Hi,
... another issue with T4 Page Builder 
Mobile menu for "Wedding" layout is not responsive and doesn't disappear during navigation, it remains displayed.
Even in your demo layout, mobile menu is not displayed at all when you navigate on smartphone.
Can you fix this?
Hi
I'm working with my team to export the demo site, something wrong there with the mobile menu.
We're sorry for this inconvenience and I will keep you posted.
UPDATE:
You can try with custom CSS code to fix the issue on your site:
@media (max-width: 76px)
.t4b-header .header-wrap .navbar-expand-lg {
margin-top: 0px;
}Our team will update the demo site also.
... thanks but I solved the problem with T4 framework offcanvas menu which in my opinion is more adequate and aesthetic...
