Currently, the Kendo UI for Vue Native DropDownList doesn't have the valuePrimitive property which is available in the:

• Angular DropDownList - https://www.telerik.com/kendo-angular-ui/components/dropdowns/api/DropDownListComponent/#toc-valueprimitive 
• and the jQuery DropDownList - https://docs.telerik.com/kendo-ui/api/javascript/ui/dropdownlist/configuration/valueprimitive 

Providing such property for the Native Vue DropDownList will be useful in different use-case scenarios.
