Hello,

First of all thanks for choosing our Theme, we are glad to be you in the WoodMart WordPress family :-).

I saw the screenshot you attached. To change the behavior of MyAccount link as sidebar.
Go to WoodMart >> Header Builder >> Edit Header >> Edit Account module >> Form Display >> Sidebar.
