I'm investigating Vaadin QuickTickets Dashboard Demo application https://demo.vaadin.com/dashboard/ and would like to increase the speed of the left menu appearances on the screen. Could you please show me where this effect can be adjusted?
You need to set the css properties animation-delay and animation-duration.
Both are set to 700ms in the demo. They are created via a mixing in common.scss.
On an UX note: Disable the animation completely and always show the menu. While the animation is a nice eye catcher in an presentation. If you need to work with the application regularly, the animation will be a total annoyence.
