RichTextEditor

This module allows to customize the built-in toolbar of the Rich Text Editor and use commands from the HTML Editing APIs. It's highly recommended to keep this toolbar as small as possible, especially from styling commands (eg. 'fontSize') and leave this task to the Style Manager

You can customize the initial state of the module from the editor initialization, by passing the following Configuration Object

const editor = grapesjs.init({
 richTextEditor: {
   // options
 }
})

Once the editor is instantiated you can use its API. Before using these methods you should get the module from the instance

const rte = editor.RichTextEditor;

Examples

rte.add('bold', {

  result: rte => rte.exec('bold')
});
rte.add('link', {
  icon: document.getElementById('t'),
  attributes: {title: 'Link',}

        <option>1</option>
        <option>4</option>
        <option>7</option>
      </select>`,
    // Bind the 'result' on 'change' listener
  event: 'change',
  result: (rte, action) => rte.exec('fontSize', action.btn.firstChild.value),
  // Callback on any input change (mousedown, keydown, etc..)
  update: (rte, action) => {
    const value = rte.doc.queryCommandValue(action.name);
    if (value != 'false') { // value is a string
      action.btn.firstChild.value = value;
    }
   }
  })
// An example with state
const isValidAnchor = (rte) => {
  // a utility function to help determine if the selected is a valid anchor node
  const anchor = rte.selection().anchorNode;
  const parentNode  = anchor && anchor.parentNode;
  const nextSibling = anchor && anchor.nextSibling;
  return (parentNode && parentNode.nodeName == 'A') || (nextSibling && nextSibling.nodeName == 'A')
}
rte.add('toggleAnchor', {
  icon: `<span style="transform:rotate(45deg)">&supdsub;</span>`,
  state: (rte, doc) => {
   if (rte && rte.selection()) {
     // `btnState` is a integer, -1 for disabled, 0 for inactive, 1 for active

   } else {
     return btnState.INACTIVE;
