Hi, Can I add Countries, Year wise Filter in Posts Grids?
Welcome to our forum.
I am not sure you want filterable menu by Countries, Year or query post by meta field Countries, Year
If you are looking for query post by meta field countries this is possible, also if you want to query post by year is possible.
And if you want to display country, year as filterable grid filter also possible via custom filter but you will need to extra coding. i can help you.
Please note meta field query and filterable grid feature only available in pro version.
