Conditional Logic in classifieds form - Adding a "Map" to the listing - Video in classifie

Hola

Is it possible to add conditional Logic to the form when people are completing their listing - as we are looking to advertise Horses and Equipment for sale around the world, I need to only display counties in the UK when UK is selected as the country, likewise States when USA is selected etc.

Map - Is it possible to add a map with a pin to the listings?

Video - I am trying to embed youtube videos to the listing posts ... is this possible as currently I just get the link and no video displaying?

Thanks guys
