I am really sorry about the loss of time you had and I hope this information will be of help to you.
1) Vertical menu uses RadTabStrip
control to display the menu. To achieve right flyout you could either do it with separating your page template layout ( if it`s ok with you ) or create a custom navigation that uses RadTabstrip control with the property you require like described here
2) I hope this
forum topic will help you with your Stylebuilder troubles.
3) Styling Sitefinity navigation with your skin might provide some conflicts with your css and the css of the Sitefinity current theme as you have shown in your screenshot ( some properties get overwritten ). To avoid this I suggest using your own theme or just blank theme.
4) We apologize for the inconvenience this causes you, but currently RadTabStrip uses tabs. If you need to use menu`s consider some other control like RadTreeView if it suits your expectations.
5) Does the attached screenshot (page_group.png) describes the situation you are talking about. Please provide me with more information on this problem.
I hope this information was helpful and feel free to write back if you got any more problems.
All the best,
the Telerik team
