BoxManager 
The BoxManager interface manages a collection of BoxComponent objects. It allows you to add, remove, and retrieve the names of components.
Note
The constructor is not directly accessible. Instead, you can access its methods via the Editor.box object.
Example:
import { query, Editor } from 'lakelib';
const hrBox = {
  type: 'block',
  name: 'hr',
  render: box => {
    const editor = box.getEditor();
    const boxContainer = box.getContainer();
    const rootNode = query('<div class="lake-hr"><hr /></div>');
    boxContainer.empty();
    boxContainer.append(rootNode);
    rootNode.on('click', () => {
      editor.selection.selectBox(box);
    });
  },
  html: () => '<hr />',
};
