getItemValue: Function

Arguments: item: Any

Used to read the display value from each entry in items.

items: Array

The items to display in the dropdown menu

renderItem: Function

Arguments: item: Any, isHighlighted: Boolean, styles: Object

Invoked for each entry in items that also passes shouldItemRender to generate the render tree for each item in the dropdown menu. styles is an optional set of styles that can be applied to improve the look/feel of the items in the dropdown menu.

autoHighlight: Boolean (optional)

Default value: true

Whether or not to automatically highlight the top match in the dropdown menu.

inputProps: Object (optional)

Default value: {}

Props that are applied to the <input /> element rendered by Autocomplete. Any properties supported by HTMLInputElement can be specified, apart from the following which are set by Autocomplete: value, autoComplete, role, aria-autocomplete

menuStyle: Object (optional)

Default value:

  borderRadius: '3px',
  boxShadow: '0 2px 12px rgba(0, 0, 0, 0.1)',
  background: 'rgba(255, 255, 255, 0.9)',
  padding: '2px 0',
  fontSize: '90%',
  position: 'fixed',
  overflow: 'auto',
  maxHeight: '50%', // TODO: don't cheat, let it flow to the bottom

Styles that are applied to the dropdown menu in the default renderMenu implementation. If you override renderMenu and you want to use menuStyles you must manually apply them (this.props.menuStyles).

onChange: Function (optional)

Default value: function() {}

Arguments: event: Event, value: String

Invoked every time the user changes the input's value.

onMenuVisibilityChange: Function (optional)

Default value: function() {}

Arguments: isOpen: Boolean

Invoked every time the dropdown menu's visibility changes (i.e. every time it is displayed/hidden).

onSelect: Function (optional)

Default value: function() {}

Arguments: value: String, item: Any

Invoked when the user selects an item from the dropdown menu.

open: Boolean (optional)

Used to override the internal logic which displays/hides the dropdown menu. This is useful if you want to force a certain state based on your UX/business logic. Use it together with onMenuVisibilityChange for fine-grained control over the dropdown menu dynamics.

renderMenu: Function (optional)

Default value:

function(items, value, style) {
  return <div style={{...style, ...this.menuStyle}} children={items}/>

Arguments: items: Array<Any>, value: String, styles: Object

Invoked to generate the render tree for the dropdown menu. Ensure the returned tree includes items or else no items will be rendered. styles will contain { top, left, minWidth } which are the coordinates of the top-left corner and the width of the dropdown menu.

shouldItemRender: Function (optional)

Arguments: item: Any, value: String

Invoked for each entry in items and its return value is used to determine whether or not it should be displayed in the dropdown menu. By default all items are always rendered.

sortItems: Function (optional)

Arguments: itemA: Any, itemB: Any, value: String

The function which is used to sort items before display.

value: Any (optional)

Default value: ''

The value to display in the input field

wrapperProps: Object (optional)

Default value: {}

Props that are applied to the element which wraps the <input /> and dropdown menu elements rendered by Autocomplete.

wrapperStyle: Object (optional)

Default value:

  display: 'inline-block'

This is a shorthand for wrapperProps={{ style: <your styles> }}. Note that wrapperStyle is applied before wrapperProps, so the latter will win if it contains a style entry.
