+<p><strong>Description:</strong></p>
+<p>The <code>onSelect</code> property of the <a href="GUID-111DE423-9C84-4E4B-A45E-15081FE2A30D.html#GUID-111DE423-9C84-4E4B-A45E-15081FE2A30D"><code>MenuItem</code></a> object is an event handler for the event of when the menu item is selected.
+In other words, when the end user opens the options menu and selects a menu
+item either from the top-level menu list or from a submenu list, the system
+will fire an event and a widget can catch the event by providing a callback
+function.</p>
+<p>The callback function is passed with an argument, which is an integer
+identifier identifying the menu item that was just selected. </p>
+<p>It is possible to assign an individual callback function for each menu
+item so that the <code>id</code> argument can be ignored.</p>
+<p><strong>Syntax:</strong></p>
+<pre class="codeblock" id="GUID-0A790E5F-77BF-437D-A0BF-2D859FB63D32">MenuItem.onSelect = function(Integer id) { }</pre>
+<p>or</p>
+<pre class="codeblock" id="GUID-34A713EA-E992-4944-8A88-08FD4F1DE666">MenuItem.onSelect = onMenuItemSelected;</pre>

+{
+ // ...
+}</pre>
+<p><strong>Remarks:</strong></p>
+<p>Submenu item's callback function must be assigned to the <code>onSelect</code> property
+after the parent menu item is appended to the main menu pane.</p>
+<p>For more general information on constructing an options menu, see <a href="GUID-94946735-D23B-49C6-BB65-8BE31737AE42.html#GUID-94946735-D23B-49C6-BB65-8BE31737AE42">Using softkeys</a>.</p>
