# A Data-Driven GUI Library for Minecraft Mapmaking > **Click (https://github.com/AjjMC/ajjgui) for more information.** This datapack allows mapmakers to create and maintain complex and robust item-based GUIs in-game. This is achieved by dragging and dropping items with custom SNBT in containers within a world, which the datapack can use to generate GUIs. It functions as a black box that treats each item as a graphical widget with predefined properties, and the user is not expected to modify any files. Two types of GUIs can be created: * **Block Entity GUIs:** Placed at a fixed position and shared by all players. These are generated upon compilation. * **Chest Boat GUIs:** Retrieved from a database and accessible anywhere by specified players only. These are obtained directly from the above by (https://github.com/AjjMC/ajjgui/blob/main/README.md#porting-guis-to-players). Benefits: * SNBT standard for quick and easy creation of advanced item-based GUIs. * Completely in-game workflow, with the entire datapack being a black box that the mapmaker can ignore. * Robust design, support for multiplayer, including personalized GUIs, and no interference with player inventories. * Complete documentation, in-game tutorial, and demos. * 5+ years of continuous maintenance, built with the most up-to-date practices, and powering prominent maps officially featured on Minecraft Realms.
