Hello @QBC
Could you please define your query?
There is already a header navigation menu on the left side.
I want the menu to be on the left side of the page.
Hi,
Perhaps you mean that you want the menu on the right side? As @oscprofessional specified, your menu is already on the left side and is not very clear what you are trying to achieve.
Cheers!
Hi @QBC , this is not easy task and we might need to get some support from an expert guy. These screenshots below will explain my solution, you could try it and let us know how it goes:
Step 1:
Step 2:
Step 3:
Step 4:
Step 5:
These steps above only help to bring the main menu to the left hand side, but to we will need to edit some other CSS code to fix the other effect like: cart drawer animation or some others effects. We should hire an Shopify expert to help you solve this inquire 
Cheers,
