gap between first and second tier of a list

i use the itemize environment in my document to make listings. since i don't want the listings to take so much space, i always use \itemsep-10pt. However the gap between the first and second level of the listing doesn't get smaller by using the itemsep-command. how can i get rid of that gap? MWE:

\documentclass{scrreprt}
\begin{document}
\begin{itemize}
\itemsep-10pt
\item first item first lvl
\item second item first lvl
\begin{itemize}
\itemsep-10pt
(HUGE GAP HERE)
\item first item second lvl
\item second item second lvl
\end{itemize}
\end{itemize}
\end{document}


You can use enumitem for that without inserting manual actions

\documentclass{scrreprt}
\usepackage{enumitem,lipsum}
\begin{document}
\lipsum[1]
\begin{itemize}[noitemsep]
\item first item first lvl
\item second item first lvl
\begin{itemize}[nosep]
\item first item second lvl
\item second item second lvl
\end{itemize}
\end{itemize}
\lipsum[2]
\end{document}


See the manual for the difference between noitemsep and nosep options

• this solved the problem, thank you :) is there a way of setting "nosep" as standard setting for all "itemize" environments i use? – Max Aug 22 '15 at 16:05
• @Max In the preamble: \setlist[itemize,1]{noitemsep} \setlist[itemize,2]{nosep} to maintain percusse's settings or \setlist[itemize]{nosep} to have nosep. – Gonzalo Medina Aug 22 '15 at 16:09
• thanks to you, too! i don't really see the difference between nosep and noitemsep for the first itemize-lvl. i mean the manual says, nosep "removes all vertical spacing", but is there any other verticalspacing than just the itemsep in the first lvl? – Max Aug 22 '15 at 16:18
• @Max Distance to the surrounding paragraphs etc. – percusse Aug 22 '15 at 16:19
• ok, got all my answers now, thank you very much once again, guys. – Max Aug 22 '15 at 16:21
