/**
* Set of radio buttons designed to emulate a dropdown.
2014-08-15 08:53:05 +02:00
*
* This field allows you to ensure that a form element is submitted is not optional and is part of a fixed set of
* data. This field uses the input type of radio. It's a direct subclass of {@link DropdownField},
* so the constructor and arguments are in the same format.
2014-08-15 08:53:05 +02:00
*
* <b>Usage</b>
2014-08-15 08:53:05 +02:00
*
* <code>
* new OptionsetField(
* $name = "Foobar",
* $title = "FooBar's optionset",
* $source = array(
* "1" => "Option 1",
* "2" => "Option 2",
* "3" => "Option 3",
* "4" => "Option 4",
* "5" => "Option 5"
* ),
* $value = "1"
* );
* </code>
2014-08-15 08:53:05 +02:00
*
* You can use the helper functions on data object set to create the source array. eg:
*
* <code>
* //Database request for the object
* $map = FooBar::get()->map();
2016-09-09 08:43:05 +02:00
* // returns a Map object containing an array of ID => Title
*
2014-08-15 08:53:05 +02:00
* // Instantiate the OptionsetField
* $FieldList = new FieldList(
* new OptionsetField(
* $name = "Foobar",
* $title = "FooBar's optionset",
* $source = $map,
* $value = $map[0]
* )
* );
*
* // Pass the fields to the form constructor. etc
* </code>

*
* @see CheckboxSetField for multiple selections through checkboxes instead.
* @see DropdownField for a simple <select> field with a single element.
* @see TreeDropdownField for a rich and customizeable UI that can visualize a tree of selectable elements
