I'd like to hide the top navigation (including Contact Us) or create a unique navigation, and hide the logo on a specific collection page and the product pages on that specific collection and I'd like to also have a different URL (another domain that we own) for the collection (functioning as redirect).
Here is the collection page: https://maccabiart.com/collections/sale
Is this possible?
It would need customization to implement this feature, Unfortunately, there is no simple solution otherwise I will be happy to help you.
I would suggest hiring a Shopify expert to assist you OR feel free to contact me.
