Hi there, i just want to share the code of what the subject line says. The pages to appear in the menu have a custom field "in_main_menu" of type checkbox checked. The item <li>s of the actually shown page and in the direttissima upwards - except home - get the class "current". The item <ul>s of submenus get the class "submenu". This is basically Ryans Code from here run through a meatgrinder. I hope useful for any beginners like me looking for a solution to a similar problem. Any improvement welcome! Now the code: /** * A recursive menu containing home. (It is added to the list of menu items while $level =1). * In order to be included, a page must have a custom field "in_main_menu" of type "checkbox", * and the latter has to be checked. * All submenu <ul>s get class "submenu". * All <li>s in the direttissima upwards of the page shown - except home - get the class "current". * Takes $root out of the recursion in order to not have all pages twice. * All menu items, that have children, do not have a link to their content, but act merely as switches. * You can switch this behaviour off by replacing * * $href = ( $item == $root || !$item->numChildren ? "$item->url" : "#" ); * * with * * $href = $item->url; * * Or you can make it conditional by querying a second custom field "has_own_page", e.g. * * $href = ( $item == $root || !$item->numChildren || $item->has_own_page ? "$item->url" : "#" ); * * Intended to be used without arguments, i.e. "selectiveMenu();" , i.e. always starting with site root. */ function selectiveMenu(Page $root = null) { $shownPage = wire('page'); if(is_null($root)) $root = wire('pages')->get('/'); $level = count($root->parents); $ul_class_string = (($level > 0) ? "class='submenu'" : ""); $out = "\n<ul {$ul_class_string}>"; $parents = $shownPage->parents; $items = $root->children; if ($level == 0) $items->prepend($root); foreach( $items as $item) { if ($item->in_main_menu) { $s = ''; $li_class_string = ( ( $parents->has($item) && $item !== $root ) || $item === $shownPage ? "class='current'" : "" ); if($item->numChildren && $item !== $root) { $s = str_replace("\n", "\n\t\t", selectiveMenu($item)); } $href = ( $item == $root || !$item->numChildren ? "$item->url" : "#" ); $out .= "\n\t<li {$li_class_string}>\n\t\t<a href='{$href}'>{$item->title}</a>$s\n\t</li>"; } } $out .= "\n</ul>"; return $out; }- 1 reply
