<p>An item in the <b>Options</b> menu can be a submenu title, leading to additional
choices that are displayed in another pop-up window (on top of the Options
menu pop-up window) as a submenu.</p>
<fig id="GUID-FD9FBC91-7A38-4A26-A8C2-A478DA9D5184">

</fig>
<p>The submenu is opened by pressing either the left softkey (<b>Select</b>),
the Selection key, or the Arrow right key.</p>
<p>The user can close the submenu window by pressing the Arrow left key. The
main menu window remains open, with the focus on the submenu title.</p>
<p>When an item in a submenu is selected, both the submenu and main menu windows
are closed.</p>
<p>The following rules apply to submenus:</p>
<ul>
<li><p>The number of items should be low, so that the user does not need to
scroll in order to see all of them. </p></li>
<li><p>Functions should not occur sometimes in the main level and at other
times in a submenu. Items that are in a submenu should always be found in
the same submenu. </p></li>
<li><p>Only one submenu level is allowed; that is, a submenu cannot contain
another submenu.</p></li>
</ul>
