Hi,

Can anyone help me with repositioning of a Cart button please see following:

I got a tip from another helpful guy, that I should take the list item that holds the Cart button and move it to right after list item with id menu-item-3960.

And I will have to slightly decrease left and right padding on my anchors for the list item with shopping cart icon to fit after Kontakt.

My question is this:

It which template file do I find the above list items ?

I am using Genesis with Metric Child theme and woocommerce and Woocommerce Menu Cart plugins as well.
