Hello
I am using “Layla_J4” and am having a problem with the menu. It is covered by the module in “showcase-1a” (image “without_css”). After inserting the CSS, it is displayed correctly (image css), but then there is a problem with the display on mobile devices (menu is not complete). My CSS is:

/* menue im Vordergrund */
.mod-menu {
flex-direction: column;
/* z-index: 1000; */
}
ol, ul {
line-height: 1.5;
margin-top: 0;
z-index: 1000;
}
ol, ul, dl {
margin-top: 0;
margin-bottom: 1rem;
}
ol, ul {
padding-left: 2rem;
}
*, *::before, *::after {
box-sizing: border-box;
z-index: 1;
}

Please help.
Thanks and best regards.
Peter
