Currently, ExtJS 3.1.1 doesn’t support Vertical TabPanel. Here is my simple custom Vertical TabPanel ux class. Currently, it supports the same set of features as Ext.Tabpanel except advanced auto tab-scrolling feature. Default position is “left”.
Tested working on FF2+, IE6+, Chrome 4, Safari 4, and Opera 10.
You can put the source files in ExtJS Tabs folder to test: ext-3.1.1examplestabs..
