That’s great.
The second problem is also strange, there seems to have been bugs with the dropdowns and positioning of elements in Safari before but since I run Windows I can’t really troubleshoot it with newer versions of Safari.
Are the dropdowns coming from the template or added by you? In case it’s the former and the template is old, maybe they were developed when Webflow had bugs and some strange things are happening there.
Try to recreate them with a new dropdown element & new classes, publish and see if it solves the problem.
