In LyX: Skipping numbers in enumerate and changing symbol of enumeration

Question

I would like to skip numbers in a list. Consider the following example:

\begin{enumerate}
\item text1
\item[3.] text2
\item[22.] text3
\end{enumerate}

However, I cannot figure out how to do this in LyX (although it is obvious how to code it in the source code). I tried exporting, then changing and reimporting the document, however LyX doesn't properly read these changes.

A related questions is how to get the symbols in numbering to change in LyX, e.g. from 1., 2., 3., .... to i., ii., iii., ... , as shown below.

\begin{enumerate}[i]
\item text1
\item text2
\end{enumerate}

Thanks!

They are two quite different questions, but anyways.

Custom labels on items

There are at least two possibilities:

1. At the beginning of the item, add the optional argument, e.g. [22.] within an ERT.
2. Use the ``Labeling'' list type instead of Enumerate. This is a LyX-specific list that uses the first word you type as the label of the item. Of course, this means that you have to specify the number on all the items manually.

Arabic to roman

Go to Document --> Settings --> Modules, and add the Customisable lists (enumitem) module to your document. When you create a list, right click the first item, and choose Insert Short Title. Within the short title box, add an ERT, and type label=\roman*.. See the enumitem manual for more details about what you can put here.
