Enable hot menu in horizontal layout

Is it possible to enable the sub menu of hot menu in ecommerce template to display horizontally?

I have already installed and made changes to the ecommerce template. I really like to implement the mega menu in it so that all my products direct link can be display in the menu (as quick links).

Is this possible? Possible to share the php code? I am fine if I need to edit the menu links and name in php if it cant be modified via the administrative interface.

But menu in that template acts exactly like that (horizontal sub-menus)?
See demo.hotjoomlatemplates.com/index.php?template=ecommerce
Maybe you changed Menu style in module parameters?
it's 'List' by default.

Mega menu is currently not supported by your template.
You can try to port megamenu to that template if you are familiar with html and css. You can look at Cars template source to see form of input html for it.
Also you can order custom work from me to make you that port.

The 2nd layer submenu is now vertical. I tried to change it to nav2 but it does not become horizontal.

how much is the porting/customization fees for mega menu?

The price for custom ordered porting of megamenu to ecommerce template would be 80$.
