Not Responsive! Really?

I hope this is my error. I have spent days setting up the Directory plugin and getting it ready and testing… only to find out that it is NOT responsive.

How do I make the Directory work on iPhone/mobile sites?

I tried both the Grid and the List settings. No go.

Note too, thet the List setting does not work in the full screen view either — the sub categories are not listed properly; the subcategories of the upper category are shown in the category below it.

Can this be fixed?
