itemize

Itemize is a LaTeX environment used to create bulleted lists. It is part of standard LaTeX and is commonly used in articles, reports, and books. To build a list, place items between \begin{itemize} and \end{itemize}, with each item introduced by the \item command.

Nested itemize environments allow sublists. For example, inside an \item you can start another \begin{itemize}...\end{itemize} block to create a sublist. LaTeX automatically adjusts the bullet style for each nesting level, with the most common pattern being a bullet at the first level and different symbols at deeper levels, depending on the font and document class.

Customization options exist to control the appearance of list labels. By using \item[<label>] within an itemize environment, a single item can display a custom label, such as \item[--] or \item[$\star$]. More extensive customization is provided by the enumitem package, which can change labels, indentation, spacing, and the overall layout of lists.

Relation to other list types: itemize creates unordered lists, in contrast to the enumerate environment, which produces numbered lists, and the description environment, which formats items as terms with descriptions. The itemize environment is typically used when the order of items is not important.

Usage notes: Itemize works with LaTeX2e and later and is widely supported across document classes such as article, report, and book. While it is specific to LaTeX, the concept of bulleted lists is common across word processors and markup languages, including HTML with ul and li elements.
