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. ```bash 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. ```hmtl ... ... ...

... ``` Demonstration `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](http://www.smashingmagazine.com/2015/08/flexible-future-for-web-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](/guides/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. ```html ...

``` Demonstration `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. ```hmtl ... ... ...

... ``` Demonstration ### 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). Demonstration ## Creating a responsive navigation drawer Use `paper-drawer-panel` to create a left-side or right-side navigation menu. ```html ...

``` Demonstration 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.
