Add Search by country to woocommerce multistore (Dokan)

I have a running wordpress/woocommerce multi-store with Dokan plugin. I need someone to implement a custom search by country field. How the current site work. - Sellers can register on my website and start selling. (From any country) - For this I use the Dokan multi-store plugin - I need to implement a section where buyers(visitors) can select their country and find products. - Intended implementation need to have one of the below process Option 1 (Preffered) `````````````` --- select the country from a drop down menu on the navigation bar (menu bar) --- use will be take to wordpress search result page with products filtered from origin country (based Dokan sellers origin country) --- That's all. Dead simple if you know what I'm talking about Option 2 `````````````` --- User select the search products by country option in navigation bar ---- User is taken to a page with a drop down field to select the country ---- Upon selection of country, products are filtered on the same page
