Text Fields Similar to Treepad This file provides a single long text field for each node. This is similar to how the Treepad program on windows is usually used. Plain text field Text fields can be set to plain text, so all line breaks and other white space are preserved. You can also use characters like <, > and & without escaping them. HTML text field An HTML field allows tags like <i>itallics</> to be used. It does not preserve white space. Characters like &lt;, &gt;, and &amp; must be escaped.
