问题:

Suppose, that as part of documenting your code (Javadoc) you want to indicate that the relationships between elements using deep indentation.

How can I create a nested list as:

some element
- some other element
  - yet some other element

回答1:

<ul>
  <li>Element</li>
  <ul>
     <li>Subelement...</li>

You can pretty freely use HTML inside javadoc comments.

Update: Because it came up, I tried

<ul>
    <li>one</li>
    <ul>
        <li>one point one</li>
    </ul>   
</ul>

and get

one point one

I agree proper nesting is better.

回答2:

The nested list should be within its own <li>. <ul> is not a valid child element of <ul>.

So your example would be:

<ul>
  <li>some element</li>
  <li>
    <ul>
      <li>some other element</li>
      <li>
        <ul>
          <li>yet some other element</li>
        </ul>
      </li>
    </ul>
  </li>
</ul>

回答3:

The correct way is as follows:

/**
 * <ul>
 *   <li>some element
 *   <li><ul>
 *     <li>some other element
 *     <li><ul>
 *       <li>yet some other element
 *     </ul>
 *   </ul>
 * </ul>
 */

Although JavaDoc borrows from HTML, it isn't HTML, and you should omit the </li> tags, just as you should omit </p> tags.
