Sticky Column stuck in width

Hi, i have a responsive page with a menu on left side. The menu is rounded by a sticky container. Every time ich resize the width of the browser the menu resizes but doesn’t stretch to full width of the given place. Any Ideas? Thank you

Hi, can you provide a working codepen which reproduces this and provide some more information like the exact Foundation Sites version that you use?

Have the same issue, have you worked around it?
