Schema

Property	Type	Default	Description
default	any		The default value to be assigned for this property. If the data for the field is empty or not provided, this default value will be plugged in for you. Specify a default value when you want to pre-populate the field's value ahead of time.
dependencies	array		List of property dependencies.
description	string		Detailed description of the property.
disallow	array		List of disallowed values for the property.
enum	array		List of field value options
format	string		Data format of the property.
readonly	boolean		Indicates that the field is read-only. A read-only field cannot have it's value changed. Read-only fields render in a grayed-out or disabled control. If the field is rendered using a view with the displayReadonly attribute set to false, the read-only field will not appear.
required	boolean		Indicates whether the field's value is required. If set to true, the field must take on a valid value and cannnot be left empty or unassigned.
title	string		Short description of the property.
type	string		Data type of the property.

Options

Property	Type	Default	Description
dataSource	string		Datasource for generating list of options. This can be a string or a function. If a string, it is considered S be a URI to a service that produces a object containing key/value pairs or an array of elements of structure {'text': '', 'value': ''}. This can also be a function that is called to produce the same list.
disabled	boolean		Field will be disabled if true.
fieldClass	string		Specifies one or more CSS classes that should be applied to the dom element for this field once it is rendered. Supports a single value, comma-delimited values, space-delimited values or values passed in as an array.
focus	checkbox	true	If true, the initial focus for the form will be set to the first child element (usually the first field in the form). If a field name or path is provided, then the specified child field will receive focus. For example, you might set focus to 'name' (selecting the 'name' field) or you might set it to 'client/name' which picks the 'name' field on the 'client' object.
form	object		Options for rendering the FORM tag.
height	number		Specify a fixed height for the list boxes. If not provided, the list boxes size to the amount of data.
helper	string		Field help message.
helpers	array		An array of field help messages. Each message will be displayed on it's own line.
helpersPosition	string	below	Defines the placement location of the helper text relative to the control (either 'above' or 'below')
hidden	boolean		Field will be hidden if true.
hideInitValidationError	boolean		Hide initial validation errors if true.
hideNone	boolean		Whether to hide the None option from a list (select, radio or otherwise). This will be true if the field is required and false otherwise.
id	string		Unique field id. Auto-generated if not provided.
join	function		For multiple select lists. Defines a f(a) for how selected options should be combined into a single string. A split function should also be defined which reverses this function.
label	string		Field label.
name	string		Field Name.
noneLabel	string	None	The label to use for the 'None' option in a list (select, radio or otherwise).
optionLabels	array		An array of string labels for items in the enum array
readonly	boolean		Field will be readonly if true.
removeDefaultNone	boolean		If true, the default 'None' option will not be shown.
showAllSelections	boolean		When true, show full selection list and disable anything already selected
showMessages	boolean	true	Display validation messages if true.
sort	function		Defines an f(a,b) sort function for the array of enumerated values [{text, value}]. This is used to sort enum and optionLabels as well as results that come back from any data sources (for select and radio controls). By default the items are sorted alphabetically. Don't apply any sorting if false.
split	function		For multiple select lists. Defines a f(a) for how data strings should be split into individual values. A join function should also be defined which reverses this function.
type	string	chooser	Field type.
useDataSourceAsEnum	boolean	true	Whether to constrain the field's schema enum property to the values that come back from the data source.
validate	boolean	true	Field validation is required if true.
view	string		Allows for this field to be rendered with a different view (such as 'display' or 'create')

Example 1

A simple example for a string field with enumerated values.

Example 2

An example of a string value where enumerated values are loaded from a data source.

Example 3

An example with showAllSelections set to true. This makes it so that the left-hand side always shows all values. Selected values are grayed out (or disabled).

Example 4

In this example, we set height to 90px which lets you control the amount of vertical screen real estate the control will use. This introduces scroll bars for selecting values.

Example 5

Here we show how to mount the control on top of an array.

Example 6

Here we include buttons to enable and disable the control.

Example 7

A display version of the control.

Example 8

An example where we set the value after render.

Example 9

An example using custom delimiters
