# lyx 3 column document

I am using LyX and would like to create a document with 3 vertical columns. I noticed there was a built-in option for 2 columns, i.e. Document->Settings->Text Layout->Two-column document. Is there an option for 3 columns? If not, is it possible to create it with a LaTeX preamble? (at the beginning of the LyX document)

You can use the multicol package. You need to add

\usepackage{multicol}


to the LaTeX preamble (Document -> Settings -> LaTeX preamble).

You also need to insert two lines of ERT

\begin{multicols}{3}


and

\end{multicols}


Everything between these two is now in a three-column layout.
