### 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.

## Usage

Check the `CodeExampleX.js` provided in the repository.

## Building

You can build the project with :

```sh
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 :

```sh
yarn build && yarn link
```

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

```sh
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`

Note : NWB will automatically publish it upon detecting the version bump in package.json.

## Known bugs

- keyboard-focus handling combined with optgroups and autocompleted results

## TodoList

- [x] implement select all and reset, for multiple mode

- [x] 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

- [x] add proptypes checking for value and children

- [x] support of \<optgroup />
- [ ] implement selectable \<optgroup /> to select all inner children

- [x] check rendering performance with 200 MenuItems (integrate react-infinite)

- [x] implement the container for errors (absolutely positioned below the focusedLine)

  Expose more props :

  - [x] noMatchFound message
  - [x] floatingLabelText
  - [x] canAutoPosition
  - [x] checkPosition
  - [x] anchorOrigin
  - [x] popoverStyle
  - [x] hoverColor
  - [x] disabled
  - [ ] required
  - [x] errorMessage
  - [x] errorStyle
  - [ ] classeNames for sub-components
  - [ ] maxSelection

- [x] add props.disableAutoComplete (default: false), or a nbItems2showAutocomplete (default: null, meaning never show the searchTextField)
- [x] make Autocomplete appears only if current numberOfMenuItems > props.autocompleteTreshold

- [x] implement a checkboxRenderer for MenuItem (or expose 2 properties CheckIconFalse & CheckIconTrue)
- [x] make a PR reimplementing MenuItem.insetChildren replaced with checkPosition={'left'(default) or 'right'}

- [ ] add an example with GooglePlaces
- [ ] add an example with ReduxForm
