is there a way to create a figma prototype where you can resize components in prototype mode? i’m trying to resize components on drag (i.e. stretch navigation bar)
Yes, there is! In prototype interactions, there is an option called “on drag”.
You should design two states for your component, one collapsed and one expanded. then set the “on drag” prototype arrow. Make sure your animation is “smart animate”. Also, make sure your hierarchy of layers and naming in both states are the same. then, you’ll get what you want.
