Usage

Add a new Tool to the tools property of the Editor.js initial config.

var editor = EditorJS({
  ...

  tools: {
    ...
    header: Header,
  },

  ...
});

Available characters: all Latin letters, digitals, dash, and underscore.

In the cyrToLat branch, you can find additional functionality: Cyrillic characters are replaced by Latin letters, for example, ш to sch.

In the maxLength branch, you can find additional functionality: If you want to set the maximum length of the header text, you need to set the checkHeaderLength parameter to TRUE in the config.

In the cyrToLat_with_maxLength branch, you can find additional features from branches cyrToLat and maxLength at the same time.

P.S. The anchor value is displayed next to the header block only when there is text in the header block.

Shortcut

You can insert this Block by a useful shortcut. Set it up with the tools[].shortcut property of the Editor's initial config.

var editor = EditorJS({
  ...

  tools: {
    ...
    header: {
      class: Header,
      shortcut: 'CMD+SHIFT+H',
    },
  },

  ...
});
