I am very new to Polymer and I was trying use a paper-menu-button inside a paper-toolbar, to reproduce what was shown by Kevin Schaaf on Polymer Summit 2015, but it turns out that the element is not shown. Bellow is my code:
<link rel="import" href="../bower_components/iron-icons/iron-icons.html">
<link rel="import" href="../bower_components/polymer/polymer.html">
<link rel="import" href="../bower_components/paper-toolbar/paper-toolbar.html">
<link rel="import" href="../bower_components/paper-input/paper-input.html">
<link rel="import" href="../bower_components/paper-icon-button/paper-icon-button.html">
<link rel="import" href="../bower_components/paper-menu-button/paper-menu-button.html">
<dom-module id="input-header">
<template>
<paper-toolbar>
<paper-icon-button icon="mail"></paper-icon-button>
<div>{{title}}</div>
<paper-menu-button>
<paper-icon-button icon="more-vert"></paper-icon-button>
<paper-input label="Thread name:" value="{{title}}"></paper-input>
</paper-menu-button>
</paper-toolbar>
</template>
<script>
Polymer({
is: 'input-header',
properties: {
label: {
type: String,
notify: true
}
}
});
</script>
</dom-module>
What Am I doing wrong? Thanks in advance.
The classes are important. Also you don't have a paper-menu with the dropdown-content class defined. I'm not sure about having paper-input???
<paper-menu-button>
<paper-icon-button icon="menu" class="dropdown-trigger"></paper-icon-button>
<paper-menu class="dropdown-content">
<paper-item>Share</paper-item>
<paper-item>Settings</paper-item>
<paper-item>Help</paper-item>
</paper-menu>
</paper-menu-button>
I have no idea what you are trying. Using paper-input inside paper-menu-button which should show some items doesn't make point for me, but anyway, if you want to see paper-icon-button inside paper-menu-button you have to add dropdown-trigger class.
Code should be:
<paper-toolbar>
<paper-icon-button icon="mail"></paper-icon-button>
<div>{{title}}</div>
<paper-menu-button>
<paper-icon-button icon="more-vert" class="dropdown-trigger"></paper-icon-button>
<paper-input label="Thread name:" value="{{title}}"></paper-input>
</paper-menu-button>
</paper-toolbar>
paper-menu-button should have some dropdown content so that's why i don't get it.
Maybe use some wrap div around paper-icon-button and paper-input and set dropdown-trigger class to it

I have a very basic attempt at implementing paper-menu. However the rendered HTML is not right and breaks the interaction. When clicking a menu item, the entire list disappears. I've identified it's because the paper-item elements are not rendered inside a very key div inside the paper-menu element.
My component.html looks like this:
<div>
<paper-menu selected="0">
<paper-item>Location 1</paper-item>
<paper-item>Location 2</paper-item>
</paper-menu>
</div>
However, what gets rendered is like this:
<div>
<paper-menu role="menu" tabindex="0" selected="0" class="x-scope paper-menu-0">
<div class="selectable-content style-scope paper-menu">
</div>
<paper-item role="option" tabindex="0" aria-disabled="false" class="x-scope paper-item-0">Location 1</paper-item>
<paper-item role="option" tabindex="0" aria-disabled="false" class="x-scope paper-item-0">Location 2</paper-item>
</paper-menu>
</div>
If I manipulate the rendered HTML in the browser so the close div tag properly wraps the paper-item elements, the interaction works.
What am I doing wrong?
In my index.html I have:
<script src="lib/webcomponentsjs/webcomponents-lite.js"></script>
<link rel="import" href="lib/paper-button/paper-button.html" />
<link rel="import" href="lib/paper-input/paper-input.html" />
<link rel="import" href="lib/paper-item/paper-item.html" />
<link rel="import" href="lib/paper-menu/paper-menu.html" />
<link rel="import" href="lib/paper-listbox/paper-listbox.html" />
<link rel="import" href="lib/paper-toggle-button/paper-toggle-button.html" />
<link rel="import" href="lib/paper-progress/paper-progress.html" />
<link rel="import" href="lib/paper-dropdown-menu/paper-dropdown-menu.html" />
And in my bower.json I am referencing the following versions
{
"name": "permit-manager-app",
"private": true,
"dependencies": {
"polymer": "^1.4.0",
"webcomponentsjs": "^0.7.22",
"paper-button": "^1.0.11",
"paper-input": "^1.1.10",
"paper-progress": "^1.0.9",
"paper-dropdown-menu": "1.2.1",
"paper-menu": "1.2.2",
"paper-item": "1.2.1",
"paper-listbox": "1.1.2",
"paper-toggle-button": "^1.1.2"
}
}
And this is Angular2 beta 17
I've come across a similar issue within the same project with the paper-dropdown-menu where a critical section is rendered out of place and the control does not function.
details are here:
Polymer paper-dropdown-menu not rendered correctly in browser
I'm learning Polymer and I encountered a little problem while doing the menu. Apparently, when I add the dropdown menu it displays opened always, it doesn't close and open at will. Also, I checked the code at the github repo from Polymer and its demos and can't find out what am I doing wrong.
<paper-toolbar>
<paper-menu-button>
<paper-icon-button icon="menu" class="dropdown-trigger"></paper-icon-button>
<paper-menu class="dropdown-content">
<paper-item>Share</paper-item>
<paper-item>Settings</paper-item>
<paper-item>Help</paper-item>
</paper-menu>
<paper-menu-button>
</paper-menu-button>
<div class="title">Title</div>
<paper-icon-button icon="refresh"></paper-icon-button>
</paper-toolbar>
You are having an extra <paper-menu-button> before
</paper-menu-button>
<div class="title">Title</div>
This is how your code should looks

I don't know if you have imported all the required imports, but here is a Plunkr , you can see it in action
Please provide a working JSBin that makes this <paper-toolbar> "look pretty" as follows:
Vertically center the <paper-input> and <paper-dropdown-menu> elements to the middle of the <paper-toolbar>.
Vertically align the <paper-input> and <paper-dropdown-menu> horizontal input field lines with each other.
Horizontally space the <paper-input> and <paper-dropdown-menu> elements between each other by at least 20px.

Hi I am trying to vulcanize my app but using webcomponents-lite.js doesnt seem to polyfill correctly and reading up I found a suggestion that says to use webcomponents.js, problem there is when I use that i get these errors:
Unable to get property 'mousedown' of undefined or null reference
Unable to get property 'click' of undefined or null reference
and thats if I vulcanize or not. Must say I am having more issues using Polymer than I think I should. Works no problem with Chrome but other browsers fight me at every turn.

the app loads slowly which makes sense as I am importing alot so the vulcanize was suggested to sort that out. And I get a random hierarchy message on IE. if I reload the page a few time it foes away. Again vulcanize was suggested to fix that as well
The issue is caused by the ShadowDOM polyfill.
If webcomponents-lite.js, which doesn't have ShadowDOM, is used instead of webcomponents.js then all will work correctly.
Since 0.8-preview polymer only depends on webcomponents-lite.js, so you can use this instead of webcomponents.js without any problem: ShadowDom polyfill will definitely be unnecessary since polymer 0.8-preview
Personally, I have not needed to use the Shadow DOM so far...
Example of Shadow DOM:
<dom-module id="my-webcomponent">
<style>
...
</style>
<!-- //////////// Content of <template> will be appended to the <my-webcomponent> tag (works perfectly with webcomponents-lite.js) -->
<template>
<h1>Shadow Root!</h1>
</template>
<!-- //////////// This is Shadow DOM (doesn't work with webcomponents-lite.js) -->
<div id="outsideTemplate">
<h1>Shadow DOM!</h1>
</div>
<script>
Polymer({
is: "my-webcomponent",
...
...
...
});
</script>
</dom-module>

If you still want to use webcomponents.js and have problems with JQuery, perhaps (I have not tried it) there are one "solution":
You could wrap all your JQuery stuff inside this IIFE:
(function(document) {
// JQuery code here
})(wrap(document));
NOTE:
Firefox team are (still) working on it: https://hacks.mozilla.org/2014/12/mozilla-and-web-components/
Using Polymer 1.0, I have created a paper-drawer-panel layout. In the drawer I have a menu using paper-menu with paper-items which are bound to the iron-pages. I took this example from Content Switcheroo with Core-Pages -- Polycasts #09 and converted it to use the Polymer 1.0 elements. In the code below you can see my commented section in which the paper-items are hard-coded. This works fine.
My next step was to try and build my menu dynamically by using the <template is="dom-repeat"> element to iterate over an arbitrary array of menu items. The menu is rendered correctly (I can see all the menu items that are bound to the array), but I cannot click on the items and no iron-pages are displayed. It seems that the data-category attribute which is used for attr-for-selected is not working inside <template is="dom-repeat">.
In what ways can I get this to work?
Edit: Removing the attr-for-selected attributes and switching the iron-pages using the index work, but relying on the index of the array is not an option in my situation.

Try <paper-item data-category$="{{item.itemNum}}" label$="{{item.itemNum}}">, from the docs, that will call paper-item.setAttribute('data-category', itemNum) instead of paper-item.data-category = itemNum.
