Dave,

The popup window and reszing working now. I Modified the Circle Icon code in HTML Template and added client script. Changes are here.

<!--// Circle Icon popUp-->
<a ng-click="c.openPopUp()" class="circle_icon {{::options.class_name}} text-{{::options.color}}" >
<span class="image-container" ng-if="options.u_image">
<img class="media-object" src="{{::options.u_image}}" width="55" height="55" alt="${{{options.title}}}" style="cursor:pointer;">
</span>
<h2 style="cursor:pointer;">{{::options.title}}</h2>
<span class="text-muted" style="cursor:pointer;">{{::options.short_description}}</span>
</a>

Added this in client script in Client controller:

// Client script
function() {
var c = this;
c.openPopUp = function() {
var url = "my url";
var popup = window.open (url, "popup", "width=900, height=600");
}
}
