Installation

This component requires 3 dependencies :

• react
• react-dom
• material-ui

... so make sure they are installed in your project.

yarn add material-ui-superselectfield

ES5 version

import SelectField from '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 or node	'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.
withResetSelectAllButtons	bool	false	Paired with 'multiple', shows an header containing the 'RESET' and 'SELECT ALL' buttons.

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.

Styling properties

Name	Type	Default	Description
autocompleteStyle	object		Allows to change the styles of the auto-complete field (inner input component). Notice: margins left/right and width of the autocomplete root element are not customisable, (automatically calculated)
autocompleteUnderlineStyle	object		Allows to change the styles of the searchTextField's underline.
autocompleteUnderlineFocusStyle	object		Allows to change the styles of the searchTextField's underline when focused.
checkedIcon	SVGicon	see below	The SvgIcon to use for the checked state. This is useful to create icon toggles.
dropDownIcon	SVGicon	see below	The SvgIcon to use for the drop down icon in the select.
errorStyle	object	{color: 'red'}	Allows to change the style of error message's container. Will resolve only if errorText is defined.
floatingLabelStyle	object		Allows to change the styles of the floating label.
floatingLabelFocusStyle	object		Allows to change the styles of the floating label when focused.
innerDivStyle	object	{}	Styles applied to the inner div of MenuItems hosting each of your children components.
hoverColor	string	'rgba(69, 90, 100, 0.1)'	Overrides the hover background color.

The menu width will always set its width to the highest value between popoverWidth prop(in px) or the root component width. The default value 180px were chosen so that the header's inner buttons don't overflow.
resetButton	node	see below	Node used to deselect all options. /!\ Requires withResetSelectAllButtons.
selectAllButton	node	see below	Node used to select all options. /!\ Requires withResetSelectAllButtons.
selectedMenuItemStyle	object		Styles to be applied to the selected MenuItem.

Building

You can build the project with :

git clone https://github.com/Sharlaan/material-ui-superselectfield.git
yarn && yarn start

It should open a new page on your default browser @ localhost:3000

Linking in another local project

To test changes on a local build of SSF :

yarn build && yarn link

... then navigate into your local project directory, and type :

yarn link material-ui-superselectfield

/!\ Warning : if you reinstall dependencies in your project, this will break the link, you will have to re-link SSF.

Tests

yarn test

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

TodoList

• implement select all and reset, for multiple mode

• 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 />

• implement selectable <optgroup /> to select all inner children

• 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
  • classeNames for sub-components
  • maxSelection

• 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

• add an example with ReduxForm
