Using nb_inputs: 2 with select inputs

Title:

How to Render Dual Selects with Options in Rule_Value Section

Body:

Description:
I'm working on a project where I need a rule that requires two select inputs in the rule_value section. I'm attempting to create a rule where a user can select values from two different dropdowns. However, I'm encountering difficulties in understanding how to properly supply these select inputs with their respective options.

Code Snippet:

{
    "condition": "AND",
    "rules": [
        {
            "id": "159",
            "field": "159",
            "type": "collection_string",
            "input": "select",
            "operator": "In",
            "value": [262, 261],
            "nb_inputs": 2,
            "values": {
                0: [ /* first select options */ ],
                1: [ /* second select options */ ]
            }
        }
    ],
    "valid": true
}

Specific Issue:

I am not clear on how to populate the values object for both selects. Should these options be set in rule.filters? I need guidance on how to format this part of the configuration, specifically how to properly define and pass the option values for each select input.

Attempts:

I have looked through the documentation but couldn't find a clear example or explanation that fits this specific scenario. I also checked the provided examples and tried modifying them to suit my needs but with no success. Further I have tried passing in a values prop like the one above.

Request:

Could you provide an example or guidance on how to correctly set up dual select inputs within a rule, including how to supply each select input with a set of options? A small code example or a reference to the relevant part of the documentation would be greatly appreciated.

Environment:

jQuery-QueryBuilder version: 0.1.2
Browser: Edge 122.0.2365.52
Thank you in advance for your assistance!

Start with the existing documentation and examples for nb_inputs, select inputs, rule_value, and filter configuration in jQuery-QueryBuilder 0.1.2; compare them with the reported values object and rule.filters question. Done means providing or documenting a clear dual-select configuration example, including how each select receives its options.
