How do I remove the overlay menu on my website, ive tried everything but haven't seen the options. Can I get some help with this many thanks. 

You mean

• remove burger overlay menu on mobile
• force desktop menu appear on mobile

Is this right?

I changed mine to the plus sign but yes thats correct.

Add to Design > Custom CSS

/* Force desktop nav on tablet mobile - version 2 */
@media screen and (max-width:991px) {
.header-display-desktop {
    display: flex !important;
}
.header-display-mobile {
    display: none;
}
.header-burger {
    display: none;
}
.header-nav {
    display: flex !important;
}
.header-nav {
    display: flex !important;
    flex: 70% !important;
    justify-content: flex-end;
    width: 70% !important;
}
.header-title {
    flex: 50% !important;
}
.showOnDesktop .header-actions-action.header-actions-action--cart {
    display: none;
}
}

Which buttons are you referring to? Or You mean space between nav links?

Yes the space between the nav links or atleast an area in the custom code that I can use to adjust it?

Try this new code

/* Force desktop nav on tablet mobile - version 2 */
@media screen and (max-width:991px) {
.header-display-desktop {
    display: flex !important;
}
.header-display-mobile {
    display: none;
}
.header-burger {
    display: none;
}
.header-nav {
    display: flex !important;
}
.header-nav {
    display: flex !important;
    flex: 70% !important;
    justify-content: flex-end;
    width: 70% !important;
}
.header-title {
    flex: 50% !important;
}
.showOnDesktop .header-actions-action.header-actions-action--cart {
    display: none;
}
    .header-nav-item {
        margin-left: 3.5vw !Important;
    }
}

Much better thank you so much for your help!
