📘 Get and Description of Garry's Mod Inventory System : https://osgmod.com/gmod-scripts/3939/gmod-advanced-inventory-system

Gmod Advanced Inventory System is a very good quality customizable inventory system that you can blend into any gamemode and even run without any gamemode.

You love it when people wonder if they are still on gmod. This will be the case.
In Simple Test, when you saw the first 6 screenshots, were your reactions: "This is not Gmod anymore" or "Which game is it on?" or "Is it really Gmod?

If so, this is the exact reaction your players will have with this inventory system, I want users to arrive on the server and feel like they are on a game of their own and not just another copy of a successful DarkRP, my system works well without any gamemode, it's what I call a standalone script, that is to say that it can work alone without any other addon or gamemode

Dare to exploit your creativity, that's the goal of Garry's mod. Don't just install an addon with no freedom of customization that will make your server a copy of another.

Features will be added over time. And your suggestions. Feel free to read the wiki page of this script for more in-depth information.
