Dropdowns / Split dropdowns not working correctly when attached to single button
In demo page you've placed dropdowns / split dropdowns example in "Buttons" section, not in "Button groups" section (you even gave example codes of button groups there).
But, when a single button (not button group) is converted into dropdown / split dropdown, dropdown menu is drawn in some strange position (middle of page, aligned to left margin -- see attachment).
I don't know, if this is because there are some bugs in Yii-Bootstrap or because Bootstrap at all doesn't support dropdowns for single buttons and they must be combined into button groups to have dropdowns drawn correctly?
BTW: Checkbox and Radio buttons examples are also presented in "Buttons" section, while AFAIK they can't be done with single button and must be build with button group.
