You can produce lists in HTML that are either numbered or bulleted. Combined with CSS they can also be used to produce a horizontal menu.
Lists use the <ul> or <ol> tag. To find out how to make a horizontal menu there is some good examples here.
A simple example of an unordered (bulleted) list would be:
- One
- Two
<ul> <li>One</li> <li>Two</li> </ul>
A simple example of an ordered (numbered) list would be:
- One
- Two
<ol> <li>One</li> <li>Two</li> </ol>
