Container Preview
by Xeonz
Container Preview shows the contents of a shulker box, bundle or ender chest directly in the item tooltip, so players can inspect a container without opening it.
What it does
Hovering over a container item in the inventory shows its stored items in a standard tooltip. Containers placed inside other containers can be viewed as nested previews, and a lock mode keeps the tooltip still while a player inspects a single item in detail. Support for Shulker Boxes, Bundles and Ender Chests is built in, and it works with custom backpacks and other expanded storage mods without extra setup.
The mod targets 26.3 and the 1.21.8 – 26.3 builds, published for Fabric, Forge and NeoForge, and it requires Fabric API on Fabric. Container Preview is client-side only, so servers run without it, and players who join a server need nothing extra. Its code is not open source; the author holds All rights reserved, while the source code and issue tracker are public.
Key features
Direct tooltip previews
Hovering over a container shows its exact contents within the standard item tooltip.
Nested previews
Containers stored inside other containers can be explored several levels deep from the tooltip.
Detail lock modes
A lock mode freezes the tooltip so a single item's details can be read without the interface shifting.
Configurable layouts
Full grid support and a choice of layout options let players pick a clean view for the preview.
Broad storage support
Works with vanilla containers and many storage mods, including custom backpacks and bundles.

Use cases
Checking a shulker box mid-build
A builder can confirm which blocks sit inside a shulker box without placing it on the ground.

Bundle contents appear at a glance, so the right item is found without opening the bundle.
Who it’s for: Players who carry many containers and want to check their contents from the inventory, and server owners who run mixed storage setups.
