RapidWeaver Stacks add-on info: Responsive Grid – made to be fast and simple… as it can be! But still with many advanced features if you need them. The grid will adjust to the width of the screen but with an option to define a max number of 'boxes' (max-width).
The Grid Box Stack is an extra Stack that'll allow you to define the content as an animated button.
Special features: Option to turn the entire Grid Stack into one GIANT RESPONSIVE NAVIGATION GRID.
