I have polymer-element: example By default templates is not allowed to insert html. This sample is not working , because it's not allowed to insert html. Maybe exists the way to do that. ebidel One way to do this is through a *Changed watcher and setting the .innerHTML the node: <div id="div"></div> labelChanged: function() { this.$.div.innerHTML = this.label; } Then, for the <template repeat> case, wrap things up in a custom element that follows the similar pattern: https://stackoverflow.com/a/22208332 . <element inner-h-t-m-l="{{prop}}"></element> works for Polymer 2.

i have a custom footer-bar ( tabfooter ) that creates a set of buttons with inline SVG inside of it (for styling reasons its inline). I didnt want to put the complete code for all SVG into the attributes, so i just hand over some ids, which are used by the component to determine the paths on its own. <custom-tabfooter values="{" ids ":["A ","B ","C ","D "]}"></custom-tabfooter> The component then takes the object with the ID array inside and uses it for repeating the DOM elements that are needed: <dom-module id="custom-tabfooter"> <template> <template is="dom-repeat" items="{{values.ids}}">

I was able to get the select initialized correctly, but am running into issues after initialization. Specifically, when clicking the select to open it a type error is thrown in the select2 script when positioning the pop over.

I have a polymer element which triggers a custom event synchronously and I want to know whether the event was cancelled using event.preventDefault(). Using event.defaultPrevented I can know the intended action. This works on all browsers(Chrome, Canary, Firefox, Opera) but on IE 11 (not worried about older browsers) its not working. I know I can set some property on my event and check for that back where I am triggering and handle but want to know if there is something else which I missed. You can try out the code from http://jsbin.com/husamupi/1/edit I had the same problem and could solve it

For those cases where it's a custom element you're registering simply check that an element by this name hasn't already been registered. Obviously you can include more complex logic to vary the name, decorate the class, etc, however this simply checks to see if something is already registered using the
