Configure a Ucommerce picker as a property editor
With the integration for Umbraco 7, comes the ability to configure a Ucommerce picker as a property editor that allows you to select a catalog item from your items in Umbraco.

All that is required to do is to create a new Data Type in Umbraco and start using it for your generic properties on your document type.
Creating the Data Type
Data types can be created under the Developer section in Umbraco. Right click the Data Types folder and click Create. There's a few configuration options you need to consider which are elaborated below.

The property editor field should be "Ucommerce Picker", that will enable a selection from the Ucommerce tree. You will have two new options you need to select for your picker:
- Selector : Defines what node types that will be selectable. Right now, they are limited to Catalog entities (stores, catalogs, categories, products, or variants).
- Tree : Determines what section of the tree will be shown. Right now its limited to the catalog section with and without products.
You can now use your newly created Data Type to create new properties.
