# clearBlockTypes

To remove the whole applied block types such as headings or lists from the current
selection you can use the `clearBlockTypes` function.

## Usage

The `clearBlockTypes` utility will clear the block types from your selection. It'll
automatically remove your custom block types as well.

```ts
clearBlockTypes(
  state: State,
  stateHandler: StateHandler,
) => State
```

## Example

An example of `clearBlockTypes` usage:

```ts
import { useState } from 'react';
import { EditorState } from 'draft-js';
import { Editor, clearBlockTypes, toggleH1, isH1 } from 'contenido';


const Demo = () => {
  const [editorState, setEditorState] = useState(
    EditorState.createEmpty()
  );

  return (
    <>
      <Editor
        editorState={editorState}
        onChange={setEditorState}
        editorRef={editorRef}
      >
      <button
        onMouseDown={(e) => {
          e.preventDefault();
          toggleH1(editorState, setEditorState)
        }}
        style={{color: isH1(editorState) ? 'skyblue' : 'black'}}
      >
        Bold
      </button>
      <button
        onMouseDown={(e) => {
          e.preventDefault();

          clearBlockTypes(editorState, setEditorState)
        }}
      >
        Clear BlockTypes
      </button>
    </>
  )
}

export default Demo;
```
