# Comments

# Overview

This feature makes it possible to add, edit and remove comments in Handsontable easily.

# Enabling the plugin

Set the comments property to true to enable the feature and add all the needed context menu items. For example:

const hot = new Handsontable(container, {
  data: Handsontable.helper.createSpreadsheetData(10, 10),
  comments: true

# Adding the comments via the Context Menu

After you've enabled the plugin, the Context Menu gains a few new items:

  • Add/Edit comment
  • Delete comment
  • Read-only comment

# Setting up pre-set comments

You can also pre-define comments for your table. Comments are stored in the table's/column's/cell's metadata object and can be declared as any value of that type. For example:

cell: [
  { row: 1, col: 1, comment: { value: 'Hello world!' } }

In this example, the comment "Hello world!" is added to the cell at (1,1).

# Basic example

    # Make a comment read-only

    By default, all comments are editable. To change this, set the readOnly parameter to true when adding a comment. This example makes the "Tesla" comment attached to a cell read-only, whereas the "Honda" comment attached to another cell is editable.

      # Set a comment box's size

      To set the width and height of a comment box, use the style parameter.

        # Set a delay for displaying comments

        To display comments after a pre-configured time delay, use the displayDelay parameter.
