Custom Select list to text component?

Hi @tonypartridge here is an example code to achieve that

// An example with fontSize
rte.add('fontSize', {
  icon: `<select class="gjs-field">
        <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;
    }
   }
  })
