ion-header
Contents
Header is a parent component that holds the toolbar component. It's important to note that ion-header needs to be the one of the three root elements of a page
Fade Header
The collapse
property can be set to 'fade'
on a page's main ion-header
to have the background color of the toolbars fade in as users scroll. This provides the same fade effect that is found in many native iOS applications.
This functionality can be combined with Collapsible Large Titles as well. The collapse="condense"
value should be set on the ion-header
inside of your ion-content
. The collapse="fade"
value should be set on the ion-header
outside of your ion-content
.
Usage with Virtual Scroll
Fade and collapsible large titles require a scroll container to function. When using a virtual scrolling solution, you will need to disable scrolling on the ion-content
and indicate which element container is responsible for the scroll container with the .ion-content-scroll-host
class target.
<ion-header collapse="fade">
<ion-toolbar>
<ion-title>Header</ion-title>
</ion-toolbar>
</ion-header>
<ion-content fullscreen="true" scroll-y="false">
<ion-header collapse="condense">
<ion-toolbar>
<ion-title size="large">Header</ion-title>
</ion-toolbar>
</ion-header>
<virtual-scroll-element class="ion-content-scroll-host">
<!-- Your virtual scroll content -->
</virtual-scroll-element>
</ion-content>
