Underline

Use this extension to render text underlined. If you pass <u> tags, or text with inline style attributes setting text-decoration: underline in the editor’s initial content, they all will be rendered accordingly.

Be aware that underlined text in the internet usually indicates that it’s a clickable link. Don’t confuse your users with underlined text.

::: warning Restrictions The extension will generate the corresponding <u> HTML tags when reading contents of the Editor instance. All text marked underlined, regardless of the method will be normalized to <u> HTML tags. :::
