# Comments

# Description

This plugin allows setting and managing cell comments by either an option in the context menu or with the use of the API.

To enable the plugin, you'll need to set the comments property of the config object to true:

comments: true

or an object with extra predefined plugin config:

comments: {
  displayDelay: 1000,
  readOnly: true,
  style: {
    width: 300,
    height: 100
  }
}

To add comments at the table initialization, define the comment property in the cell config array as in an example below.

Example

const hot = new Handsontable(document.getElementById('example'), {
  data: getData(),
  comments: true,
  cell: [
    {row: 1, col: 1, comment: {value: 'Foo'}},
    {row: 2, col: 2, comment: {value: 'Bar'}}
  ]
});

// Access to the Comments plugin instance:
const commentsPlugin = hot.getPlugin('comments');

// Manage comments programmatically:
commentsPlugin.setCommentAtCell(1, 6, 'Comment contents');
commentsPlugin.showAtCell(1, 6);
commentsPlugin.removeCommentAtCell(1, 6);

// You can also set range once and use proper methods:
commentsPlugin.setRange({from: {row: 1, col: 6}});
commentsPlugin.setComment('Comment contents');
commentsPlugin.show();
commentsPlugin.removeComment();
