Tina, I have exactly the same issue. After looking at your website, I see that the jerks happen only on the dropdown menus. This is exactly how my navigation menu is behaving. I have rebuilt this menu 3 times with exactly the same results. Does anyone have a fix?
@Joanetta please share your site. For Tina's site, it seems to be caused by how she has the page structured, specifically the left column that is the full height of the page.

One other thing I noticed and not sure if this causing the jerking when clicking on the drop down menu. You have mixed content on the page - specifically the custom fonts are all http and should be https. You can fix this in two different ways. First, go to your Custom Fonts and re-select the font file, making sure the file name is https. Another way is to go to Elementor>Tools>Replace URL and do a search / replace of your domain url. Enter your domain with http and then in the next field to the right, enter your domain with https. Your custom fonts are not showing when I view your website.
Shaunm, thank you! I'm seeing the shift on all the dropdown menus - Performance Tours, Theme Tours, MUN UN Conferences, Payment Info. When I move from left to right clicking on each dropdown, the Performance Tours doesn't shift. But the other three dropsdowns do. Then if I move back across the menu from right to left, all the dropdowns shift, including Performance Tours. Thank you for the information about mixed content and custom fonts. Haven't had much experience yet with custom fonts. This could certainly be part of the issue.
