Hi All, I want to embed some custom HTML file in my content view. How can we achieve the same ?

Can anyone tell me how can I embed a custom HTML template in my Nuxeo content View. Basically, I want to load an HTML file using IFrame in Nuxeo. Is this possible ?

Edit

I have tried following things so far,

• Using the following link tried to understand how to create a custom layout and widget but the document just explains on how to create custom layout and widget and not how to confgiure them.
• Seeing some of the existing examples on Nuxeo forum I see that we can use extension points but again this is very high level and doesn't have thorough explaination on how you configure the templates defined in extension points. I tried creating my custom extension as below

<extension target="org.nuxeo.ecm.platform.forms.layout.WebLayoutManager"
    point="layouts">
    <layout name="req_custom_template">
      <aliases>
        <alias>Custom Template</alias>
      </aliases>
     <columns>
        <column name="last_contributor">
          <widget>req_custom_widget</widget>
        </column>
      </columns>
    </layout>
 </extension>

<extension target="org.nuxeo.ecm.platform.forms.layout.WebLayoutManager"
   point="widgets">
  <widget name="req_custom_widget" type="template">
    <labels>
      <label mode="any"></label>
    </labels>
    <translated>false</translated>
    <fields>
      <field>data</field>
    </fields>
      <properties widgetMode="any">
        <property name="template">/layouts/external_html.xhtml</property>
    </properties>
  </widget>
</extension>

and provided my custom template in NUXEO_HOME/templates/custom/layouts directory and published my content. And In studio, when I see the External Layouts dropdown for Document, I see as below,

However, I found that in the document creation layout there is an existing widget called templateand tried using my XHTML file there and use it. Upon publishing, I see my custom HTML content (which is great).

Still I would like to know what is the correct way of doing this.
