Advanced properties provide additional functionality. They can be accessed by clicking on the "Advanced" Button in the bottom right corner of the widget designer.
Allow Quantity Selection
The Allow Quantity Selection property will add a numerical text box below the product selector. This will allow users to order multiple products.
Choose a Product
The Choose a Product selection box will allow you to select a single product imported from CRM.
Always Add to Cart
The Always Add to Cart checkbox will always add the product selected by this widget to the cart.
Select a Template - product selector
The Select a Template drop down list will allow you to select a template for your product to use with the option of creating a new template. If a template is selected, you will be given the additional option of editing the selected template.
Product Id Query String Name
The Product Id Query String Name advanced property will read in a query string parameter - which is defined in this advanced property - and use the value of that query string to select a product automatically. The value of the query string should be the GUID of a product.
