# Vertical Spacing between headings in nested multicol List

Hi I have the following MWE and would like to know if using \\ is BP or if there is a clear/better way to achieve the spacing between each headings. General opinions on the look of this are welcomed as well.

MWE:

\documentclass[12pt]{scrreprt}
\usepackage[a4paper, includehead, left=3.5cm, right=1.7cm, top=2.5cm, bottom=2.0cm]{geometry}

\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}

\usepackage{multicol}
\usepackage[onehalfspacing]{setspace}
\usepackage{enumitem}

\begin{document}
\begin{multicols}{2}
\setlist[itemize]{wide =0pt, leftmargin=*, nosep,before=\KOMAoptions{parskip=false}}
\begin{enumerate}[topsep=0pt,itemsep=-1ex,partopsep=1ex,parsep=1ex,leftmargin=*]
\begin{itemize}
\item Item 1
\item Item 2
\\
\end{itemize}
\begin{itemize}
\item Item 1
\item Item 1
\item Item 1
\\
\end{itemize}
\begin{itemize}
\item Item 1
\item Item 1
\item Item 1
\item Item 1
\vfill\null
\columnbreak
\end{itemize}
\begin{itemize}
\item Item 1
\item Item 1
\item Item 1
\item Item 1
\\
\end{itemize}
\begin{itemize}
\item Item 1
\item Item 1
\item Item 1
\item Item 1
\\
\end{itemize}
\end{enumerate}
\end{multicols}

\end{document}

• Forgive my ignorance, but what does BP mean? British Petroleum? Jul 21 '17 at 11:16
• In my understanding it is best practice, but if it is not commonly used, it kind of defeats the purpose. Jul 21 '17 at 12:02
• I'm not very fluent at Acronym… More seriously, are you sure you don't want horizontal enumerate (I mean the layout would be: 1. Heading 2. Heading (nextline)3. Heading 4. Heading, &c. Jul 21 '17 at 12:28
• You are talking about tasks i guess? What would that look like for my example? Jul 21 '17 at 12:44

Changing parsep to 3.5ex seems to achieve what you want, without the use of added blank lines \\.
