4 columns/layouts for connectors with connections, categories, products, preview.

The chooser can be used for selection of connection or category. In this case doesn't make sense to display products and preview columns. Provide possibility to configure to display only:

• connector column
• connector and categories column 

If user configure connection in a product chooser configuration, don't display connector column. 

If only one connector with one connection is configured in magnolia instance, don't display connector column.

Notes 

we want to display connector/connection in the Chooser dialog - rather than showing an empty dialog

• When we have one connector, one connection enabled; for the dialog
• When we have one connector, one connection configured, within the commerce app
