I need to move to 7.1 templates but there isn't a left justified menu template that I can see, can I change it in 7.1 templates?

I see 7.0 templates that have left justified menus, but I don't see that option for 7.1. Seems VERY BASIC, so am sure I am missing something. 

How can move the menu to the left hand side in 7.1? Many thanks!

You are not missing anything.

I don't know of a solution to the effect you want to achieve. However it may be possible to achieve it. Here is an experiment with CSS only.

#siteWrapper {

  display : grid;
  grid-template-areas : "header header"
                        "left main"
                        "footer footer";
  grid-template-columns : 20vw 80vw;
  
  }

.floating-cart {

  grid-area : header;
  
  }

#header {

  grid-area : left;
  position : unset;
  
  }

#page {

  grid-area : main;
  
  }

#footer-sections {

  grid-area : footer;
  
  }

#page .page-section:first-child {

  padding-top : unset !important;
  
  }

.header-display-desktop,
.header-title-nav-wrapper,
.header-nav-list

  {
  
    flex-direction : column;
    
    }

.header-title-nav-wrapper {

  align-items : unset;
  
  }

.header-layout-nav-right .header-nav-list {

  justify-content : unset;
  
  }

.header-layout-nav-right .header-nav {

  text-align : left;
  
  }

.header-layout-nav-right .header-nav,
.header-layout-nav-right .header-nav-item:not( :first-child ):not( .header-actions-action--cart ) {

  margin-left : unset;
  
  }

.header-layout-nav-right .header-nav {

  padding-left : unset;
  
  }

Again this is not a solution it is an experiment. I did not exhaustively test all the elements of the page to see if they would fit or work properly. Also one would probably want to restrict this effect to desktop only.

What this code shows is that it may be possible to achieve the effect you want with some not insignificant amount of work.

Thank You Creedon! Very helpful I will try this out. 

I did find this as part of the Jotterpress template. Which does 75% of what I want. It does not have an accordian effect with categories then sub pages like on my 7.0 site. 

Cheers, Will get back to you.
