Usage

Basic Usage

import { Flex, FormControl, FormHelperText, FormLabel } from "@chakra-ui/react";
import * as React from "react";
import {
  AutoComplete,
  AutoCompleteInput,
  AutoCompleteItem,
  AutoCompleteList,
} from "@choc-ui/chakra-autocomplete";

function App() {
  const countries = [
    "nigeria",
    "japan",
    "india",
    "united states",
    "south korea",
  ];

  return (
    <Flex pt="48" justify="center" align="center" w="full">
      <FormControl w="60">

          <AutoCompleteInput variant="filled" />
          <AutoCompleteList>
            {countries.map((country, cid) => (
              <AutoCompleteItem
                key={`option-${cid}`}
                value={country}
                textTransform="capitalize"
              >
                {country}
              </AutoCompleteItem>
            ))}
          </AutoCompleteList>
        </AutoComplete>
        <FormHelperText>Who do you support.</FormHelperText>
      </FormControl>
    </Flex>
  );
}

export default App;

Creating Groups

You can create groups with the AutoCompleteGroup Component, and add a title with the AutoCompleteGroupTitle component.

import { Flex, FormControl, FormHelperText, FormLabel } from "@chakra-ui/react";
import * as React from "react";
import {
  AutoComplete,
  AutoCompleteGroup,
  AutoCompleteGroupTitle,
  AutoCompleteInput,
  AutoCompleteItem,
  AutoCompleteList,
} from "@choc-ui/chakra-autocomplete";

function App() {
  const continents = {
    africa: ["nigeria", "south africa"],
    asia: ["japan", "south korea"],
    europe: ["united kingdom", "russia"],
  };

  return (
    <Flex pt="48" justify="center" align="center" w="full">
      <FormControl w="60">
        <FormLabel>Olympics Soccer Winner</FormLabel>
        <AutoComplete openOnFocus>
          <AutoCompleteInput variant="filled" />
          <AutoCompleteList>
            {Object.entries(continents).map(([continent, countries], co_id) => (
              <AutoCompleteGroup key={co_id} showDivider>
                <AutoCompleteGroupTitle textTransform="capitalize">
                  {continent}
                </AutoCompleteGroupTitle>
                {countries.map((country, c_id) => (
                  <AutoCompleteItem
                    key={c_id}
                    value={country}
                    textTransform="capitalize"
                  >
                    {country}
                  </AutoCompleteItem>
                ))}
              </AutoCompleteGroup>
            ))}
          </AutoCompleteList>
        </AutoComplete>
        <FormHelperText>Who do you support.</FormHelperText>
      </FormControl>
    </Flex>
  );
}

export default App;

Accessing the internal state

To access the internal state of the AutoComplete, use a function as children (commonly known as a render prop). You'll get access to the internal state isOpen, with the onOpen and onClose methods.

import {
  Flex,
  FormControl,
  FormHelperText,
  FormLabel,
  Icon,
  InputGroup,
  InputRightElement,
} from "@chakra-ui/react";
import * as React from "react";
import {
  AutoComplete,
  AutoCompleteInput,
  AutoCompleteItem,
  AutoCompleteList,
} from "@choc-ui/chakra-autocomplete";
import { FiChevronRight, FiChevronDown } from "react-icons/fi";

function App() {
  const countries = [
    "nigeria",
    "japan",
    "india",
    "united states",
    "south korea",
  ];

  return (
    <Flex pt="48" justify="center" align="center" w="full">
      <FormControl w="60">
        <FormLabel>Olympics Soccer Winner</FormLabel>
        <AutoComplete openOnFocus>
          {({ isOpen }) => (
            <>
              <InputGroup>
                <AutoCompleteInput variant="filled" placeholder="Search..." />
                <InputRightElement
                  children={
                    <Icon as={isOpen ? FiChevronRight : FiChevronDown} />
                  }
                />
              </InputGroup>
              <AutoCompleteList>
                {countries.map((country, cid) => (
                  <AutoCompleteItem
                    key={`option-${cid}`}
                    value={country}
                    textTransform="capitalize"
                  >
                    {country}
                  </AutoCompleteItem>
                ))}
              </AutoCompleteList>
            </>
          )}
        </AutoComplete>
        <FormHelperText>Who do you support.</FormHelperText>
      </FormControl>
    </Flex>
  );
}

export default App;

Custom Rendering

You can Render whatever you want. The AutoComplete Items are regular Chakra Boxes.

import {
  Avatar,
  Flex,
  FormControl,
  FormHelperText,
  FormLabel,
  Text,
} from "@chakra-ui/react";
import * as React from "react";
import {
  AutoComplete,
  AutoCompleteInput,
  AutoCompleteItem,
  AutoCompleteList,
} from "@choc-ui/chakra-autocomplete";

function App() {
  const people = [
    { name: "Dan Abramov", image: "https://bit.ly/dan-abramov" },
    { name: "Kent Dodds", image: "https://bit.ly/kent-c-dodds" },
    { name: "Segun Adebayo", image: "https://bit.ly/sage-adebayo" },
    { name: "Prosper Otemuyiwa", image: "https://bit.ly/prosper-baba" },
    { name: "Ryan Florence", image: "https://bit.ly/ryan-florence" },
  ];

  return (
    <Flex pt="48" justify="center" align="center" w="full" direction="column">
      <FormControl id="email" w="60">
        <FormLabel>Olympics Soccer Winner</FormLabel>
        <AutoComplete openOnFocus>
          <AutoCompleteInput variant="filled" />
          <AutoCompleteList>
            {people.map((person, oid) => (
              <AutoCompleteItem
                key={`option-${oid}`}
                value={person.name}
                textTransform="capitalize"
                align="center"
              >
                <Avatar size="sm" name={person.name} src={person.image} />
                <Text ml="4">{person.name}</Text>
              </AutoCompleteItem>
            ))}
          </AutoCompleteList>
        </AutoComplete>
        <FormHelperText>Who do you support.</FormHelperText>
      </FormControl>
    </Flex>
  );
}

export default App;

Multi Select with Tags

Add the multiple prop to AutoComplete component, the AutoCompleteInput will now expose the tags in it's children function. The onChange prop now returns an array of the chosen values

Now you can map the tags with the AutoCompleteTag component or any other component of your choice. The label and the onRemove method are now exposed.

import { Flex, FormControl, FormHelperText, FormLabel } from "@chakra-ui/react";
import * as React from "react";
import {
  AutoComplete,
  AutoCompleteInput,
  AutoCompleteItem,
  AutoCompleteList,
  AutoCompleteTag,
} from "@choc-ui/chakra-autocomplete";

function App() {
  const countries = [
    "nigeria",
    "japan",
    "india",
    "united states",
    "south korea",
  ];

  return (
    <Flex pt="48" justify="center" align="center" w="full" direction="column">
      <FormControl id="email" w="60">
        <FormLabel>Olympics Soccer Winner</FormLabel>
        <AutoComplete openOnFocus multiple onChange={vals => console.log(vals)}>
          <AutoCompleteInput variant="filled">
            {({ tags }) =>
              tags.map((tag, tid) => (
                <AutoCompleteTag
                  key={tid}
                  label={tag.label}
                  onRemove={tag.onRemove}
                />
              ))
            }
          </AutoCompleteInput>
          <AutoCompleteList>
            {countries.map((country, cid) => (
              <AutoCompleteItem
                key={`option-${cid}`}
                value={country}
                textTransform="capitalize"
                _selected={{ bg: "whiteAlpha.50" }}
                _focus={{ bg: "whiteAlpha.100" }}
              >
                {country}
              </AutoCompleteItem>
            ))}
          </AutoCompleteList>
        </AutoComplete>
        <FormHelperText>Who do you support.</FormHelperText>
      </FormControl>
    </Flex>
  );
}

export default App;

Creatable Items

I know that title hardly expresses the point, but yeah, naming is tough. You might want your users to be able to add extra items when their options are not available in the provided options. e.g. adding a new tag to your Polywork profile.

First add the creatable prop to the AutoComplete component. Then add the AutoCompleteCreatable component to the bottom of the list. Refer to the references for more info on this component.

Loading State

Need to pull data from API, but don't want your users to see a blank screen? You can enable the loading state by passing the isLoading prop to AutoComplete. By doing this, 2 other props will be enabled

1. loadingIcon on AutoCompleteInput will display some sort of loading icon on the right side of the input. By default, a Spinner will be displayed, but you can pass in any custom element to be rendered

2. loadingState on AutoCompleteList can display custom loading content when isLoading is true. All content will be rendered in the center of the list. By default, a Spinner will be displayed, but you can pass in any custom element to be rendered.

Best practice is to combine setTimeout and useEffect to create a debounce effect. This will prevent un-necessary API calls if your user types relatively quickly.

A working code demo can be found here

Integration with Form Libraries

It is relatively easy to integrate with form libaries such as React Hook Form, Formik, and others. Working examples can be found in the demos folder of this repo. See the Contributing section of this doc on how to clone and set it up for testing.

Does your favorite form library not have a working example? Submit a PR to get it added and help others using this library quickly get up and running.

Autocomplete methods

Assign a ref to the AutoComplete component and call the available methods with:

ref.current?.resetItems();
ref.current?.removeItem(itemValue);
