LyX ⇒ Problem with enumeration

[monemonemone]

hey! i am a lyx-starter... however it works quite well. except for a problem with enumeration.
i want to create an enumeration, looking like this
1. xxx
1.1 xxx
2. xxxx
2.1 xxxx
2.2 xx

-> that means an enumeration only consisting of numbers.

but when i create an enumeration with lyx, enumerations have letters in the second level. they look like this
1. xxx
a) xxx
b) xxx
i. xx

how can i avoid letters and put in numbers instead?

thank you VERY MUCH for your help!

Hi,

use some of the features of the enumitem package:

Code: Select all

\documentclass{article}
\usepackage{enumitem}

\begin{document}

\begin{enumerate}
  \item First item
  \begin{enumerate}[label*=\arabic*]
    \item First sub item
  \end{enumerate}
\end{enumerate}

\end{document}

hey, thanks for your answer.
but i have no idea what to do next.
how can I add this enumitem package to lyx?
thanks again!

No idea; I've never used LyX. Perhaps a LyX user can help you here.

Try going into Document > Settings, and then under "LaTeX Preamble", add:

Code: Select all

\usepackage{enumitem}
\setenumerate[2]{label*=\arabic*}

It'll still show (a) and (b), etc., in the LyX editor screen, but it should show the right thing when you export to PDF (or DVI or whatever).
