Installation

This component requires 3 dependencies :

• react
• react-dom
• material-ui

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

ES5 version

npm i material-ui-superselectfield

ES6+ version

Properties

Name	Type	Default	Description
anchorOrigin	object	{ vertical: 'top', horizontal: 'left' }	Anchor position of the menu, accepted values: top, bottom / left, right
autocompleteFilter	function	see below	Provide your own filtering parser. Default: case insensitive. The search field will appear only if there are more than 10 children (see showAutocompleteThreshold). By default, the parser will check for label props, 'value' otherwise.
canAutoPosition	bool	true	If present, this property allows the inner Popover component to position the menu in such way options are not hidden by the screen edges.
checkPosition	string		Position of the checkmark in multiple mode. Accepted values: '', left, right
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.
disabled	bool	false	Include this property to disable superSelectField.
elementHeight	number, number[]	36	Height in pixels of each option element. If elements have different heights, you can provide them in an array.
errorText	string or node	''	Include this property to show an error warning.
floatingLabel	string or node		The content to use for the floating label element.
hintText	string	'Click me'	Placeholder text for the main selections display.
hintTextAutocomplete	string	'Type something'	Placeholder text for the autocomplete.
keepSearchOnSelect	bool	false	Prevents the autocomplete field's value to be reset after each selection.
multiple	bool	false	Include this property to turn superSelectField into a multi-selection dropdown. Checkboxes will appear.
name	string		Required to differentiate between multiple instances of superSelectField in same page.
nb2show	number	5	Number of options displayed from the menu.
noMatchFound	string	'No match found'	Placeholder text when the autocomplete filter fails.
openImmediately	bool	false	Makes the menu opened on page load.
onAutoCompleteTyping	function	() => {}	Exposes the word typed in AutoComplete. Useful for triggering onType API requests.
onChange	function	() => {}	Triggers when closing the menu. Use this if you do not want to update your component state with each selection and only on menu close. 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
onMenuOpen	function	() => {}	Triggers when opening the Menu.
onSelect	function	() => {}	Triggers when selecting an item in the menu. Use this to update your componenet state with each selection from the menu (while still open). 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
showAutocompleteThreshold	number, 'always', 'never'	10	Maximum number of options from which to display the autocomplete search field. For example, if autoComplete textfield needs to be disabled, just set this prop with a value higher than children length. However, if you need the autocomplete to show always, you may pass 'always'. This will open the menu even if there are no items to display. Passing 'never' will never show the autocomplete regadless of how many children are passed.
useLayerForClickAway	bool	false	If true, the popover dropdown will render on top of an invisible layer, which will prevent clicks to the underlying elements, and trigger an onRequestClose('clickAway') call.
value	null, object, object[]	null	Selected value(s). /!\ REQUIRED: each object must expose a 'value' property.

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.

Contributing

In lieu of a formal style guide, take care to maintain the existing coding style. Add unit tests for any new or changed functionality. Lint and test your code.

Known bugs

• keyboard-focus handling combined with optgroups and autocompleted results
• dynamic heights calculation

TodoList

• implement onClose handler for multiple mode, to allow registering selected values in oneshot instead of exposing values at each selection (ie one single server request)

• 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
  • checkPosition
  • 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
