ion-split-pane官方文档地址:https://ionicframework.com/docs/api/split-pane

SplitPane is a component that makes it possible to create multi-view layout. Similar to iPad apps, SplitPane allows UI elements, like Menus, to be displayed as the viewport increases.

If the devices screen size is below a certain size, the SplitPane will collapse and the menu will become hidden again. This is especially useful when creating an app that will be served over a browser or deployed through the app store to phones and tablets.

Setting breakpoints

By default, SplitPane will expand when the screen is larger than 992px. If you want to customize this, use the when input. The when input can accept any valid media query, as it uses matchMedia() underneath.

SplitPane also provides some predefined media queries that can be used.

</ion-split-pane>

Size	Value	Description
xs	(min-width: 0px)	Show the split-pane when the min-width is 0px (meaning, always)
sm	(min-width: 576px)	Show the split-pane when the min-width is 576px
md	(min-width: 768px)	Show the split-pane when the min-width is 768px
lg	(min-width: 992px)	Show the split-pane when the min-width is 992px (default break point)
xl	(min-width: 1200px)	Show the split-pane when the min-width is 1200px

You can also pass in boolean values that will trigger SplitPane when the value or expression evaluates to true.
