    This page deals with creating lists in Mediawiki.

    List basics

    MediaWiki offers three types of lists. Ordered lists, unordered lists, and definition lists. In the following sections, ordered lists are used for examples. Unordered lists would give corresponding results.

    * Lists are easy to do:
    ** start every line
    * with a star
    ** more stars mean
    *** deeper levels

    Paragraphs in lists

    For simplicity, list items in wiki markup cannot be longer than a paragraph. A following blank line will end the list and reset the counter on ordered lists. Separating unordered list items usually has no noticable effects.

    Paragraphs can be forced in lists by using HTML tags. Two line break symbols, <br><br>, will create the desired effect. So will enclosing all but the first paragraph with <p>...</p>

    For a list with items of more than one paragraph long, adding a blank line between items may be necessary to avoid confusion.

    Continuing a list item after a sub-item

    In HTML, a list item may contain several sublists, not necessarily adjacent; thus there may be parts of the list item not only before the first sublist, but also between sublists, and after the last one; however, in wiki-syntax, sublists follow the same rules as sections of a page: the only possible part of the list item not in sublists is before the first sublist.

    In the case of an unnumbered first-level list in wikitext code this limitation can be overcome by splitting the list into multiple lists; indented text between the partial lists may visually serve as part of a list item after a sublist; however, this may give, depending on CSS, a blank line before and after each list, in which case, for uniformity, every first-level list item could be made a separate list.

    Numbered lists illustrate that what should look like one list may, for the software, consist of multiple lists; unnumbered lists give a corresponding result, except that the problem of restarting with 1 is not applicable.

    <ol>
      <li>list item A1
        <ol>
          <li>list item B1</li>
          <li>list item B2</li>
        </ol>continuing list item A1
      </li>
      <li>list item A2</li>
    </ol>
    
    1. list item A1
      1. list item B1
      2. list item B2
      continuing list item A1
    2. list item A2
    vs.
    #list item A1
    ##list item B1
    ##list item B2
    #:continuing list item A1
    #list item A2
    
    1. list item A1
      1. list item B1
      2. list item B2
      continuing list item A1
    2. list item A2

    One level deeper, with a sublist item continuing after a sub-sublist, one gets even more blank lines; however, the continuation of the first-level list is not affected:

    #list item A1
    ##list item B1
    ###list item C1
    ##:continuing list item B1
    ##list item B2
    #list item A2
    

    gives

    1. list item A1
      1. list item B1
        1. list item C1
        continuing list item B1
      2. list item B2
    2. list item A2

    Changing the list type

    The list type (which type of marker appears before the list item) can be changed in CSS by setting the list-style-type property:

    wikitext rendering
    <ol style="list-style-type:lower-roman">
      <li>About the author</li>
      <li>Foreword to the first edition</li>
      <li>Foreword to the second edition</li>
    </ol>
    
    1. About the author
    2. Foreword to the first edition
    3. Foreword to the second edition

    Extra indentation of lists

    In a numbered list in a large font, some browsers do not show more than two digits, unless extra indentation is applied (if there are multiple columns: for each column).

    wikitext rendering comments
    :#abc
    :#def
    :#ghi
     
    
    1. abc
    2. def
    3. ghi
    A list of one or more lines starting with a colon creates a definition list without definition terms, and with the items as definition descriptions, hence indented. However, if the colons are in front of the codes "*" or "#" of an unordered or ordered list, the list is treated as one definition description, so the whole list is indented.
    <ul>
      <ol>
        <li>abc</li>
        <li>def</li>
        <li>ghi</li>
      </ol>
    </ul>
    
    
      1. abc
      2. def
      3. ghi
    MediaWiki translates an unordered list (ul) without any list items (li) into a div with a style="margin-left: 2em", causing indentation of the contents. This is the most versatile method, as it allows starting with a number other than 1, see below.
    <ul>
    #abc
    #def
    #ghi
    </ul>
    
    
      1. abc
      2. def
      3. ghi
    Like above, with the content of the "unordered list without any list items", which itself is an ordered list, expressed with # codes. The HTML produced, and hence the rendering, is the same. This is the recommended method when not starting with a number other than 1.

    Comparison with a table

    Apart from providing automatic numbering, the numbered list also aligns the contents of the items, comparable with using table syntax:

    {|
    |-
    | align=right |  9.||Amsterdam
    |-
    | align=right | 10.||Rotterdam
    |-
    | align=right | 11.||The Hague
    |}
    

    gives

    9. Amsterdam
    10. Rotterdam
    11. The Hague

    This non-automatic numbering has the advantage that if a text refers to the numbers, insertion or deletion of an item does not disturb the correspondence.

    Multi-column bulleted list

    {| 
    | 
    *1
    *2 
    | 
    *3
    *4
    |}
    

    gives:

    • 1
    • 2
    • 3
    • 4
