Hovering with your mouse cursor over an element can show more information: for example the option to reorder a list.
But users have no way to know that there are more options available on hover. Furthermore, there is no such thing as a hover state on (pure) touch devices. You can not hover over a screen with your finger to show additional elements.

Make sure, elements are reachable without hover and therefore by touch.
