# Welcome to the Multi Module Tree Documentation!
The 4App Multi Module Tree provides all the means to implement a tree in a layout that can handle objects from more than one Core Engine module. For example, to configure the display of module folder
and module files
together in one tree. The multi-module tree can display both related and unrelated modules.
The best way to integrate a multi-module tree is by referencing layout multi_module_tree
in your target layout. The layout and basic required actors are part of this 4App.
For unrelated modules, a ChildLoader
needs to be configured according to the required modules/fields.
After installation, the new layout and corresponding actors are available to refer to.
