Oh, I see now. It is called "hierarchical menu" or more colloquially
"multi-level menu". For menu opening down it is also often called
"drop down menu". Physically these are sets of HTML elements (DIV, LI
etc) with display properties changing dynamically by JavaScript in
response to mouse events.
Moving the mouse over the word "Services" in the left-hand column brings
up
a submenu.
