# BlockManager

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

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

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

const blockManager = editor.BlockManager;
