ion-split-pane

A split pane is useful when creating multi-view layouts. It allows UI elements, like menus, to be displayed as the viewport width increases.

If the device's screen width is below a certain size, the split pane will collapse and the menu will be hidden. This is ideal for creating an app that will be served in a browser and deployed through the app store to phones and tablets.

Setting Breakpoints

By default, the split pane will expand when the screen is larger than 992px. To customize this, pass a breakpoint in the when property. The when property can accept a boolean value, any valid media query, or one of Ionic's predefined sizes.

<!-- can be "xs", "sm", "md", "lg", or "xl" -->
<ion-split-pane when="md"></ion-split-pane>

<!-- can be any valid media query https://developer.mozilla.org/en-US/docs/Web/CSS/Media_Queries/Using_media_queries -->
<ion-split-pane when="(min-width: 40px)"></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
