About Visual Tools Markup Language (VTML)
You can change the content and layout of tag editors by editing VTML files directly in
HomeSite+ for Dreamweaver MX.
You can also create your own editors. Many custom tag developers use VTML to build
tag editors to distribute with their tags libraries. You can find a selection of custom
dialogs and tag editors in the VTML section of the Visual Tools Developer Exchange
at http://devex.macromedia.com/developer/gallery/VisualTools.cfm.
VTML controls and customizes the following user interface elements:
• Tag Inspector
• Tag Tips (F2 in a tag)
• Tag Insight
• Tag Editing Dialogs
• Tag Outline Profiles
• Wizards
• Tag Chooser elements
• Expression Builder
