##Installation npm i material-ui-superselectfield

This component requires 4 dependencies :

• react-dom
• react-tap-event-plugin

... so make sure they are installed in your project, or install them as well ;)

disabled	bool	false	Include this property to disable superSelectField.
value	null, object, object[]	null	Selected value(s). /!\ REQUIRED: each object must expose a 'value' property.
onChange	function		Triggers when selecting/unselecting an option from the Menu. signature: (selectedValues, name) with selectedValues array of selected values based on selected nodes' value property, and name the value of the superSelectField instance's name property
children	any	[]	Datasource is an array of any type of nodes, styled at your convenience. /!\ REQUIRED: each node must expose a value property. This value property will be used by default for both option's value and label. A label property can be provided to specify a different value than value.

#####Note when setting value :
if multiple is set, value must be at least an empty Array.
For single value mode, you can set value to null.
When using objects, make sure they expose a non-null value property.
PropTypes should raise warnings if implementing otherwise.

Known bugs

• keyboard-focus handling

TodoList

• set autoWidth to false automatically if width prop has a value

• add a css rule for this.root :focus { outline: 'none' }, and :hover { darken }

• add tests for focus states/styles when tabbing between multiple superSelectFields

• add tests for keystrokes

• add proptypes checking for value and children

• support of <optgroup />

• check rendering performance with 200 MenuItems (integrate react-infinite)

• implement the container for errors (absolutely positioned below the focusedLine)

  Expose more props :

  • noMatchFound message
  • floatingLabelText
  • canAutoPosition
  • anchorOrigin
  • popoverStyle
  • hoverColor
  • disabled
  • required
  • errorMessage
  • errorStyle

• add props.disableAutoComplete (default: false), or a nbItems2showAutocomplete (default: null, meaning never show the searchTextField)

• make Autocomplete appears only if current numberOfMenuItems > props.autocompleteTreshold

• implement a checkboxRenderer for MenuItem (or expose 2 properties CheckIconFalse & CheckIconTrue)

• make a PR reimplementing MenuItem.insetChildren replaced with checkPosition={'left'(default) or 'right'}

• add an example with GooglePlaces
