Where do I place the child project in the TOC?
You can place the child project anywhere in the TOC of the master project (as a subbook or a top-level book). After inserting the child projects into the TOC, you can drag them to the selected location in the TOC. However, you cannot separate or divide the child project TOC in the master TOC. The TOC of the child project appears in its entirety where you place it.
