Hello,
thank you for the effort. This is pretty much the exact same solution that I came up with myself when I built my own sample (from which my screenshots came). We have a fake view at the bottom that looks like it is a part of the drawer content but actually is a separate view. Unfortunately this is not "good enough" UI for me since it does not move up when you pull up the actual drawer content.
Is it maybe possible to use the SfBackdrop control instead and have it expand from the bottom instead of the top?
