UIKIT WP Integrator

No, your theme already has the UIKIT framework integrated

Yes, just uncheck addons from settings page of the plugin located under Settings -> UIKIT Integrator menu

Add this code inside functions.php of your theme:

add_theme_support( 'menus' ); if (function_exists('register_nav_menus')) { $locations = array( 'primary' => 'Primary Navigation' ); register_nav_menus( $locations ); } function nav_menu_item_parent_classing( $classes, $item ) { global $wpdb; $has_children = $wpdb -> get_var( "SELECT COUNT(meta_id) FROM {$wpdb->prefix}postmeta WHERE meta_key='_menu_item_menu_item_parent' AND meta_value='" . $item->ID . "'" ); if ( $has_children > 0 ) { array_push( $classes, "uk-parent" ); } return $classes; } add_filter( "nav_menu_css_class", "nav_menu_item_parent_classing", 10, 2 ); class Child_Wrap extends Walker_Nav_Menu { function start_lvl(&$output, $depth = 0, $args = array()) { $indent = str_repeat("\t", $depth); $output .= "\n$indent<div class=\"uk-dropdown uk-dropdown-navbar\"><ul class=\"uk-nav uk-nav-navbar\">\n"; } function end_lvl(&$output, $depth = 0, $args = array()) { $indent = str_repeat("\t", $depth); $output .= "$indent</ul></div>\n"; } }
