To-do lists

The to-do list feature lets you create a list of interactive checkboxes with labels. It supports all features of regular lists so you can nest a to-do list together with bulleted and numbered lists in any combination.

To-do lists can be introduced using the dedicated toolbar button. Thanks to the integration with the autoformatting feature, they can also be added with Markdown code. Simply start a line with [ ] or [x] followed by a space to insert an unchecked or checked list item, respectively.

After reading this guide, you may find additional interesting details and examples in the Lists in CKEditor 5 blog post.

# Demo

Use the Insert to-do list toolbar button to add a list to the editor content.

# Keyboard support

You can check and uncheck a list item by using the Ctrl + Enter (Cmd + Enter on Mac) shortcut when the selection is in that item.

# Installation

To add this feature to your editor, install the @ckeditor/ckeditor5-list package:

npm install --save @ckeditor/ckeditor5-list

Then add the TodoList plugin to your plugin list and the toolbar configuration:

import TodoList from '@ckeditor/ckeditor5-list/src/todolist';

ClassicEditor
    .create( document.querySelector( '#editor' ), {
        plugins: [ TodoList, ... ],
        toolbar: [ 'todoList', ... ],
    } )
    .then( ... )
    .catch( ... );

# HTML structure

When you call editor.getData(), a to-do list will be represented as the following HTML:

<ul class="todo-list">
    <li>
        <label class="todo-list__label">
            <input type="checkbox" disabled [checked] />
            <span class="todo-list__label__description">Foo</span>
        </label>
    </li>
</ul>

For nested lists:

<ul class="todo-list">
    <li>
        <label class="todo-list__label">
            <input type="checkbox" disabled [checked] />
            <span class="todo-list__label__description">Foo</span>
        </label>
        <ul class="todo-list">
            <li>
                <label class="todo-list__label">
                    <input type="checkbox" disabled [checked] />
                    <span class="todo-list__label__description">Bar</span>
                </label>
            </li>
        </ul>
    </li>
</ul>

# Model representation

From the technical point of view, to-do lists are built on top of the list feature. In the CKEditor 5 data model they are represented as a special listType, with an optional todoListChecked attribute:

<listItem listType="todo">Foo</listItem>

<listItem listType="todo" todoListChecked="true">Bar</listItem>

# Ordered and unordered lists

You can read more about these features in the lists feature guide.
