# LyX enumeration style from numbers to letters

I'd like to use, for this specific instance, letter style enumeration [ like a) b) c) ] . I realize that I can nest one enumerate environment in another and the style will change, but I don't want a dangling "1." from the topmost enumerate environment.

-

Write into `Document->Settings->Preamble`:

``````\usepackage{enumitem}
\setenumerate{label=A)}
\setenumerate[2]{label=a)}
``````

For deeper values use also [3], [4]. Inside LyX you will still see the 1. If you want to change this too, then you'll have to rewrite your LyX layout file.

Thanks for the answer. Is there a way to have these settings apply to a specific enumerate environment? For example, in one part of the document I want the highest level symbol to be letters, and in another part of the document I want the highest level symbol to be numbers. – Gus Mar 23 '11 at 15:42
yes @Gus, see my answer. you'll need to use `\renewcommand` repeatedly. – Sparkler Nov 21 '14 at 22:40

• To get `a)`, add this to the preamble: `\renewcommand{\labelenumi}{\alph{enumi})}`
• To get `[a]`, add this to the preamble: `\renewcommand{\labelenumi}{[\alph{enumi}]}`

If you don't want the change to occur globally, then add this code right before the enumeration (and resotre right after, if needed).

In the preamble, use the `\renewcommand{indicator}{format}` syntax for each level of heirarchy you would like to change (4 level max. are supported), where indicator is either of the following label indicators:

1. `\labelenumi` -- 1st level
2. `\labelenumii` -- 2nd level
3. `\labelenumiii` -- 3rd level
4. `\labelenumiv` -- 4th level

and format is a macro consisting of enumerators and styles.

The style can be any of the following:

• `\arabic{enumerator}`, for 1, 2, 3, ...
• `\alph{enumerator}`, for a, b, c, ...
• `\Alph{enumerator}`, for A, B, C, ...
• `\roman{enumerator}`, for i, ii, iii, ...
• `\Roman{enumerator}`, for I, II, III, ...

The enumerator can be any of the following:

1. `enumi` -- 1st level
2. `enumii` -- 2nd level
3. `enumiii` -- 3rd level
4. `enumiv` -- 4th level

I personally prefer the `1.4.2 a)` repeating format, for which you need:

``````\renewcommand{\labelenumi}{\arabic{enumi}.}
\renewcommand{\labelenumii}{\labelenumi\arabic{enumii}.}
\renewcommand{\labelenumiii}{\labelenumii\arabic{enumiii}}
\renewcommand{\labelenumiv}{\alph{enumiv})}
``````

Use the default "Numbered list" [^P E], then ctrl+click over a list element. Select "Custom Item". You will see the default symbols but you will get also a "Custom Item" box:

``````1. Custom Item [A]Fruits:

a) Custom Item [A.1] orange

b) Custom Item [A.2] apple
``````

will produce:

A Fruits:

A.1 orange

A.2 apple

Welcome to TeX.SX! You can have a look at our starter guide to familiarize yourself further with our format. – Pier Paolo Jan 21 '15 at 20:07

in preamble

``````\renewcommand{\theenumi}{\alph{enumi}}
\renewcommand{\theenumii}{\arabic{enumii}}
\renewcommand{\labelenumii}{\theenumii.}
``````
