Autocomplete input field for React
Demo and playground are available here
import TextInput from 'react-autocomplete-input';
import 'react-autocomplete-input/dist/bundle.css';
<TextInput options={["apple", "apricot", "banana", "carrot"]} />
import TextInput from 'react-autocomplete-input';
import 'react-autocomplete-input/dist/bundle.css';
<TextInput trigger={["@", "@@"]} options={{"@": ["aa", "ab", "abc", "abcd"], "@@": ["az", "ar"]}} />
Here for trigger @
first set of options will resolve and for @@
โ second set.
- Supports both keyboard and mouse for option selection
- Supports responsiveness and works on every device
- Supports lazy-loading and dynamic option list updates
- Supports all major browsers including IE 8+
Note: All props are optional.
Widget for rendering input field
Initial text for input
Disables widget, i.e. during form submission
Defines how many options can be listed simultaneously. Show all matched options if maxOptions equals 0.
Callback invoked upon selecting an option. Receives selection value as a parameter.
Callback invoked upon selecting an option, will display what the function returns. Receives trigger and selection value as a parameter.
Callback for requesting new options to support lazy-loading. If requestOnlyIfNoOptions
is true, then onRequestOptions
called only if no options are currently available. Otherwise onRequestOptions
is called every time text is changed and trigger
is found.
import React from 'react';
import TextInput from 'react-autocomplete-input';
class MyComponent extends React.Component {
constructor(props) {
super(props);
this.handleRequestOptions = this.handleRequestOptions.bind(this);
this.state = { options: ["apple", "apricot", "banana", "carror"] };
}
// text in input is "I want @ap"
handleRequestOptions(part) {
console.log(part); // -> "ap", which is part after trigger "@"
this.setState({ options: SOME_NEW_OPTION_ARRAY });
}
render() {
return <TextInput onRequestOptions={this.handleRequestOptions} options={this.state.options} />;
}
}
If true, will match options in the middle of the word as well

List of available options for autocomplete
This regular expression checks if text after trigger
can be autocompleted or not. I.e. "@ap" matches the default regex as "ap" matches the regex, therefore library will try to find appropriate option. "@a$p" fails to match the regex as there is not "$" character in it, therefore library considering this string as irrelevant.
If requestOnlyIfNoOptions
is true, then onRequestOptions
called only if no options are currently available. Otherwise onRequestOptions
is called every time text is changed and trigger
is found.
By default, after option is selected, it is inserted with following spacer
. If user inputs one of the characters from spaceRemovers
array, then spacer
is automatically removed. I.e. @apple ,|
is automatically changed to @apple, |
, where |
represents caret.
Character which is inserted along with the selected option.
Character or string, which triggers showing autocompletion option list. '' and '@@' are both valid triggers. Keep in mind that user have to input at least one extra character to make option list available if empty trigger is used.
Only show autocompletion option list after this many characters have been typed after the trigger character.
Widget supports both controlling options: by value and by state. If you explicitly pass value
prop, you have to update it manually every time onChange
event is emitted. If you don't pass value
prop, then widget uses internal state for value manipulation.
If true, then an enter / return keypress is passed on (after being used to autocomplete). Useful if you want to have the form submit as soon as a single value is chosen.
If true, then an Tab keypress is passed on (after being used to autocomplete) to the next form input. Else, it allows users to autocomplete their input with tab and keep typing.
By default styles are defined in "react-autocomplete-input/dist/bundle.css"
, however, you may define your custom styles instead for following entities:
ul.react-autocomplete-input
ul.react-autocomplete-input > li
ul.react-autocomplete-input > li.active
- Native "Undo" action is not fully supported. It might be changed in the future but currently there is no out-of-the-box solution, which solves this issue for all browsers at once.
- It is considered that list of options will be always small, lets say up to 2000 items. Therefore, options are stored internally as array. If your use-case requires to work with huge lists, I would recommend to reimplement option internal representation as binary search tree instead.
