How to make horizontal lists?
The enumitem package has an inline option which implements inline versions of the standard lists using starred versions of the basic list environments. As with other enumitem lists, labels and (horizontal) spacing can be set with key values as well as custom settings for the elements between the list items (typically punctuation).
\documentclass{article}
\usepackage[inline]{enumitem}
\begin{document}
Text before list.
\begin{enumerate*}
\item My first in list.
\item My second in list.
\end{enumerate*}
Text after list.
\end{document}
If you use the enumitem package, you can pass the option [inline]. Doing this enables starred environments corresponding to the regular ones which produce inline lists (\begin{enumerate*}, \begin{itemize*} etc.):
\documentclass{article}
\usepackage[inline]{enumitem}
\begin{document}
Text before list.
\begin{enumerate*}[label=(\roman*)]
\item My first in list.
\item My second in list.
\end{enumerate*}
Text after list.
\end{document}
This package gives you a lot of control over the formatting of enumerate, itemize and description environments and lets you control their style globally or locally, to create custom environments based on the defaults, and to easily specify a range of formatting options. The above example produces an inline enumerated list with labels of the form (i). What I actually do is set up a customised environment for this so that I can use it as I wish:
\newlist{mylist}{enumerate*}{1}
\setlist[mylist]{label=(\roman*)}
Then I can just say
\begin{mylist}
\item My first in list.
\item My second in list.
\end{mylist}
and it is easy to change the configuration globally if I need to. By changing the definition of mylist, for example, you could switch all of the lists which used this environment from vertical to inline.
