Yeah now its clear 🙂
Open your functions.php file and add this code if options page is not visible in WP menu
// register options page
if(function_exists('acf_add_options_page')) {
acf_add_options_page();
}
When create field group with field f.e.’portfolio_background’
When choose field group location -> Show this field group if [OPTIONS PAGE] is equal to [OPTIONS].
Inside archive-projects.php add
<?php the_field('portfolio_background', 'options');?>
That would be the way how to echo some field and control it if you don’t have page in WP menu.
