How to add the wholesale signup form to the top navigation bar of your store?
Updated
To display the Signup Form on the storefront, click on Content from the admin panel and then select Menus from the list.
From the Main Menu, select Add Menu Item at the bottom.
Give a name to your Signup Form option and add the link by punching in the Signup Form URL. You can copy your signup form link from here. (Dashboard > Wholesale signup form)
Once done, simply hit Save Menu and the Signup Form is going to be visible, in the menu, on the storefront by the name you’ve just given it.
