enumsub - Aligned inline sublists for enumitem

Overview

The enumsub package provides seamless integration between enumitem and inline sublists with perfect alignment and automatic numbering. It solves the common alignment inconsistencies that occur when trying to combine enumitem and tasks packages.

Features

• Perfect alignment of inline sub-items with dynamic label styling
• Multiple numbering schemes (Roman, alphabetic, Arabic)
• Customizable spacing and dimensions
• Easy-to-use semicolon-separated syntax
• Non-breaking inline layout with consistent spacing
• Multiple convenience aliases
• Automatic counter reset at each \item

Quick Start

\documentclass{article}
\usepackage[roman]{enumsub}  % Options: roman, alpha, arabic

\begin{document}
\begin{enumerate}
  \item Main question
  \begin{enumerate}
    \item \enumsub{yes; no; maybe}
    \item \enumsub{option A; option B}
  \end{enumerate}
\end{enumerate}
\end{document}

Installation

makeindex -s gglo.ist -o enumsub.gls enumsub.glo
pdflatex enumsub.dtx
pdflatex enumsub.dtx

Package Options

Commands

Main Command

• \enumsub{item1; item2; item3} - Creates aligned inline sublists

Aliases

• \subparts{...} - Same as \enumsub
• \AutoSubpartsAligned{...} - Same as \enumsub
• \inlineparts{...} - Same as \enumsub

Customization

• \setenumsublabelwidth{width} - Adjust label column width
• \setenumsubitemwidth{width} - Adjust item column width

Predefined Styles

• mainq - Main question style
• subq - Sub-question style

Examples

Basic Usage

\begin{enumerate}[label=\textbf{\arabic*.}]
  \item What is your favorite color?
  \begin{enumerate}[label=\textbf{(\alph*)}]
    \item \enumsub{red; blue; green}
    \item \enumsub{yellow; purple}
  \end{enumerate}
\end{enumerate}

With Different Numbering

\usepackage[alpha]{enumsub}
% Now \enumsub produces (a), (b), (c) instead of (i), (ii), (iii)

Custom Spacing

\setenumsublabelwidth{3em}
\setenumsubitemwidth{2cm}
\enumsub{longer option 1; longer option 2}

Problem Solved

This package specifically addresses the alignment issues when combining enumitem and tasks:

Before (misaligned):

1. Question
   (a) option 1    option 2
       ↑ misaligned with enumitem labels

After (perfectly aligned):

1. Question
   (a) (i) option 1    (ii) option 2
       ↑ perfect alignment maintained
