Rest Api group collections and subcollections

For example there is 150 collections - The aim to get these collections in Groups.

For example:
Electronics - main category

  • Camera & photo - sub category
  • Cell phones & accessories - sub category
    — Headphones - sub category of sub category
  • Television & video - sub category

for example resultis :
name - Electronics
id - 2222222
collection id -0

name - Camera & photo
id - 4444444
collection id -2222222

OR

get navigation menu of grouped collections

OR
Group collections and hide it and use it only for API - to get structured collections with the name of Main collection

All options are good - even if its somehow with tags or whatever

Please help me. and if its possible in more details

Hey @SardorAlif

Can you please elaborate - are you trying to create groups to then use in the Online Store, or use the API to fetch specific groups of products?

Nope I need to group by category collections - and get it from REST API, to create in our app some kind of menu with submenus.
Just I have about 150 collections - and they are not grouped by similarity

For example:
Electronic

  • Cell phones
  • TV
  • Headphones
  • Video
  • Accessories

Clothing

  • T-shirts
  • Pants
  • Hoodies
    and etc
