    Summary

    The HTML unordered list element (<ul>) represents an unordered list of items, namely a collection of items that do not have a numerical ordering, and their order in the list is meaningless. Typically, unordered-list items are displayed with a bullet, which can be of several forms, like a dot, a circle or a squared. The bullet style is not defined in the HTML description of the page, but in its associated CSS, using the list-style-type property.

    There is no limitation to the depth and imbrication of lists defined with the <ol> and <ul> elements.

    Usage note: The <ol> and <ul> elements both represent a list of items. They differ in that, with the <ol> element, the order is meaningful. As a rule of thumb to determine which one to use, try changing the order of the list items; if the meaning is changed, the <ol> element should be used, otherwise you can use <ul>.

    Usage context

    Attributes

    This element includes the global attributes.

    compact
    This Boolean attribute hints that the list should be rendered in a compact style. The interpretation of this attribute depends on the user agent and it doesn't work in all browsers.
    Usage note: Do not use this attribute, as it has been deprecated: the <ul> element should be styled using CSS. To give a similar effect as the compact attribute, the CSS property line-height can be used with a value of 80%.
    type
    Used to set the bullet style for the list. The values defined under HTML3.2 and the transitional version of HTML 4.0/4.01 are:
    • circle,
    • disc,
    • and square.

    A fourth bullet type has been defined in the WebTV interface, but not all browsers support it: triangle.

    If not present and if no CSS list-style-type property does apply to the element, the user agent decide to use a kind of bullets depending on the nesting level of the list.

    Usage note: Do not use this attribute, as it has been deprecated; use the CSS list-style-type property instead.

        <ul>
          <li>second item first subitem</li>
          <li>second item second subitem      <!-- Same for the second nested unordered list! -->
            <ul>
              <li>second item second subitem first sub-subitem</li>
              <li>second item second subitem second sub-subitem</li>
              <li>second item second subitem third sub-subitem</li>
            </ul>
          </li>           <!-- Closing </li> tag for the li that contains the third unordered list -->
          <li>second item third subitem</li>
        </ul>
      </li>               <!-- Here is the closing </li> tag -->
      <li>third item</li>
    </ul>

    Above HTML will output:

    • first item
    • second item
      • second item first subitem
      • second item second subitem
        • second item second subitem first sub-subitem
        • second item second subitem second sub-subitem
        • second item second subitem third sub-subitem
      • second item third subitem
    • third item

    Nested <ul> and <ol>

    <ul>
      <li>first item</li>
      <li>second item      <!-- Look, the closing </li> tag is not placed here! -->
        <ol>

          <li>second item second subitem</li>
          <li>second item third subitem</li>
        </ol>
      </li>                <!-- Here is the closing </li> tag -->
      <li>third item</li>
    </ul>
    

    Above HTML will output:

    • first item
    • second item
      1. second item first subitem
      2. second item second subitem
      3. second item third subitem
    • third item

      • the list-style property, useful to choose the way the ordinal is displayed,
      • CSS counters, useful to handle complex nested lists,
      • the line-height property, useful to simulate the deprecated compact attribute,
      • the margin property, useful to control the indent of the list.
