MenuKit

What is MenuKit?

MenuKit is a UI and inventory framework for Fabric mods. It lets mod developers add custom inventory slots, persistent containers, panels, buttons, and HUD overlays using simple builder chains — no boilerplate, no manual packet sync, no NBT wrangling.

Most Fabric UI libraries only handle screens and widgets. MenuKit goes deeper: it manages real inventory slots that persist across sessions, sync between client and server automatically, and integrate with vanilla's shift-click and container systems.

Features

• Custom inventory slots — add real, functional slots to the player inventory with automatic NBT persistence and client-server sync
• Panel builder — declarative layout with rows, columns, padding, relative positioning, and context-aware placement (survival, creative, containers)
• Button system — toggle buttons, icon buttons, dynamic tooltips, conditional visibility, and pressed/disabled states
• Button attachments — inject buttons above any container region without touching the target mod's code
• HUD overlays — panels anchored to screen edges with conditional visibility and custom rendering
• Mod families — group multiple mods under one shared keybind category and unified config screen
• Shift-click routing — directional control with priority slots, per-panel opt-in/opt-out
• Slot decorations — filters, ghost icons, slot locking, empty-click handlers, background tints
• Region system — organize container slots into named regions and groups for bulk operations
• Creative mode support — automatic slot repositioning between survival and creative layouts
• Standalone screens — full-screen custom UIs with the same slot and panel APIs
