Advanced tools
A collection of elements, along with guidelines and templates that can be used to structure your app’s layout.
<app-header reveals>

<div main-title>My app</div>
<paper-icon-button icon="delete"></paper-icon-button>
<paper-icon-button icon="search"></paper-icon-button>

$ bower install PolymerElements/app-layout --save
<link rel="import" href="/bower_components/app-layout/app-layout.html">
app-box - A container element that can have scroll effects - visual effects based on scroll position.
app-drawer - A navigation drawer that can slide in from the left or right.
app-drawer-layout - A wrapper element that positions an app-drawer and other content.
app-grid - A helper class useful for creating responsive, fluid grid layouts using custom properties.
app-header - A container element for app-toolbars at the top of the screen that can have scroll effects - visual effects based on scroll position.
app-header-layout - A wrapper element that positions an app-header and other content.
app-toolbar - A horizontal toolbar containing items that can be used for label, navigation, search and actions.
The templates are a means to define, illustrate and share best practices in App Layout. Pick a template and customize it:
Sample code for various UI patterns:
Transform navigation: As more screen space is available, side navigation can transform into tabs. (Demo - Source)
Expand Card: Content cards may expand to take up more horizontal space. (Demo - Source)
Material Design Responsive Toolbar: Toolbar changes its height and padding to adapt mobile screen size. (Demo - Source)
Here are some web apps built with App Layout:
Distribution is now done with slots, so things have changed because of that,
1.x
<app-drawer-layout>
<app-drawer>...</app-drawer>
<div>content</div>
</app-drawer-layout>
2.0
<app-drawer-layout>
<app-drawer slot="drawer">...</app-drawer>
<div>content</div>
</app-drawer-layout>
1.x
<app-header-layout>
<app-header>...</app-header>
<div>content</div>
</app-header-layout>
2.0
<app-header-layout>
<app-header slot="header">...</app-header>
<div>content</div>
</app-header-layout>
1.x
<app-box effects="...">
<img background ...>
</app-box>
2.0
<app-box effects="...">
<img slot="background" ...>
</app-box>
In app-drawer-layout
, the drawer-toggle
element needs to be manually hidden
when app-drawer-layout
is not in narrow layout. To add this, add the following CSS rule where
app-drawer-layout
is used:
app-drawer-layout:not([narrow]) [drawer-toggle] {
display: none;
}
In app-drawer-layout
, if you specify a value for --app-drawer-width
, that value must be
accessible by both app-drawer
and app-drawer-layout
. This can be done by defining the value
on the :host
that contains (or html
if outside a shadow root):
:host {
--app-drawer-width: 300px;
}
app-scrollpos-control
has been removed from App Layout in favor of using multiple scrolling regions to preserve the scroll position. In terms of UX, document.rootScroller
is a new web platform API that will allow non-document scroll to hide the address bar on mobile.
