Wrap selected text in a blockquote element to visually distinguish quotations, excerpts, and callouts from the surrounding content. Blockquotes can be nested for multi-level citations.

<richtextbox
    name="blockquoteEditor"
    toolbar="{insertblockquote,indent,outdent}|{bold,italic}|{undo,redo}"
    height="300px"
    html="..." />
