4) From what I can see, mega menu is already in front.

One comment, the expanding menu is not aligned any more. Can you please check?

#Top_bar:not(.is-sticky) .menu li ul{

What do I need to do that the submenu will start under the main menu and not under the header?

For a test, I changed the font in the menu, and everything worked correctly.

I have added some top and bottom padding to extend the sidebar height and force scroll to show menu items properly.

4) You can set up animation in the header template by changing the Submenu Animation in the Menu settings.

As 960px is still a laptop view, try to decrease a little padding or font size on that view for your menu element.

Page get's stucked nothing work's. You have to close the browser and open again and then the page loads fast.

For example, on 960px screens the menu appears in two lines, and the logo is cut off as in the initial printout.

Making anchor links (in the menu or not) is simple as creating regular links.

How can I make the Mobile Menu Scrollable?

In the Mega Menu template options, you can set the Mega Menu display position:

Please go to Betheme -> Theme options -> Menu & Action Bar -> Action Bar, and there you can edit it.

On my current website the last two menu items are incorrectly aligned. This causes information to be lost. 

I want to edit the information located above the menu on the Betheme Default theme. I can't seem to find where it is for me to change it. See image attached.

Either activate the One Page option in the Page options or add a scroll class to the menu items.
