useCheckboxGroup

Introduction

The useCheckboxGroup hook is a custom React hook that manages the state of a group of checkboxes and provides toggle functionality.

Why useCheckboxGroup?

Managing the state of a group of checkboxes in React can be tedious, especially when it comes to handling toggling the checked state of all checkboxes or individual checkboxes. This hook provides a simple and efficient way of handling the state of a group of checkboxes in React.

Parameters

initialCheckedState: An optional initial value for the checked state of the checkboxes. The default value is an empty array.

Return Value

An object containing the following properties and functions:

checkedItems: An array containing the checked state of the checkboxes.
setCheckedItems: A function to update the state of the checkboxes.
isIndeterminate: A boolean indicating whether the checked state of some, but not all, checkboxes is true.
isAllChecked: A boolean indicating whether the checked state of all checkboxes is true.
handleToggleAll: A function to handle toggling the checked state of all checkboxes.
handleToggleItem: A function to handle toggling the checked state of an individual checkbox.

Installation

To install useCheckboxGroup using npm, run the following command:

npm install @pillar-ui/hooks
yarn add @pillar-ui/hooks

Usage

To use useCheckboxGroup in a React component, import it as follows:

import { useCheckboxGroup } from '@pillar-ui/hooks'

const { checkedItems, setCheckedItems, isIndeterminate, isAllChecked, handleToggleAll, handleToggleItem } =
  useCheckboxGroup()

use Case

Creating a list of checkboxes for user selection: You can use the hook to manage the state of a group of checkboxes in a list or table, and update the state when the user selects or deselects checkboxes.
Creating a checkbox to toggle the selection of all other checkboxes: You can use the hook to manage the state of a group of checkboxes and implement a "select all" checkbox that toggles the checked state of all other checkboxes in the group.
Implementing a filter system: You can use the hook to manage the state of a group of checkboxes that represent filters for a data set. When the user selects one or more checkboxes, the data is filtered accordingly.
Implementing a tag system: You can use the hook to manage the state of a group of checkboxes that represent tags for a content item. When the user selects one or more checkboxes, the tags are added to the content item.
Creating a multi-select dropdown: You can use the hook to manage the state of a group of checkboxes and implement a dropdown that allows the user to select multiple options. The selected options are displayed as tags, and the state is updated as the user selects or deselects checkboxes.-**
