Expected behaviour

when rendering a quiz with a select-box like this:

- `(13 % 3) * 2` ergibt [[0|1|(2)|4]] und ist vom Typ [[(int)|float]]

I expect that opening the drop down menu does not push the layout downwards.

Observed behaviour

opening the drop-down pushes the layout down.

Suggested Fix

drop-down menus should have position: fixed so they dont cause the layout to re-flow around the now open list of options.

Making the background of the drop-down opaque would be required as well.
