General ⇒ Split nomenclature over two lines, with content alligned on same lines under "nomenclature"

[LaTeX_monty]

Hi, I would like to split the nomenclature over two lines. I found a "code" for this at https://copyprogramming.com/howto/if-tw ... umns-latex
which states the following:

Code: Select all

\documentclass[]{article}
\usepackage[utf8]{inputenc}
\usepackage{amssymb}
\usepackage{verbatim}%to make comments
\usepackage{multicol}%for multiple columns
\usepackage{etoolbox}
%Nomenclature Package
%----------------------------------------------
\usepackage{nomencl}
\makenomenclature
\setlength{\nomitemsep}{8pt}
\newcommand{\nomunit}[1]{%
  \renewcommand{\nomentryend}{\hspace*{\fill}#1}%
}
\renewcommand\nomgroup[1]{% 
  \item[\bfseries
  \ifstrequal{#1}{A}{Stuff}{%
  \ifstrequal{#1}{B}{Other Stuff}{%
  \ifstrequal{#1}{C}{More Stuff}{}}}%
]}
\patchcmd{\thenomenclature}
 {\section*{\nomname}}
 {\begin{multicols}{2}[\section*{\nomname}]}
 {}{}
\appto\endthenomenclature{\end{multicols}}
\setlength{\columnsep}{2pc}
%----------------------------------------------
\title{Nomenclatures Example}
\author{}
\date{\today}
\begin{document}
\maketitle
\newpage
\printnomenclature
\nomenclature[A]{$m$}{Mass \nomunit{[kg]}}
\nomenclature[A]{$V$}{Velocity \nomunit{[m/s]}}
\nomenclature[A]{$t$}{Time \nomunit{[s]}}
\nomenclature[B, 03]{${R}$}{Real Numbers}
\nomenclature[B, 02]{${C}$}{Complex Numbers}
\nomenclature[B, 01]{${H}$}{Quaternions}
\nomenclature[C]{$V$}{Constant Volume}
\nomenclature[A]{$\rho$}{Friction Index}
\end{document}

However, it does not compile mye desired outcome, as it states that something is wrong in line 23 and 24 with the "{" and "}" marks. I can not figure what is wrong. At the website you can see the desired outcome under "Solution" to question 2.
Any suggestions to this?

I found a good solution for the problem here:
