在背景后面实现模态（模态弹出窗口未被带到前台）

Question

我的问题与：

相同

Materialize modal overlay the whole page (the modal popup was not brought to foreground)

我的模式出现在其背景之后。

HTML：

    <div class="navbar-fixed">
        <nav style="height: 65px">
            <div class="nav-wrapper">
                <a href="#" class="brand-logo center">

问题是我的导航div里面有模型结构。通过将我的模型结构放在div之外解决了我的问题。

请参阅图片了解层次结构。
