<h3>Angular2 (beta1) Integration</h3>
<p>This example demonstrates integrating <code>vaadin-core-elements</code> with an Angular 2 app.
Notice that currently we can't declare light DOM content for a Web Component inside the component
template so in case of <code>vaadin-grid</code> we're required to configure the columns
trough the JS APIs instead of using the light dom <code>table</code> configuration.</p>
<p>Click a row to see an enlarged user image or change the value of the select in
<code>vaadin-grid</code> header to filter the results by gender.</p>
<p><strong>Note:</strong> IE isn't currently supported.</p>
<code-example>
<iframe src="angular-demo-embed.html" style="width: 100%; height: 600px; border: none; display: none;"></iframe>
<style>
iframe ~ [demo] {
display: none !important;
}
</style>
<div demo>
<vaadin-grid [columns]="columns" [items]="items" (selected-items-changed)="onSelect()">
</vaadin-grid>
<img *ngIf="selected" class="user-image" src="{{selected.user.picture.large}}">
<div style="display: none">
<select maxlength=5 (change)="onFilterChange()">
<option value=''></option>
<option value='male'>Men only</option>
<option value='female'>Women only</option>
</select>
</div>
</div>
<code>
/*

cell.element.innerHTML = '<img style="width: 30px" src="' + cell.data + '" />';
