Description

Use case

I want to show/hide some fields based on the value of other fields (selectModel) which has custom object as options/values.

Problem

The DynamicFormRelationService does the relations match on the matchesCondition function using strict equality which when comparing objects returns false.

Proposed Solution

Add an optional function called matched to the DynamicFormControlCondition which, in case it is defined, it will take precedence over the current value property.

export interface DynamicFormControlCondition {
    id?: string;
    rootPath?: string;
    status?: string;
    value?: any;
    matched?: (relatedFormControlValue: any) => boolean; // Has precedence over value
}

This way we can match the value correctly.
