我正在使用 Angular 4 开发一个网站。我决定在开发过程的早期使用 Bulma CSS 框架，因为我喜欢这个设计。Bulma 没有用于下拉菜单的内置组件，因此在尝试创建自己的菜单失败后，我添加了 NgBootstrap。

我的问题是，Bulma 的内置导航栏正在打开导航栏中的菜单并通过垂直滚动条显示它。如何设置导航栏或菜单的样式以在导航之外打开？

这是部署在heroku上供查看的网站。测试是 ngbootstrap，其余的都是通过悬停菜单从头开始构建的。 http://atozinsurance.herokuapp.com/

这是我的导航组件的 HTML 代码。

我检查了如果我进行两次更改，它可以工作。自己试试：

.nav-right.nav-menu {
    overflow-y: visible;
}
.nav-item[_ngcontent-c1], .nav-right[_ngcontent-c1] {
    overflow-x: visible !important;
}

希望能帮助到你！
