In this article is shown the way how to extend the Archive widget in order to show the Dynamic Items. The currently supported Items and setting up of the Build-in widget is described in that documentation article.

}
In order to set-up the widget to show the Dynamic items you need to:
1. Create a Class file and Paste the code above
(In the example: CustomArchiveWidget.cs file under “Controls” folder)
2. Build the solution
3. Register the widget using Sitefinity Thunder following that article
(Manual registration in toolboxes is described here)
4. Get the ContentType of your dynamic Item. To do so
- Go to Administration > Module Builder > <your module>
- Open “Code reference for <your module>”
- Select your ContentType and select one of the Code Snippet (For example: Create “<your content tyle>”
- Copy the content type
5. Create e new Page or Edit an existing one
6. Drag the Archive widget on that page
7. Add the widget for your content type on the page (In our case ContentTwo)
8. Click the Edit button in the upper-right corner of the Custom Archive widget.
9. In ContentType input field enter the content type get in step 1
(In our case “Telerik.Sitefinity.DynamicTypes.Model.TestModule1.Contenttwo”)
10. Set-up the other fields as per your need (documentation article)
11. Click Save
12. Publish the Page
I hope the above article was halpful.
