You can use the tree views successfully if an event on the branch generates the lower branch. We use this for drilling in active data and it works very nicely. A static treeview isn't nearly as powerful of course and that is an issue when using, for example, behaviors in pages. Len http://www.mp3.com/LenBullard Ekam sat.h, Vipraah bahudhaa vadanti. Daamyata. Datta. Dayadhvam.h -----Original Message----- From: Rick Jelliffe [mailto:ricko@a...] The popularity of the tree-based interface to XML editing is perplexing, given that tree views are quite cumbersome to use for documents with more than a handful of elements at any significant level. For "data" documents, the order is usually not so important, so being able to move branches around is not important; for prose documents, you normally cannot see enough of the data content to make much use. I suspect it is just that Java/VB/C++ have convenient widgets for tree-views, so programmers think "oh that is good". If the desire is to allow some kind of outlining, but that is to little avail if other word processing features are missing. And, there is a good proportion of the world which still uses 15" monitors or notebooks: they just cannot spare the screen real estate for any clutter.
