Lets say i've the following data structure

Option A
Option B
 Option B1
 Option B2.1
 Option B2.2

I am trying to create an enums stucture that allows this so I can generate a dropdown based on the value of the previous selected dropdown.

Examples :

Select option A -> No additional dropdowns
Select option B -> Generate dropdown with Option B1
Select option B1 -> Generate dropdown with Option B2.1 and Option B2.2

This would work when you want to create an array with childeren is there anything similar possible for enums

 "$schema": "http://json-schema.org/draft-07/schema#",

 "definitions": 
 "medicine": 
 "type": "object",
 "properties": 
 "value": "type": "string" ,
 "categories": 
 "type": "array",
 "items": "$ref": "#/definitions/medicine" 
 
 
 
 ,
 "properties": 
 "person": "$ref": "#/definitions/medicine" 
 

And then the enum structure to be something like this

[
 
 "value ": "Option A" 
 , 
 
 "value ": "Option B ", 
 "categories ": [ 
 
 "value ": "Option B1 ", 
 "categories ": [ 
 
 "value ": "Option B1.1" 
 , 
 
 "value ": "Option B1.2" 
 
 ] 
 
 ] 
 
]

So I am looking for a data structure that would allow me to make dropdowns based on the values selected here in a own layout generation engine.

Have you considered flattening your structure so that it's easier to look up options and sub-options?

Let's imagine that you've got an initial array for the root options:

[
 'opt_a',
 'opt_b'
]

Then you have a flattened map of all options from which you can derive labels and subsequent dropdowns:

 opt_a: 
 label: 'Option A'
 ,
 opt_b: 
 label: 'Option B',
 children: ['opt_b1']
 ,
 opt_b1: 
 label: 'Option B1',
 children: ['opt_b11', 'opt_b12']
 
 opt_b11: 
 label: 'Option B1.1'
 
 opt_b12: 
 label: 'Option B1.2'
 

I hope this answers your question and is self-explanatory enough.
