删除导航中烦人的可折叠滚动条

Question

我似乎无法取出位于我的可折叠引导程序中导航链接下方的此烦人的水平滚动条。我尝试了“最大宽度：100％；溢出-x：隐藏；”在导航栏的div容器中，“ margin：0;”在body标签中，但什么也没发生，问题仍然存在。

这个问题也只出现在我的标题导航栏中，并且仅在调整窗口大小时出现可折叠显示。

HTML：

Try-
Add in controller function-

$categoryList = Category::getCategories();

and assign the variable in smarty.

$this->smarty->assign(array(
'displayCategoryList' => $categoryList,
                ));
Add in tpl file-

{$displayCategoryList|@print_r}

CSS：

      <div class="wrapper container nav-header">
        <br>

        <nav class="navbar">
