Hello, I realize that the hamburger menu stays open after it has been clicked, is this by design?

How can I have it closed automaticaly?

Hi there,
Thanks for reaching out.
Relating to your question here, I’m afraid this is the default implementation. Altering this would entail a bit of custom work of which is beyond the scope of our support. I would recommend services from Envato Studio if would wish to have some customizations on this carried out.

Please let us know if you have any more questions.
Best Regards,

Ok thanks for the answer.
Great theme otherwise.
