Collapsible Events

UnityEvents are a powerful way to trigger actions at the right time in your game, but they can quickly become cumbersome to manage in the Inspector. When a component contains many events, the default layout can take up a large amount of space and make navigation difficult.

To work around this, developers often resort to clunky custom attributes or even writing full custom Editors just to add simple foldouts.

Collapsible Events provides a lightweight solution. It automatically overrides the default Unity Editor PropertyDrawer for events and replaces it with a clean, compact foldout interface. Each event appears as a minimal header in the Inspector, marked with a small unobtrusive icon, and can be expanded only when needed. Collapsible Events also includes type-specific settings that allow you to hide event drawing or fall back to Unity’s default rendering for selected user or built-in components.

The result is a clean, organized, and easy-to-navigate Inspector, even when your components contain dozens of events.

Seamlessly replaces the existing drawer even when nested under other inspector elements, lists, and arrays.
