useMultiToggle

This is a hook to manage multiple boolean states. For example, showing multiple checkboxes or keeping track of whether multiple dropdowns are open.

Usage

Initial state defaults to an empty array. If you are using typescript you can specify the type of item:

import { useMultiToggle } from "react-use-multi-toggle";

const YourComponent = () => {
  const actions = useMultiToggle<number>([1, 2, 3]);
};

Here is how some of the actions can be used:

import { useMultiToggle } from "react-use-multi-toggle";

const YourComponent = () => {
  const { toggle, add, remove, has } = useMultiToggle([1, 2, 3]);

  return (
    <div>
      {has(1) && <p>1</p>}
      {has(2) && <p>2</p>}
      {has(100) && <p>100</p>}
      <button onClick={() => actions.toggle(1)}>Toggle 1</button>
      <button onClick={() => actions.add(100)}>Add 100</button>
      <button onClick={() => actions.remove(2)}>Remove 2</button>
    </div>
  );
};

Reference

const {
  toggle,
  add,
  remove,
  has,
  hasSome,
  hasAll,
  set,
  values,
} = useMultiToggle();

• add<T>(T | T[]): void - adds one or many elements;
• remove<T>(T | T[]): void - removes one or many elements;
• toggle<T>(T): void - inverts state of element: either adds or removes it;
• set<T>(T[]): void - directly calls useState setter;
• has<T>(T): void - indicates element is in state;
• hasSome<T>(T[]): void - indicates some elements are in state;
• hasAll<T>(T[]): void - indicates all elements are in state;
• values: T[] - all elements in state;
