# User Modules

P4W provides a tool to create custom user interface called module. Modules will control what can or cannot be seen and accessed by a particular user (e.g., menus, options, and fields). The use of modules helps to streamline day-to-day operations, minimizes security threats, and prevents accidental system disruption from users.

## Create New Module

To create a new module navigate to Setup > System > Modules and click 'New' button in the top right corner of the window.

From this page you can drag-and-drop (from left-to-right) the various sections and sub-sections you wish to add to a specific module. Modules are completely custom, you can add an entire section or just specific parts at a time.
