Hi,
CMSListMenu menu web part/control has property called (Document types) ClassNames where you need to specify all of the document types which you would like to display within this web part/control. Secondly, please check if your documents in your content tree are configured to use “Show in navigation” option (
CMS Desk -> Content -> choose your page -> Properties -> Menu section).
Regarding your second question, you can use “URL redirection” option for this purpose which you can find in CMS Desk -> Content -> choose your page -> Properties -> Menu section.
Best regards,
Miroslav Remias
