everyone!
I wanted to use paper-header-panel with mode waterfall and custom element 'iron-swipeable-pages'. My code looks somehow like this: (it is not the exact copy, just the structure)
<paper-drawer-panel id="drawer" force-narrow>
<div drawer>
<!-- Drawer panel -->
</div>
<div main>
<paper-header-panel id="paperHeaderPanel" mode="waterfall">
<paper-toolbar id="appbar">
<!-- Toolbar content -->
</paper-toolbar>
<iron-swipeable-pages
padding="16"
id="ironSwipeablePages"
edge-swipe-sensitivity="30"
selected="{{selected}}">
<div id="overview">
1
</div>
<div id="timetable">
2
</div>
<div id="teachers">
3
</div>
<div id="calendar">
4
</div>
</iron-swipeable-pages>
</paper-header-panel>
</div>
</paper-drawer-panel>
The <div> elements inside <iron-swipeable-pages> are scrollable but when I scroll them the waterfall effect on paper-header-panel isn't working.
I tried this:
this.$.paperHeaderPanel.scroller = this.$.overview;
In ready script of element because I saw that property isn't marked as read-only in element reference. However, it does not work. Do you have any ideas how to make waterfall effect work?

Is it possible to include a round thumbnail in the paper-card element following the material design card specification on https://material.io/guidelines/components/cards.html#cards-actions ?

Is this possible with the paper-card Polymer 2 element?
You can achieve that by using paper-icon-item inside paper-card.
<paper-card heading="Emmental">
<div class="card-content">
<!-- Paper icon item starts here -->
<paper-icon-item>
<div class="avatar blue" slot="item-icon"></div>
<paper-item-body two-line>
<div>Alphonso Engelking</div>
<div secondary>Change photo</div>
</paper-item-body>
</paper-icon-item>
<!-- Paper icon item ends -->
</div>
<div class="card-actions">
<paper-button>Share</paper-button>
<paper-button>Explore!</paper-button>
</div>
</paper-card>
Hope this helps :)
I am building a full-screen app with Polymer. Currently, I've defined my layout like this:
<body unresolved class="fullbleed">
<template is="dom-bind" id="app">
<paper-scroll-header-panel fixed>
<paper-toolbar>
<div class="spacer title" style="margin-left:0px;">My App</div>
<paper-icon-button icon="search"></paper-icon-button>
<paper-icon-button icon="more-vert"></paper-icon-button>
</paper-toolbar>
<paper-drawer-panel id="paperDrawerPanel">
<div drawer>
<my-nav flex></my-nav>
</div>
<div main class="content">
<my-view></my-view>
</div>
</paper-drawer-panel>
</paper-scroll-header-panel>
</template>
</body>
The view in <div main class="content"> looks like this:
my-view.html
<dom-module id="project-view">
<template>
<neon-animated-pages class="flex" selected="[[selectedPageIndex]]" entry-animation="fade-in-animation" exit-animation="fade-out-animation">
<!-- Page 1 -->
<div>
<paper-header-panel mode="seamed">
<div class="paper-header">
<paper-toolbar class="view-toolbar">
<paper-icon-button icon="menu"></paper-icon-button>
<span class="flex"></span>
<paper-icon-button icon="menu"></paper-icon-button>
</paper-toolbar>
</div>
<div class="content">
<paper-material elevation="2">
<h1>Welcome</h1>
<p>
This will be a BIG text block that require scrolling. The toolbar should always be visible. The "paper" should scroll under the toolbar like a Google Doc
</p>
</paper-material>
</div>
</paper-header-panel>
</div>
<!-- Page 2 -->
<div>
<paper-material elevation="2">
<p>Another page</p>
</paper-material>
</div>
</neon-animated-pages>
<script>
Polymer({
is: "my-view",
ready: function() {
this.selectedPageIndex = 0;
}
});
</script>
</template>
</dom-module>
When I run this page, the content under the toolbar will not scroll. It stays fixed in position. I do not understand why. How do I create some paper under a toolbar so that it scrolls beneath the toolbar like Google Docs?
Update:
Main layout changed to:
<paper-header-panel class="flex" style="background-color:lightcoral;">
<paper-toolbar>
<div class="spacer title" style="margin-left:0px;">My App</div>
<paper-icon-button icon="search"></paper-icon-button>
<paper-icon-button icon="more-vert"></paper-icon-button>
</paper-toolbar>
<div class="flex content" style="background-color:lightsalmon;">
<div class="horizontal layout">
<div drawer>
<my-nav flex></my-nav>
</div>
<div main class="content">
<my-view></my-view>
</div>
</div>
</div>
</paper-header-panel>
The content scrolls. However, the content of the paper-drawer-panel does not fill the remaining area below the toolbar. I do not understand why. It's like the iron-flex-layout stuff isn't working. What am I doing wrong?
My guess is that it has something to do with the paper-drawer-panel being inside of the paper-scroll-header-panel element. On top of that likely being the culprit, you should consider that if you do have the paper-drawer-panel inside of the paper-scroll-header-panel, it will scroll with your content.
I would try either removing or moving the paper-drawer-panel to start with, and then adding it back in once you have the scrolling working.
I'm not sure if this is already implemented, but this blog post might help you as it explicitly mentions the paper-toolbar together with flex layout :
https://blog.polymer-project.org/announcements/2015/12/01/deprecating-deep/
So you could try using mixins instead of the flex-class.
Try to use paper-dialog-scrollable. All you have to do is set width and height of the scroll area. Works with static and dynamic content.
I'm trying to use paper elements, and I played a bit with the different panels. I tried modifying the example from the documentation:
<paper-drawer-panel>
<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>
I want to have the drawer inside the header panel, so that the header take the whole width of the page.
Here is my attempt: (plunker)
<body class="fullbleed layout vertical">
<paper-header-panel>
<paper-toolbar>
<paper-icon-button icon="menu" paper-drawer-toggle></paper-icon-button>
<paper-icon-button icon="menu" (click)="document.querySelector('#panel').togglePanel()"></paper-icon-button>
<div>My app</div>
</paper-toolbar>
<paper-drawer-panel id="panel">
<div drawer> drawer </div>
<div main> main </div>
</paper-drawer-panel>
</paper-header-panel>
</body>
Here, the drawer doesn't close. The buttons don't do anything. In my console, I can use $('#panel').togglePanel(), and I see it changing the selected attribute on the panel, but the drawer doesn't close. What's wrong with my code and how can I make the "menu" button close my drawer?
Edit: replaced $('#panel') by document.querySelector('#panel')
You were trying to use JQuery, here is the Javascript way of doing it:
replace:
(click)="$('#panel').togglePanel()"
with:
onClick="document.querySelector('#panel').togglePanel()"
As part of my page I have a list that I need to attach a scroll bar too. The entire page is within a paper-header-panel. If I give the paper-scroll-header-panel a height in pixels then it displays fine but otherwise, even if I set it to "width: 100%" it will not display. It seems it ought to be easier then I am trying to make it. are there any tips you can send along as to what I might be doing wrong?

Your paper-scroll-header-panel displays fine if you display it by itself. Maybe this is why it's not displaying in your sample:
The documentation for paper-scroll-header-panel says:
Important: The paper-scroll-header-panel will not display if its parent does not have a height.
https://elements.polymer-project.org/elements/paper-scroll-header-panel
I'm working with a icon button which is placed in a scroll header panel. Even though I explicitly added a rule for the width, it is still showing up as 100% width:
What is so strange is that if I move the button and place it into the content of the page, the size is right again. I just can't figure out what is messing up the width.
Relevant code:
<paper-drawer-panel transition>
<div drawer></div>
<paper-scroll-header-panel class="flex" condenses main>
<paper-toolbar class="tall">
<paper-icon-button icon="menu" title="menu" paper-drawer-toggle></paper-icon-button>
<div class="bottom title">Title</div>
</paper-toolbar>
<div class="content">
</div>
