How to sync/hide certain folders on safari?

Hey everyone, I got a question. I made a folder on safari of private things I favortied, how do I stop that folder from syncing with my iphone? I dont want it on my iphone when I go into safari.

Also how could I hide it from the search on safari on my computer? Like lets say the link i favorited is facebook.com, if I am searching in the top bar and i type in "fa" then below it will pop up the link i favorited, in this case facebook.com would pop up. I how do I prevent this from hapening?

Thanks.
