You may also want to consider the WindowShade component from FlexLib, instead of the ComboBox: http://flexlib.googlecode.com/svn/trunk/examples/WindowShade/WindowShade_Sample.swf
I found the kmossman example a little confusing to navigate, since clicking on some things selected them (and collapsed the combobox), and clicking others expanded the tree. I understand the intent of the navigation, but it feels a little off. The windowshade may be a slicker way to accomplish the same requirements you stated originally. -- Maciek Sakrejda Truviso, Inc. http://www.truviso.com -----Original Message----- From: Brad Bueche <[EMAIL PROTECTED]> Reply-To: flexcoders@yahoogroups.com To: flexcoders@yahoogroups.com Subject: RE: [flexcoders] Be the tree, Bob Date: Tue, 26 Feb 2008 14:33:26 -0500 Thanks for the feedback Peter and Alex! I have also found these two possible solutions: http://cyberdust.wordpress.com/2007/02/23/introducing-selecttree-the-drop-down-tree-control/#comment-4946 However, this guy did part of it with cf and I'm getting an 1180 Error "Call to possibly undefined method SubjectGateway". I've asked if he can give a flex only example. As I'm a newbie, I'm much more into re-use at this stage than writing the specifics myself (I"m learning as fast as I can!). There is also this solution: http://kmossman.blogspot.com/2007/03/blog-post.html I'm still taking a look at this one. Its a good sign though that you can think of something you might like in flex, google it, and get multiple samples. This is what enabled me to learn php so fast. I found them both by just typing "dropDownFactory = Tree" into Google. brad keywords: Tree Combobox dropDownFactory -----Original Message----- From: flexcoders@yahoogroups.com [mailto:[EMAIL PROTECTED] On Behalf Of Peter DeHaan Sent: Tuesday, February 26, 2008 2:04 PM To: flexcoders@yahoogroups.com Subject: RE: [flexcoders] Be the tree, Bob You could also try something like this: <mx:PopUpButton label="Please select a team..." width="{tree.width}"> <mx:popUp> <mx:Tree id="tree" dataProvider="{mlb}" labelField="@label" showRoot="false" width="300" rowCount="8" /> </mx:popUp> </mx:PopUpButton> And then tweak it slightly to fit your needs.

I really like the idea of having a hierarchical menu that looks exactly like the tree in this example. I just want it to drop down and be a menu like the combo box. I detest the windows file manager interface (because of its inefficient use of screen real-estate) and I dont like cascading menu's because I get really annoyed having to slow down and use my mouse in slow motion just so I can get to the sub-menu I want. I think the drop down tree hiearchy within a combobox solves both of these problems. 1). Its a great use of screen real-estate --- if you are not using it it takes up practically no room and 2) the hierarchy is persistent and I dont have to be a jedi master with my mouse....and I dont have to move %80 down and to the right to get the menu I want. So would it be possible to do a tree in a combo box? Or, if thats impossible, I guess I can just put the tree on a application bar and use it like a menu? brad
