Lists with Connectors

This creates a vertical list using repeaters, either with numbers or icons. If you prefer using numbers, create a shortcode to get the current row index first by pasting the following code in functions.php and using [ acf_repeater_index ] without the spaces.

/// Get row index for ACF repeaters
function acf_repeater_index() {
    while( have_rows('icon_list_repeater') ): the_row(); // Change this to the repeater's field name.
        return get_row_index();
    endwhile;
}
add_shortcode( 'acf_repeater_index', 'acf_repeater_index' );
