We have a sidebar menu (left in screenshot) that uses a floating group element and it looks great on 15" devices and fills the full height of the viewport (thanks to Zerocodes plugin). However on zoomed in screens or smaller screens elements are getting cut off and there is no way of scrolling.
so, how can I add a scrollbar that appears when there are elements cut off by the height of the viewport?
All elements, icons and the sidebar are fixed width.
May not fit your use case, but I have found if I set the floating group to be positioned to both (rather than top or bottom) and you stretch it to the end of your page, it will fit to the content and scroll when the page height gets smaller
I know it’s an old post, but I had a similar problem which I fixed by changing Vertically Float Relative from Top to Nothing for the page element. Then the sidebar scrolls with the page.
