Hi there!
Sorry fo ryour issue.
Please use the following code in your custom CSS:
.offcanvas {
visibility: visible;
}
.offcanvas-menu .offcanvas-inner .sp-module .sp-module-content > ul {
flex-direction: column;
}
Hope this will solve the issue for you!
Note: Path towards custom CSS(Joomla 4): System>Site Templates Styles> Click on your current default template name then choose Template Options. Then find custom CSS within the custom code.
