API Reference

The components and higher-order components (HOCs) described below are publicly exposed in the top-level module. Other components should be considered private and subject to change without notice.

Components

Only a subset of props are documented below, primarily those expecting functions. See the props documentation for the full list of options.

<Typeahead>

The primary component provided by the module.

Props

filterBy

See full documentation in the Filtering section.

labelKey, renderMenu, renderMenuItemChildren, and renderToken

See full documentation in the Rendering section.

onChange(selectedItems)

Invoked when the set of selections changes (ie: an item is added or removed). For consistency, selectedItems is always an array of selections, even multi-selection is not enabled.

onInputChange(text)

Invoked when the input value changes. Receives the string value of the input (text).

onPaginate(event)

Invoked when the pagination menu item is clicked. Receives an event.

onBlur(event) & onFocus(event)

As with a normal text input, these are called when the typeahead input is focused or blurred.

<AsyncTypeahead>

An enhanced version of the normal Typeahead component for use when performing asynchronous searches. Provides debouncing of user input, optional query caching, and search prompt, empty results, and pending request behaviors.

<AsyncTypeahead
  onSearch={query => (
    fetch(`https://api.github.com/search/users?q=${query}`)
      .then(resp => resp.json())
      .then(json => this.setState({options: json.items}));
  )}
  options={this.state.options}
/>

Note that this component is the same as:

import {asyncContainer, Typeahead} from 'react-bootstrap-typeahead';

const AsyncTypeahead = asyncContainer(Typeahead);

Props

onSearch(query) (required)

Callback to perform when the search is executed. query is the text string entered by the user.

<Menu>

Provides the markup for a Bootstrap menu, along with some extra functionality for alignment, paginating results, and specifying empty label text.

<MenuItem>

Provides the markup for a Bootstrap menu item, but is wrapped with the menuItemContainer HOC to ensure proper behavior within the typeahead context. Provided for use if a more customized Menu is desired.

Props

option (required)

The data item to be displayed.

position

The position of the data item within the data set. This allows you to reorder or group your data within renderMenu while allowing the top-level Typeaheadcomponent to be be aware of this. Required for proper highlighting of menu items when keying through the menu.

<Token>

Individual token component, most commonly for use within renderToken to customize the Token contents.

Higher-Order Components

asyncContainer

The HOC used in AsyncTypeahead.

menuItemContainer

Connects individual menu items with the main typeahead component via context and abstracts a lot of complex functionality required for behaviors like keying through the menu and input hinting. Also provides onClick behavior and active state.

If you use your own menu item components (in renderMenu for example), you are strongly advised to wrap them with this HOC:

import {MenuItem} from 'react-bootstrap';
import {Menu, menuItemContainer, Typeahead} from 'react-bootstrap-typeahead';

const TypeaheadMenuItem = menuItemContainer(MenuItem);

<Typeahead
  renderMenu={(results, menuProps) => (
    <Menu {...menuProps}>
      {results.map((result, props) => (
        <TypeaheadMenuItem>
          {result.label}
        </TypeaheadMenuItem>
      ))}
    </Menu>
  )}
/>

tokenContainer

Encapsulates keystroke and outside click behaviors used in Token. Useful if you want completely custom markup for the token.

const MyCustomToken = tokenContainer(props => (
  // Your token code...
));

<Typeahead
  multiple
  options={options}
  renderToken={(selectedItem, onRemove) => (
    <MyCustomToken onRemove={onRemove} option={selectedItem} />
  )}
/>
