GlassMenu class

A liquid glass context menu that morphs from its trigger button.

GlassMenu implements the iOS 26 "liquid glass" morphing pattern where a button seamlessly transforms into a menu. The same glass container transitions between button and menu states using spring physics.

Features

  • True morphing: Button transforms into menu (not overlay)
  • Smooth spring physics: Gentle settle with no harsh bounces (stiffness: 300, damping: 24)
  • Liquid swoop: Subtle 5px parabolic arc for seamless down-and-up motion
  • Seamless crossfade: Button only appears at final 5% to preserve morph illusion
  • Dimension interpolation: Width, height, and border radius morph smoothly
  • Position aware: Menu expands from button position
  • Settings inheritance: Inherits parent layer settings like GlassCard (thin rim by default)
  • No button animation: Trigger button remains static, only shape morphs
