Oh my God, twitter bootstrap is a pretty damn good styling and widget framework. Check it out!
My first issue with it however is that I couldn't find a way to change the tooltip label after it's been created.
It's easily solved, but with a rather convoluted and hidden method.
1.
$(
'#target'
).attr(
'data-original-title'
, item.value +
' selected.'
).tooltip(
'fixTitle'
);
What this one line wonder does is change the title attribute, then tell it to update using the "fixTitle" call.
