Devexpress Form With Header Panel (Title) and Menu Below Panel

Can someone give me insight how can I achieve the form with panel title first and then menu bar below panel (barmanager). Because devexpress always put barmanager on top
Thank you
EDIT :
After I add standalonebardock, the result as picture shown below: the red bar is standalonebardock
UPDATE :
After I drag the barmanager menu into standalonedock, now it is already inside the dock. But the menu still on top docking, what I need how to make space above menu so I can write title/image/etc
The StandaloneBarDockControl control allows bars to be displayed at any position within the form, not simply docked to the form’s edge. To do this, create a StandaloneBarDockControl object and add bars to it. Bars can be added to the control at design time or runtime.

You have the following options to do a vertical scroll view:
Ti.UI.ScrollView
Ti.UI.ListView
Ti.UI.TableView
The second one is the most performant and there are several widgets to help you with adding more images as the user scrolls down.

What scrolling / list control is used on Windows 10 store?

I'm playing around with Windows Universal App development. When looking at the Windows 10 Store App, I noticed a scrolling list control as shown in the below screenshot. Clicking the right arrow will shift right by a certain number of elements. Likewise on the other side, clicking the left arrow will shift back.
Is the scrolling control in the Store App a standard control or something custom made?
I'm aware of things like the ScrollViewer, but that just adds a scroll bar.
I created this by the following:
Grid with 3 columns with widths 3*, 94*, 3*
First column contains Button stretched vertically and horizontally to fill the grid and a ListView
Second column contains nothing
Third column contains Button stretched vertically and horizontally to fill the grid and a ListView
Button clicks fire events to calculate how many places to scroll left or right and then uses ListView.ScrollIntoView to scroll the items into view
