      { value: "vanilla", label: "Vanilla" },
      { value: "strawberry", label: "Strawberry" },
    ],
  };

  handleSelection = (selectedItems) => {
    this.setState({ selectedItems });
  };

  handlePageRequested = async (filter, page, pageSize) => {
    try {
      this.setState({ loading: true });

      const newItems = await // GET ITEMS

      this.setState({
        items: [
          ...(page > 0 ? items : []),
          ...newItems.slice(page * pageSize, (page + 1) * pageSize),
        ],
      });

        pageSize={15}
        onPage={this.handlePageRequested}

With React Hooks

import React, { useState } from "react";
import Select from "select";

const options = [
  { value: "chocolate", label: "Chocolate" },
  { value: "strawberry", label: "Strawberry" },
  { value: "vanilla", label: "Vanilla" },
  { value: "blueberry", label: "Blueberry" },
];

const App = () => {
  const [loading, setLoading] = useState(false);
  const [items, setItems] = useState([]);
  const [selectedItems, setSelectedItems] = useState([
    { value: "vanilla", label: "Vanilla" },
    { value: "strawberry", label: "Strawberry" },
  ]);

  const handlePageRequested = async (filter, page, pageSize) => {
    try {
      setLoading(true);

      const newItems = await // GET ITEMS

      setItems([
        ...(page > 0 ? items : []),
        ...newItems.slice(page * pageSize, (page + 1) * pageSize),
      ]);
    } finally {
      setLoading(false);
    }
  };

  return (
    <Select

      items={items}
      placeholder="Placeholder text"
      outlined
      loading={loading}
      selected={selectedItems}
      onSelection={setSelectedItems}
      pageSize={15}
      onPage={handlePageRequested}

export default App;

Props

Common props you may want to specify include:

• multiple - allow the user to select multiple values
• items - specify the options the user can select from
• placeholder - change the text displayed when no option is selected
• outlined - specify if the select component is supposed to look outlined
• loading - specify if the component should be in a loading state
• selected - control the current value selected
• onSelection - subscribe to change event
• onPage - subscribe to requesting new page of options event
• pageSize - specify the number of options the component will request when

Items

Option items passed to the component need to be of type:

{ value: string, label: string }

onPage

onPage property points to the callback function that will be called whenever component requests new page

handlePageRequested: (filter: (string | null), page: number, pageSize: number) => Promise<void>

where:

• filter: (string | null)
  • a string that represents user input at the moment of requesting a new page. Value can be and will be null the first time component requests new data and as long as user did not type anything. After typing and emptying the input, value is an empty string.
• page: number:
  • index of the new page to paginate the data for.
• pageSize: number:
  • size of the page
