Question

Ionic4 项目中我们可以使用 Ionic4 侧边栏组件 ion-menu-toggle 对项目进行布局。

ion-menu-toggle 官方文档地址：https://ionicframework.com/docs/api/menu-toggle

The MenuToggle component can be used to toggle a menu open or closed.

By default, it's only visible when the selected menu is active. A menu is active when it can be opened/closed. If the menu is disabled or it's being presented as a split-pane, the menu is marked as non-active and ion-menu-toggle hides itself.

In case it's desired to keep ion-menu-toggle always visible, the autoHide property can be set to false .
