- No and it is not planned.
- From my personal testing, I think that myCRED can hook into several key components of Directories Pro – for example, when someone adds a new listing or review.
Is it possible to limit certain filters only to specific categories?
No, but this is planned for a future version, probably 1.2.x.
Can one setup bidirectional reference types? For example, so that a business is related to its products and this causes the products to also be associated with the business?
This is not currently possible, but is planned for 1.2.
Under what circumstances can someone claim a listing?
Only if the listing is not already claimed by someone else. See documentation.
Is it possible to add a canonical tag for categories?
There is no built-in functionality using Directories Pro, but this should be accomplishable using an SEO plugin.
