Public Item Selector AKA Public Display Categories
Introduction
Public Display Categories (PDC) in Wheelhouse offer an effective way to organize and present items, be they configured or non-configured, to users. This system ensures that users experience a seamless and intuitive product selection process.

Setting Up Public Display Categories:
- Initialize the ItemType:
 
Verify that the ItemTypePublicDisplayCategoryis available, or create it.
- Creating the Root:
 
The hierarchy starts with an Item named_ROOT_PDC_, with its ItemType set to PublicDisplayCategory. This acts as the root or parent for the entire hierarchy. If the item doesn't exist, create it.
- Understanding Hierarchies:
 
Product categories can often be set in hierarchies, where main categories have sub-categories. For instance, 'Electronics' can be a main category with 'Mobile Phones', 'Laptops', and 'Audio Devices' as sub-categories.
- Bill of Materials (BOM):
 
The display structure is determined by the BOM of the _ROOT_PDC_. Any component item in the BOM with an ItemType PublicDisplayCategory will be showcased as a PDC. The PDC BOM may be edited using the Item Designer as pictured.

- Creating a New Category:
 
- If an item exists for the PDC, drag it from the items list into the desired BOM location.
 - If the item doesn't exist, create a new item with ItemType=PublicDisplayCategory. This can be accomplished using the 3-dot menu in the Item Designer.
 
- Assigning Products to Categories:
 
- From the list of items on the left, drag the Product into the correct location in the BOM tree.
 
- Rearranging Display Order:
 
- In the Item Designer, drag and drop categories to rearrange their order. If the category is nested under another category, you can remove it and re-add it from the item list on the left.
 
- DisplayName:
 
- The 
DisplayNameof a PDC is showcased beneath its image. - For PDCs without a
DisplayName, only the image is displayed. - If an image is absent, the system defaults to showing either the 
DisplayNameor, if that isn't available, theName. 
Usage:
- Accessing PDC Selector:
 
The PDC selector becomes immediately visible upon selecting +Add Item in Order Management.
- External User Settings:
 
The setting labeled "Public Item Selector" governs the visibility of the PDC to external users:
- Search: The PDC is hidden from external users.
 - Browse & Search/Browse: Exposes the PDC to external users.

 
Best Practices:
- Consistency: Ensure that products are categorized consistently to avoid confusion.
 - Review Periodically: Market trends change. Regularly review your categories to ensure they still align with your product offerings and customer expectations.
 - Use Clear Names: Category names should be intuitive and descriptive, helping users understand what to expect.
 - Image Consistency: To maintain a professional appearance, use images of consistent sizes.
 - ActiveThru Date: If the 
_ROOT_PDC_item lacks an active through (ActiveThru) date or if there are no active items, the PDC system will not function as intended. 
Conclusion:
The Public Display Categories in Wheelhouse play a pivotal role in streamlining the item selection process, both for internal and external users. Proper setup and management guarantee a user-friendly experience and efficient order management.
