Hello David.
Thank you very much. I add now the code.
However, the problem could not be solved completely.
When the search button is pressed, there is no longer a shift and that’s good.
However, both the navigation and the search button are below the logo under a new line, which is not intended.
All elements, i.e. logo, navigation and search button should be on the same line.
How could the problem be solved?
PS: Do you know how I can upload an avatar in this forum for me?
