Public Schedule Mobile View: change in page menu

[mariobehling]

The in-page menu has a burger menu that is the same as the top burger menu. It should be different.

Please implement a kind of drop-down button with an icon for each menu item and a down arrow. Take inspiration from GitHub as in below screenshot, e.g. see the button "development". In contrast to Github make the menu into a dropdown menu instead of a pop-up menu.

@mariobehling is this the expected result?

@MeghalBisht The dropdown should get expanded by the icon on the right hand side.

So, if the user is on the page "info", then show info. If the user wants to go to ticket, scroll to Tickets and collapse the menu.
