Maximum nesting level of lists in Latex

Question

Is there a way to increase the maximum nesting level of lists (enumerate, etc) in Latex? I need five levels for a class, and Google isn't finding me anything...

Answer 1

Solution using enumitem package

1. If you do not have the version 3 of the enumitem.sty installed, then download enumitem.sty manually and place it into your project's folder.
2. For itemize lists, add the following to the preamble of your document:

 \usepackage{enumitem} \setlistdepth{9}  \setlist[itemize,1]{label=$\bullet$} \setlist[itemize,2]{label=$\bullet$} \setlist[itemize,3]{label=$\bullet$} \setlist[itemize,4]{label=$\bullet$} \setlist[itemize,5]{label=$\bullet$} \setlist[itemize,6]{label=$\bullet$} \setlist[itemize,7]{label=$\bullet$} \setlist[itemize,8]{label=$\bullet$} \setlist[itemize,9]{label=$\bullet$}  \renewlist{itemize}{itemize}{9} 

For the other list types this has to be adapted.

Troubleshooting help

• if you get "! Undefined control sequence. \setlistdepth", the version of enumitem.sty that LaTeX uses is older then version 3.
• if you still get the "Too deeply nested" error, then the renewlist command is missing for the list type you use
• if you get "Package enumitem Error: Undefined label.", then the label for one of the levels was not definied with the \setlist[itemize,$LEVEL] ... command

Answer 2

You can use the enumitem package. After what you just have to put the depth level you want:

\usepackage{enumitem} ... \setlistdepth{9} 

And you can have up to 9 nested levels for your lists, easy ;-)

This feature is available in the package since 3.0 (Ubuntu installed me the 2.2 for instance). In case where you have an old version just replace it by: http://ctan.mackichan.com/macros/latex/contrib/enumitem/enumitem.sty

Hope that helps!
