Hamburger Menu doesn't display and work

[Martjan]

Hi all,

I have tried a lot of responsive hamburger menu's on my website, but it doesn't work.
It does never show the hamburger-menu and a lot went wrong.
The website is https://www.martjanschot.nl. Does anyone know how I make the menu responsive (I prefer a hamburger menu on mobile)?

Thank you in advance!


Yours Sincerely,

Martjan Schot

I have solved my own problem. In the CSS was written an old code with ul and li. I removed this and now it works.
