# Using label* to append enumitem labels but resetting the font

I'm trying to create a legal-like list that has numbering like 1., 1.1., etc., except where the top level numbers are bolded, and the rest aren't.

Currently I have:

\documentclass{article}
\usepackage{enumitem}

\newlist{questions}{enumerate}{2}
\setlist[questions,1]{label=\textbf{\arabic*.}}
\setlist[questions,2]{label*=\arabic*.}

\begin{document}

\begin{questions}

\item Top level (number should be bolded)

\begin{questions}

\item Second level (whole number should be in normal font)

\end{questions}

\end{questions}

\end{document}


which gives me:

So the second level has correctly appended a normal-font number onto the label from its parent, but it also kept the bolding in the parent's number (which I don't want).

I tried adding the font=\normalfont option to the second questions level, but that didn't have any effect.

Is there a good way to remove formatting from the parent label before appending to it?

Simply use the font key for the first level:

\documentclass{article}
\usepackage{enumitem}

\newlist{questions}{enumerate}{2}
\setlist[questions, 1]{label=\arabic*., font=\bfseries}
\setlist[questions, 2]{label*=\arabic*.}

\begin{document}

\begin{questions}

\item Top level (number should be bolded)

\begin{questions}

\item Second level (whole number is in normal font)

\end{questions}

\end{questions}

\end{document}


I would declare a formatting command and then change that formatting command before any deeper levels are reached.

\documentclass{article}

\usepackage{enumitem}

\DeclareRobustCommand{\questionformat}{\textbf}

\newlist{questions}{enumerate}{2}
\setlist[questions,1]{label=\questionformat{\arabic*.}}
\setlist[questions,2]{label*=\arabic*.,before={\DeclareRobustCommand{\questionformat}{}}}

\begin{document}

\begin{questions}
\item Top level (number should be bolded)
\begin{questions}
\item Second level (whole number should be in normal font)
\item Second level (whole number should be in normal font)
\end{questions}

\item Top level (number should be bolded)
\begin{questions}
\item Second level (whole number should be in normal font)
\item Second level (whole number should be in normal font)
\end{questions}
\end{questions}

\end{document}


Since the hierarchy stores expanded versions of higher levels, \DeclareRobustCommand avoids expansions and therefore preserves the formatting command (making it changeable). However, don't use a \reference to one of the nested elements...

• Ah, that's really cool. Kind of overkill for just the bold/non-bold application, but I'll definitely keep it in mind for more complex label formatting. Thanks! – Niayesh Isky Mar 16 '18 at 21:24
