[kakachiex2]

Hi everyone, I am developing some personal tools for ComfyUI but I'm relatively new to code I have knowledge on HTM, CSS and JavaScript but I'm experimenting a lot, so this is my LLM chat node loading inside a custom node. but I want to create my own design node for my tools I attach my idea so I need recommendation on how I can create my own custom node correctly and integrate it in ComfyUI.

LLM chat node:

And this is and image loader I want to implement with this exact design bypassing the ComfyUI defauld widget.

Any help I'll appreciate thanks.
