Custom Creative Mode Inventory? (1.19.2)

[The Typholorian]

Hi! I want to make a gui that works almost exactly like the creative inventory. I currently have the GUI and keybind working well, I just need help on what to put in render. I have 6 pages that I want to add, but I think I can figure out how to add the images. My current problem is having one tab for your inventory and all the others just having the hotbar on the bottom. I checked what MCreator does for that, and it is about 150 lines of code. There must be a simpler solution. Also, a couple of the tabs would have buttons and such instead of infinite items. 

Edit: No, I can't just create creative inventory tabs. I want a completely separate GUI so you can find the tabs when playing with massive modpacks. 

Note: I am fairly new to modding, and would prefer snippets of code or tutorials I can follow.

Загрузите на github, что есть на данный момент, я посмотрю.

I suspect you want to do something similar to JEI.

Find items for each mod in a separate tab?
