Closing any container when clicking outside of it

close_container.js

    $(document).mouseup(function(e) {
        let container = $(".js-postOptionsMenu"); //insert container selector, multiple selectors for different containers will work fine
        if (!container.is(e.target) && container.has(e.target).length === 0) {
            container.fadeOut();//you can replace .fadeOut() with any other way to hide your container
        }
    });
