I would like to modify the \partpage such that it shows a table of contents of that part. Preferably also one or two levels deeper than the toc in the beginning of the document.
In styling the \part page Alan Munn shows how to edit the page,
\documentclass{report}
\usepackage{titlesec,minitoc}
\titleclass{\part}{top}
\titleformat{\part}
{\centering\normalfont\Huge\bfseries}
{}
{0pt}
{}
\begin{document}
\tabkeofcontents
\part{This is the Part}
\minitoc %\parttoc,\doparttoc
\chapter{This is its first chapter}
\chapter{This is its second chapter}
\end{document}
but how do I add the 'minitoc'? In the above snippet neither \minitoc nor \parttocor \doparttoc have any effect. \minitoc only works for chapters - not parts. Is there any other option or a smart modification I did not find?
