    <p>
      Framework7 comes with a touch-friendly Rich Text Editor component. It is based on modern
      "contenteditable" API so it should work everywhere as is.
    </p>
    <p>
      It comes with the basic set of formatting features. But its functionality can be easily
      extended and customized to fit any requirements.

  <BlockTitle>Default Setup</BlockTitle>
  <TextEditor />

  <TextEditor placeholder="Enter text..." />

  <BlockTitle>With Default Value</BlockTitle>
  <TextEditor

      ['bold', 'italic', 'underline', 'strikeThrough'],
      ['orderedList', 'unorderedList'],
    ]}
  />

  <BlockTitle>Custom Button</BlockTitle>
  <BlockHeader>
    It is possible to create custom editor buttons. Here is the custom "hr" button that adds
    horizontal rule:
  </BlockHeader>
  <TextEditor
    placeholder="Enter text..."
    {customButtons}
    buttons={[['bold', 'italic', 'underline', 'strikeThrough'], 'hr']}
  />

    placeholder="Enter text..."
    resizable
    buttons={['bold', 'italic', 'underline', 'strikeThrough']}
  />

  <BlockTitle>Popover Mode</BlockTitle>
  <BlockHeader>
    In this mode, there is no toolbar with buttons, but they appear as popover when you select any
    text in editor.
  </BlockHeader>
  <TextEditor
    placeholder="Enter text..."

    In this mode, toolbar with buttons will appear on top of virtual keyboard when editor is in the
    focus. It is supported only in iOS, Android cordova apps and in Android Chrome. When not
    supported it will fallback to "popover" mode.
  </BlockHeader>
  <TextEditor
    placeholder="Enter text..."
    mode="keyboard-toolbar"
    style="--f7-text-editor-height: 150px"
  />

        buttons: ['bold', 'italic', 'underline', 'strikeThrough'],
