@expose(template="flexable:flexable_example.templates.example")
def example(self):
return dict(message="This is flexable message.",
contents=""" This is main contents from controller.
flexable is merge values to given html template with class attribute.
""")

flexable_example/templates/example.html::

&lt;?xml version="1.0"?>
&lt;html xmlns="http://www.w3.org/1999/xhtml">

&lt;span class="message">&lt;/span>
&lt;p class="contents">&lt;/p>
&lt;span class="widget"/>
