MenuKit

MenuKit is a client-side UI library for Fabric mods. It provides reusable interface components and the systems that place them on screen, so mods can build menus, HUD overlays, and in-game UI without writing Minecraft interface code from scratch.

Components: buttons, toggles, checkboxes, radio buttons, sliders, dropdowns (single and multi-select), text fields, labels, tooltips, icons, item displays, progress bars, dividers, and scroll containers.

What it does:

• Places UI in four contexts with one set of components: the HUD, vanilla menu screens, named slot groups, and standalone screens.
• Groups components into panels, each a bounded region that renders, takes input, and shows or hides as a unit.
• Positions panels by screen region and resizes them to fit automatically, wrapping and scrolling as needed, at any GUI scale.
• Lets several mods add UI to the same screens without conflicting: components from different mods register cleanly and coexist (panels sharing a region stack in order instead of overlapping), so mods built on MenuKit stay compatible with each other.
• Exposes slots created through MenuKit: Containers to every MenuKit consumer, so a mod can read and address another mod's custom slots, not only its own.
• Handles modal overlays, click-through prohibition, recipe-book awareness, and cursor stability across screen changes.

MenuKit is client-only and ships primitives rather than taking over Minecraft's UI. Its types are vanilla types (a MenuKit slot is a real Slot), so it coexists with other mods. Requires Fabric. For custom container menus and slots with server-synced state, add MenuKit: Containers.

Install

Working examples

MenuKit's validator mod is the honest reference consumer, with real, compiling usage of every primitive. The full surface is documented in the javadoc.
