How to Customize the side bar.
i want do something like that too.
did you take care your thing?
Using jQuery to manipulate DOM lets you change many things on UI. Depending of the scope and the behavior expected, try it into client scripts or overriding .js files.
This sample changes the background color of the entire sidebar.
Hope this helps.
i just wanna find if there an official way to complete that.
and now, i think your way is the best.
