To create an options page, open up your current themes functions.php file and add the following code:
<?php
if( function_exists('acf_add_options_page') ) {
acf_add_options_page(array(
'page_title' => 'Theme General Settings',
'menu_title' => 'Theme Settings',
'menu_slug' => 'theme-general-settings',
'capability' => 'edit_posts',
'redirect' => false
));
}
?>
Without passing any parameters to this function, the default options page will be added to your wp-admin sidebar.
