Hi,
We do have an availability/property search widget which has a location drop down. Once selected the widget will only show properties that match the criteria chosen by a potential guest, and then once that property is selected it generally would take the guest to a page where they can book that property.
If this still isn't quite what you're looking for, I'd recommend reaching out to our helpdesk with more specific details as to what you're trying to accomplish and we'll see if we can work with you any.
