Hello,
Thank you for reaching out to us.
1/ Kindly try disabling the sticky header and check if the issue persists. Alternatively, you may use the following custom CSS code:
.menu-static-block.nav-sublist-dropdown {
max-height: 400px; /* Adjust height as needed */
overflow-y: auto;
}
2/ Theme Options > Speed optimization > Ajax menu dropdown > off.
