Menu on the left

Hi there,

we have a similar layout in our site library:

https://gpsites.co/sider/

However to do that for a pre-built site would require custom development.

Ok so its hard then? There is no way to have the menu on the left?

Are you using GP 3.0+ with the Flex option?

If so you can try this CSS that is used in Sider:

@media (min-width: 1000px) {
	body {
		padding: 0 50px 50px;
		margin-left: 300px;
	}

	.site-header {
		position: fixed;
		left: 0;
		top: 0;
		width: 300px;
		z-index: 300;
		height: 100%;
		overflow: auto;
		overflow-x: hidden;
		-webkit-backface-visibility: hidden;
		-webkit-overflow-scrolling: touch;
		transition: .1s ease;
	}
	
	.admin-bar .site-header {
		top: 32px;
	}
	
	.site-header .main-navigation li {
		float: none;
	}
}

.inside-header {
  flex: 1;
  flex-direction: column;
}

.header-widget {
	order: 3;
	text-align: center;
}

.nav-float-right .inside-header .main-navigation {
	order: 2;
	margin-top: 50px;
	margin-bottom: 50px;
}

.dropdown-click .site-header .main-navigation ul ul {
    position: relative;
}

.main-navigation .main-nav>ul {
    flex-direction: column;
}

.nav-float-right .header-widget {
    margin-left: 0;
}

.nav-float-right .header-widget .widget {
    margin-bottom: 50px;
}

.nav-float-right #site-navigation {
    margin-right: auto;
}
