<SimpleSelect
    placeholder = "Select a fruit"
    onValueChange = {function(value, callback){

SimpleSelect Props

Property	Type	Description
autosize	InputElement -> Int	function($search){return $search.value.length * 10} custom logic for autosizing the input element
className	String	class name for the outer element, in addition to "simple-select"
disabled	Boolean	disables interaction with the Select control
dropdownDirection	Int	defaults to 1, setting it to -1 opens the dropdown upward
createFromSearch	[Item] -> String -> Item?	implement this function to create new items on the fly, function(options, search){return {label: search, value: search}}, return null to avoid option creation for the given parameters
filterOptions	[Item]-> String -> [Item]	implement this function for custom synchronous filtering logic, function(options, search) {return options}
groupId	Item -> b	function(item){return item.groupId} this function is used to identify which group an option belongs to, it must return a value that matches the groupId property of an object in the groups collection
groups	[Group]	collection of objects where each object must atleast have a groupId property
groupsAsColumns	Boolean	display option groups in columns
onBlur	Item -> String -> Void	function(value, reason){} reason can be either "click" (loss of focus because the user clicked elsewhere), "tab" or "blur" (invoked refs.simpleSelect.blur())
onFocus	Item -> String -> Void	function(value, reason){} reason can be either "event" (when the control gains focus outside) or "focus" (when the user invokes refs.simpleSelect.focus())
onSearchChange	String -> (a -> Void) -> Void	function(search, callback){self.setState({search: search}, callback);} or function(search,callback){callback();} i.e. callback MUST always be invoked
onValueChange	Item -> (a -> Void) -> Void	function(selectedValue, callback){self.setState({selectedValue: selectedValue}, callback)} or function(value, callback){callback()} i.e. callback MUST always be invoked
options	[Item]	list of items by default each option object MUST have label & value property, otherwise you must implement the render* & filterOptions methods
placeholder	String	displayed when there is no value
renderNoResultsFound	Item -> String -> ReactElement	function(item, search){return React.DOM.div(null);} returns a custom way for rendering the "No results found" error
renderGroupTitle	Int -> Group -> ReactElement	function(index, group){return React.DOM.div(null)} returns a custom way for rendering the group title
renderOption	Item -> ReactElement	function(item){return React.DOM.div(null);} returns a custom way for rendering each option
renderValue	Item -> ReactElement	function(item){return React.DOM.div(null);} returns a custom way for rendering the selected value
restoreOnBackspace	Item -> String	function(item){return item.label;} implement this method if you want to go back to editing the item when the user hits the [backspace] key instead of getting removed
search	String	the text displayed in the search box
style	Object	the CSS styles for the outer element
uid	(Eq e) => Item -> e	function(item){return item.value} returns a unique id for a given option, defaults to the value property
value	Item	the selected value, i.e. one of the objects in the options array

SimpleSelect methods

Method	Type	Description
focus	a -> (a -> Void) -> Void	this.refs.selectInstance.focus(callback) opens the list of options and positions the cursor in the input control, the callback fired when the options menu becomes visible
highlightFirstSelectableOption	a -> Void	this.refs.selectInstance.highlightFirstSelectableOption()
value	a -> Item	this.refs.selectInstance.value() returns the current selected item

MultiSelect Props

In addition to the props above

Property	Type	Description

createFromSearch	[Item] -> [Item] -> String -> Item?	function(options, values, search){return {label: search, value: search}}
filterOptions	[Item] -> [Item] -> String -> [Item]	function(options, values, search){return options}
onAnchorChange	Item -> (a -> Void) -> Void	function(anchor, callback){callback();} implement this method if you want to override the default behaviour of the cursor
onBlur	[Item] -> String -> Void	function(values, reason){}
onFocus	[Item] -> String -> Void	function(values, reason){}
onValuesChange	[Item] -> (a -> Void) -> Void	function(values, callback){callback();}
maxValues	Int	the maximum values that can be selected, after which the control is disabled
closeOnSelect	Boolean	as the name implies, closes the options list on selecting an option
