    32                 The SelectionMenu class is an implementation of a selection control that lets
       
    33                 users select options from a popup menu.
       
    34             </p>
       
    35 
       
    36             <p>
       
    37 
       
    38                 The SelectionMenu control has two modes: a display mode and a selection mode.
       
    39                 Normally the display mode is shown and users can see what the currently selected
       
    40                 options are. When a user selects the control a menu pops up that displays the
       
    41                 available options. The user can then select the option (or options) from this
       
    42                 menu. After the selection is done the menu goes away and the control returns to
       
    43                 display mode. The SelectionMenu control is useful in situations where there
       
    44                 are many options and showing them all uses up too much space.

   118                                 in the UIElement class that this control inherits from. Useful for example to
       
   119                                 identify the source of an event in event callback functions or to apply a CSS

   152                                 An array of options that the selection menu should display to the user.
       
   153                                 If the argument is omitted or null the control will not display any 
       
   154                                 options. The options can be set or changed later by calling setOptions().
       
   155                                 Options are objects with two properties: value and text. Use JavaScript
       
   156                                 object notation (JSON) to construct option objects, e.g.
       
   157                                 <samp class="codeph">
       
   158 { value: "value here", text: "Text for value goes here" }</samp>.
       
   159                                 The text value is an XHTML string.

   173 
       
   174                                 The multipleSelection argument is a boolean flag that determines whether
       
   175                                 the control should be in multipleSelection mode or not. Use true to put
       
   176                                 the control in multiple selection mode and false to put it in single
       
   177                                 selection mode. If this argument is omitted the control will go to single
       
   178                                 selection mode by default.

   192 
       
   193                                 The selected argument specifies which of the options should be selected at
       
   194                                 creation time. For multiple selection controls this should be given as an
       
   195                                 array of option objects with an empty array if no options should be selected.
       
   196                                 For single selection controls this should be the single option object that
       
   197                                 should be selected or null if no option should be selected. If the argument
       
   198                                 is omitted or null no options will be selected.
