I created one document type collection in compositions and added the parent composition in the home document type but I am unable to create an item of composition document. It is displaying only the parent document properties and not able to create items of child composition document.

I know there is nested content data type is available for element type but if I use the element type then I am getting a list of items by item1, item2, item3 which is very difficult to identify the type of content.
