How to create a component with custom settings?

Question

1C-Bitrix

Good afternoon, tell me where to look for information or documentation on the following issue.
I want to make a Mega menu component. So that by means of dragging and dropping elements you can collect multi-level drop-down menus.
It will be necessary to make a list of all categories and products, as well as pseudo-items for connecting with logic, on the one hand and simply drag and drop to another column and there we already collect a menu from this. So here's how to get products and categories, it's just everything there by api, but I can't understand how to make modules in the admin panel. And also how to put your custom js menu collection script there.
I hope I explained my thoughts well. Thanks for answers!
