I tried to follow this help: Search in the Top menü
But there are too many options and advices, I got lost, It is hard to follow the procedure. Even that I tried and seems that nothing works for me. Probably I do some mistake somewhere.
I would like to have an expandable search box at the top of my site next to: Chci na degustaci!
Similar as it is on this page: https://birddoglogic.com/
My website is : https://rumme.cz
I know it may be a long and hard way to resolve this problem. On the other hand, the search box is something the site is really missing.
Thank you in advance.
