+Selections</h1>
+
+ <div>
+
+ <p>
+
+ Selection of one or more options from a set of options is one of the most common
+ use cases in a user interface. The WRTKit supports this use case with two
+ controls, SelectionList and SelectionMenu, each of which can be in either
+ "single selection" or "multiple selection" mode. The two controls differe only
+ in look and interaction but not in their APIs.
+ </p>
+
+ <p>
+
+ The SelectionList control shows an expanded list of all of its options in the
+ view. If the control is in single selection mode then each option is presented
+ with a "radio button", of which only one can be selected at a time. This ensures
+ that only one of the options can be selected by the user. If the SelectionList
+ control is in multiple selection mode then each option is presented with a
+ "checkbox". Any amount (including zero) of checkboxes can be checked at time,
+ allowing users to select multiple options. The SelectionList control is a hybrid
+ between the traditional way of showing radio buttons and checkboxes in a web
+ environment and the way that an S60 application shows single and multiple choice
+ selections. The SelectionList is recommeded to be used when the widget is using
+ the pointer navigation mode or when there are only a few options.
+ </p>

+ </div>
+
+ <p>
+
+ The SelectionMenu control is more similar to the way normal S60 applications
+ allow users to make single or multiple choices. The SelectionMenu takes up only
+ minimally of space in its normal state, but when activated it pops up up a list
+ of options with either radio buttons (for single selection) or checkboxes (for
+ multiple selection) that the user can select. The SelectionMenu control is good
+ for the tab navigation mode or if there are many options that would use up lots
+ of space on the screen using the SelectionList control.

+
+ <p>
+
+ Options in the selection controls are specified as an array of JavaScript
+ objects, where each object represents one option. Each option object has two
+ properties: value and text. The value property can be any JavaScript value,
+ including object references and is used to represent the concrete value of the
+ option. The text property is used to display the option in the user interface.
+ The value could for example be a boolean true or false while the
+ text could be "Yes" or "No".
+ </p>
+
+ <p>
+
+ The set of currently selected options can be set or retrieved from a selection
+ control using getter and setter methods. For single selection controls the
+ selected option is specified as a single reference to one of the options in the
+ control. For multiple selection the selected options are specified as an array
+ of references to zero or more of the options in the control. Note that the
+ references to the options must refer to the very same options that are in the
+ control - not other instances of the options even if they are identical in value
+ and/or text.
+ </p>
+
+ <p>
+
+ Selection controls fire "SelectionChanged" events when the user makes a
+ selection in the control.
