Introduction

This guide teaches you how to use Paper and Iron elements to create a
responsive layout.

Installation

Below is a list of commands for installing all of the elements mentioned
in this document. You probably
do not need to install all of these elements. Read the guide and decide
how you want to implement your layout, and then install only the elements
that you need.

bower install --save PolymerElements/paper-header-panel
bower install --save PolymerElements/paper-toolbar
bower install --save PolymerElements/paper-drawer-panel
bower install --save PolymerElements/paper-icon-button
bower install --save PolymerElements/paper-tabs
bower install --save PolymerElements/paper-tab
bower install --save PolymerElements/iron-icons
bower install --save PolymerElements/iron-flex-layout

We'll assume that you can import these elements from /bower_components/.

Creating a header

This section shows you how to:

Create a standard layout with paper-header-panel and paper-toolbar,
which is probably the most common and easiest layout.
Use a custom element for a header.
Add icons to a header.
Set the height of a header.
Add tabs to a header.
Modify the disply and behavior of a header.

Creating a header with `paper-toolbar`

The code below uses a paper-header-panel as the container of the
page and a paper-toolbar as a header. When a paper-toolbar is a
child of paper-header-panel, the panel automatically displays
the toolbar as the header. All other
children are placed in the content area.

...
<head>
...
  <link rel="import" 
        href="/bower_components/paper-header-panel/paper-header-panel.html">
  <link rel="import" 
        href="/bower_components/paper-toolbar/paper-toolbar.html">
  <link rel="import" 
        href="/bower_components/iron-flex-layout/iron-flex-layout.html">
...
<body class="fullbleed vertical layout">
  <!-- paper-header-panel must have an explicit height -->
  <paper-header-panel class="flex">
    <paper-toolbar>
      <div>Header</div>
    </paper-toolbar>
    <div>Content</div>
  </paper-header-panel>
</body>
...

<a href="assets/header-and-toolbar.html" target="_blank">
<paper-button noink>Demonstration</paper-button>
</a>

paper-header-panel must have an explicit height. See the list item
on flex below for an explanation of why the code above works.

fullbleed, vertical, layout, and flex are helper classes from
iron-flex-layout.html. We use them in our examples as an easy way
to create a responsive design with Flexbox,
but the paper elements do not depend
on them. Below is a description of each class used in the example above:

fullbleed instructs body to occupy the entire viewport.
vertical and layout instruct body to stack elements
vertically (use vertical horizontal to stack horizontally). layout
must be accompanied by vertical or horizontal. It is meaningless
on its own.
flex instructs paper-panel-header to stretch to the entire
size of its parent, in this case body (which is set to fill the entire
viewport, hence achieving a responsive design).

See Flexbox layout with iron-flex-layout for more
on iron-flex-layout.

Using other elements for the header

You can use another element as a header by adding the
paper-header class to the element.

<head>
  <link rel="import" 
        href="/bower_components/paper-header-panel/paper-header-panel.html">
  <link rel="import" 
        href="/bower_components/iron-flex-layout/iron-flex-layout.html">
...
<body class="fullbleed vertical layout">
  <paper-header-panel class="flex">
    <div class="paper-header">
      Header
    </div>
    <div>Content</div>
  </paper-header-panel>
</body>

<a href="assets/custom-header.html" target="_blank">
<paper-button noink>Demonstration</paper-button>
</a>

Adding icons

Use paper-icon-button and iron-icons to add icons to your header:

...
<head>
...
  <link rel="import" 
        href="/bower_components/paper-header-panel/paper-header-panel.html">
  <link rel="import" 
        href="/bower_components/paper-toolbar/paper-toolbar.html">
  <link rel="import" 
        href="/bower_components/paper-icon-button/paper-icon-button.html">
  <link rel="import" 
        href="/bower_components/iron-icons/iron-icons.html">
  <link rel="import" 
        href="/bower_components/iron-flex-layout/iron-flex-layout.html">
...
<body class="fullbleed vertical layout">
  <paper-header-panel class="flex">
    <paper-toolbar>
      <div>Header</div>
      <span class="flex"></span>
      <paper-icon-button icon="search"></paper-button-icon>
    </paper-toolbar>
    <div>Content</div>
  </paper-header-panel>
</body>

<a href="assets/icons.html" target="_blank">
<paper-button noink>Demonstration</paper-button>
</a>

paper-icon-button displays the icon and handles the icon's behavior.
iron-icons is a collection of SVG icons which you can use for free
in your project.

How does the search icon display on the right side? The trick
is the span between the div and the paper-icon-button.
The div containing the text Header only takes up as
much space as is needed to display
the text content. Same with the paper-icon-button; it only takes up
as much space as is needed to display the icon. The flex
class forces the span to fill the entire space between the div and
the paper-icon-button.

Setting the height

Use the medium-tall (2x regular height) and tall (3x regular height) style
classes to change the height of your header.

...
<head>
...
  <link rel="import" 
        href="/bower_components/paper-header-panel/paper-header-panel.html">
  <link rel="import" 
        href="/bower_components/paper-toolbar/paper-toolbar.html">
  <link rel="import" 
        href="/bower_components/iron-flex-layout/iron-flex-layout.html">
...
<body class="fullbleed vertical layout">
  <paper-header-panel class="flex">
    <paper-toolbar class="tall">
      <div>Header</div>
    </paper-toolbar>
    <div>Content</div>
  </paper-header-panel>
</body>
...

<a href="assets/tall-header.html" target="_blank">
<paper-button noink>Demonstration</paper-button>
</a>

Adding tabs

Use paper-tabs to add tabs to your header:

...
<head>
...
  <link rel="import" 
        href="/bower_components/paper-header-panel/paper-header-panel.html">
  <link rel="import" 
        href="/bower_components/paper-toolbar/paper-toolbar.html">
  <link rel="import" 
        href="/bower_components/paper-icon-button/paper-icon-button.html">
  <link rel="import"
        href="/bower_components/paper-tabs/paper-tabs.html">
  <link rel="import" 
        href="/bower_components/iron-icons/iron-icons.html">
  <link rel="import" 
        href="/bower_components/iron-flex-layout/iron-flex-layout.html">
...
<body class="fullbleed vertical layout">
  <paper-header-panel class="flex">
    <paper-toolbar class="medium-tall">
      <paper-icon-button id="navicon"
                         icon="menu"></paper-icon-button>
      <!-- flex class forces span to fill space between icons -->
      <span class="flex">Title</span>
      <!-- icon displays at right because of span class above -->
      <paper-icon-button id="morebutton"
                         icon="more-vert"></paper-icon-button>
      <paper-tabs class="bottom fit" selected="0">
        <paper-tab>ONE</paper-tab>
        <paper-tab>TWO</paper-tab>
      </paper-tabs>
    </paper-toolbar>
    <div>Content</div>
  </paper-header-panel>
</body>
...

<a href="assets/tabs.html" target="_blank">
<paper-button noink>Demonstration</paper-button>
</a>

Modifying header display and behavior

Use the mode attribute of paper-header-panel to control how the
header displays and responds to scrolling. The list below describes
the different valid values for mode. See the link below for a
demonstration of all modes.

standard: The header appears at a higher level than the content area,
with a drop shadow. Content scrolls under the header.
seamed: The header appears at the same level as the content area,
with a seam between the two (no drop shadow). Content scrolls under the header.
waterfall: The header initially presents as seamed. When content scrolls
under the header, the header raises up and casts a drop shadow (as in
standard mode).
waterfall-tall: Like waterfall, except that the toolbar starts off
tall (3x standard height) and condenses to a standard-height
toolbar as the user scrolls. In this mode, paper-header-panel controls
the height of the toolbar, so you should not set it yourself (via
medium-tall or tall).
scroll: The header is seamed with the content and scrolls with the content.
cover: The content scrolls over the header. This mode is designed to
be used with narrow content (for example cards).

<paper-button noink>Demonstration</paper-button>
</a>

Creating a responsive navigation drawer

Use paper-drawer-panel to create a left-side or right-side
navigation menu.

<head>
  <link rel="import"
        href="/bower_components/paper-drawer-panel/paper-drawer-panel.html">
  <link rel="import" 
        href="/bower_components/paper-header-panel/paper-header-panel.html">
  <link rel="import" 
        href="/bower_components/paper-toolbar/paper-toolbar.html">
  <link rel="import" 
        href="/bower_components/paper-icon-button/paper-icon-button.html">
  <link rel="import" 
        href="/bower_components/iron-icons/iron-icons.html">
  <link rel="import" 
        href="/bower_components/iron-flex-layout/iron-flex-layout.html">
...
<body class="fullbleed vertical layout">
  <paper-drawer-panel class="flex">
    <paper-header-panel drawer>
      <paper-toolbar>
        <div>Application</div>
      </paper-toolbar>
      <div> Drawer content... </div>
    </paper-header-panel>
    <paper-header-panel main>
      <paper-toolbar>
        <paper-icon-button icon="menu" paper-drawer-toggle></paper-icon-button>
        <div>Title</div>
      </paper-toolbar>
      <div> Main content... </div>
    </paper-header-panel>
  </paper-drawer-panel>
</body>

<a href="assets/drawer.html" target="_blank">
<paper-button noink>Demonstration</paper-button>
</a>

On narrow screens, the drawer is hidden by default. The user can
touch the button or swipe in order to display the drawer.
On wide screens, the drawer is always open and the button to open
the drawer is hidden.

Use the togglePanel method to hide or reveal the drawer
programmatically. Or, add the paper-drawer-toggle attribute to an
element. This attribute makes the element act as an open / close button and
removes the need to call togglePanel explicitly.

Any children with the drawer attribute set are placed in the navigation area.
Any children with the main attribute are placed in the main panel.
