I would like to put a enumerate environment (customized with the enumitem package) inside of a shadowbox created from the Fancybox package. Here's my MWE:

\documentclass[letterpaper,10pt,american]{article}
\usepackage[left=1 in, right=1 in, top=1 in, bottom=1 in]{geometry}
\usepackage{amsmath,amsfonts,amssymb,amsthm,color,hyperref,enumitem}
\usepackage{setspace}
\usepackage{caption}
\usepackage{pgf,tikz}
\usetikzlibrary{automata,arrows,positioning,calc,decorations.pathreplacing}
\usepackage{fancybox}
\begin{document}
\shadowbox{
\begin{enumerate}[before=\itshape,font=\normalfont,label=\textbf{ABC.\arabic*}]
\item Item 1
\item Item 2
\item Item 3
\end{enumerate}}
\end{document}

However, the customization of my enumerate environment doesn't show up: only numbers 1., 2., 3. are displayed, rather than ABC.1, ABC.2, ABC.3. Am I doing something wrong? What's causing enumitem customization not to work inside fancybox?

EDIT: We've almost solved the issue! But there's still one small obstacle remaining to fix: When you have ten or more items in the list, then ABC.10, ABC.11, ABC.12, etc. will leak outside of the box.

Some improvements to @Harish Kumar's solution: enumitem has the tools to solve the leak problem for long labels: the key wide= and widest=.

There is also a problem in case of long items: the box leaks into the right margin. I propose 3 solutions for 3 different layouts: one with an indent on both sides, another where only the shadow leaks into the right margin, and no leak at all. Also, I simplified your code for the margins, since they're all equal, and used the showframe option to demonstrate what happens:

\documentclass[letterpaper,10pt]{article}
\usepackage[utf8]{inputenc}
\usepackage[margin=1 in, showframe]{geometry}
\usepackage{enumitem}
\usepackage{fancybox}
\usepackage{varwidth}
\begin{document}

\shadowbox{%
  \begin{varwidth}{\dimexpr\linewidth-2\fboxsep-\shadowsize-\parindent\relax}
    \begin{enumerate}[before=\itshape,wide = 0pt, font=\normalfont,label=\textbf{ABC.\arabic*}]
      \item Item 1\setcounter{enumi}{99}
      \item Item 2 \emph{This one’s a very long item. This one’s a very long item. This one’s a very long item. This one’s a very long item.}
      \item Item 3
    \end{enumerate}
  \end{varwidth}
}
\vskip1cm
\noindent\shadowbox{%
  \begin{varwidth}{\dimexpr\linewidth-2\fboxsep-2\shadowsize\relax}
    \begin{enumerate}[before=\itshape,wide = 0pt, font=\normalfont, leftmargin =*, label=\textbf{ABC.\arabic*},widest =999]
      \item Item 1\setcounter{enumi}{99}
      \item Item 2. \emph{This one’s a very long item. This one’s a very long item. This one’s a very long item. This one’s a very long item.}
      \item Item 3
    \end{enumerate}
  \end{varwidth}
}
\vskip1cm
\noindent\shadowbox{%
  \begin{varwidth}{\dimexpr\linewidth-2\fboxsep-\shadowsize\relax}
    \begin{enumerate}[before=\itshape,wide = 0pt, font=\normalfont, leftmargin =*, label=\textbf{ABC.\arabic*},widest =999]
      \item Item 1\setcounter{enumi}{99}
      \item Item 2. \emph{This one’s a very long item. This one’s a very long item. This one’s a very long item. This one’s a very long item.}
      \item Item 3
    \end{enumerate}
  \end{varwidth}
}
\end{document}

  • You're welcome. Glad to help! – Bernard Sep 28 '15 at 0:18
  • Sorry, I found one more issue. If you put display equations in the items of the list, the last equation in your list gets aligned left instead of center. – Mathemanic Sep 28 '15 at 0:38
  • Here's a demo showing what I mean: sharelatex.com/project/56088acb379fa8ec2a255224 – Mathemanic Sep 28 '15 at 0:38
  • Also, putting \begin{center} ... \end{center} around it doesn't fix it. – Mathemanic Sep 28 '15 at 0:56
  • I'll see that tomorrrow, but note if you use minipage instead of varwidth there seems to be no problem. – Bernard Sep 28 '15 at 1:56

Here's a breakable version with tcolorbox as an alternative:

\documentclass[letterpaper,10pt,american]{article}
\usepackage[left=1 in, right=1 in, top=1 in, bottom=1 in]{geometry}
\usepackage{amsmath,amsfonts,amssymb,amsthm,color,enumitem}


\usepackage{setspace}
\usepackage{caption}
\usepackage{pgf,tikz}
\usetikzlibrary{automata,arrows,positioning,calc,decorations.pathreplacing}
%\usepackage{fancybox}
\usepackage[most]{tcolorbox}
\usepackage{xpatch}

\newtcolorbox{enumshadebox}[1][]{breakable, enhanced jigsaw,sharp corners, colframe=black,drop shadow,boxsep=5pt,#1}
\usepackage{hyperref}



\begin{document}

\begin{enumshadebox}
\begin{enumerate}[leftmargin=50pt,before=\itshape,font=\normalfont,label=\textbf{ABC.\arabic*},widest={ABC.100}]
\foreach \x in {1,...,60} {%
  \item \x
}
\end{enumerate}
\end{enumshadebox}

\end{document}

  • This is another great option. Thank you, Christian! – Mathemanic Sep 28 '15 at 0:16

You have to use enumerate inside a minipage. If you want a tight box, use varwidth package. Use leftmargin=* in addition.

\documentclass[letterpaper,10pt]{article}
\usepackage[left=1 in, right=1 in, top=1 in, bottom=1 in]{geometry}
\usepackage{enumitem}
\usepackage{fancybox}
\usepackage{varwidth}
\begin{document}
\shadowbox{%
\begin{varwidth}{\linewidth}
\begin{enumerate}[before=\itshape,leftmargin=*,font=\normalfont,label=\textbf{ABC.\arabic*}]
\item Item 1
\item Item 2
\item Item 3
\end{enumerate}
\end{varwidth}
}
\end{document}

  • Thank you for your answer @HarishKumar. There are 2 problems. The first problem is, when you have ten or more items in the list, then ABC.10, ABC.11, ABC.12, etc. will leak outside of the box. The second problem is, varwidth doesn't seem to work with the hyperref package. See demo here: sharelatex.com/project/56077096379fa8ec2a25302a – Mathemanic Sep 27 '15 at 6:22
  • @EthanAlvaree Adjsut the \fboxsep: \setlength{\fboxsep}{2em} for example. – user11232 Sep 27 '15 at 6:31
  • Where in the code should that go? – Mathemanic Sep 27 '15 at 6:33
  • @EthanAlvaree: \shadowbox{% \setlength{\fboxsep}{2em} \begin{varwidth}{\linewidth} – user11232 Sep 27 '15 at 6:34
