setTabNav("tab列表", "当前tab")

先来个例子

public function index($group = "tab1")
{
    $list_tab = [
        "tab1" => ["title" => "标题1", "url" => url("index", ["group" => "tab1"])],
        "tab2" => ["title" => "标题2", "url" => url("index", ["group" => "tab2"])],
    ];

    return ZBuilder::make("form")
        ->setTabNav($list_tab,  $group)
        ->fetch();
}

效果：

注意：此tab切换并非动态切换，而是跳转页面。

这样可以根据不同的接收到的group参数来分别显示不同的内容，比如：

public function index($group = "tab1")
{
    $list_tab = [
        "tab1" => ["title" => "标题1", "url" => url("index", ["group" => "tab1"])],
        "tab2" => ["title" => "标题2", "url" => url("index", ["group" => "tab2"])],
    ];
    
    switch ($group) {
    	case "tab1":
            return ZBuilder::make("form")
                ->setTabNav($list_tab,  $group)
                ->addText("name", "名称")
                ->fetch();
        	break;
        case "tab2":
        	return ZBuilder::make("form")
                ->setTabNav($list_tab,  $group)
                ->addTextarea("summary", "摘要")
                ->fetch();
        	break;
    }
}

两个页面如下：

tab1页面

tab2页面
