Feature Name

Inputs from hostDirectives in design components should be included in API docs.

The Desired Behavior

i,e. in Callout, these inputs from hostDirectives should be included in API docs.

hostDirectives: [
    { directive: DaffArticleEncapsulatedDirective },
    { directive: DaffManageContainerLayoutDirective },
    {
      directive: DaffTextAlignableDirective,
      inputs: ['textAlignment'],
    },
    {
      directive: DaffCompactableDirective,
      inputs: ['compact'],
    },
    {
      directive: DaffColorableDirective,
      inputs: ['color'],
    },
  ],

All other information within these directives do not need to be exposed in the API docs. The enduser should only care about the input they can use.

Your Use Case

As a user, I would like to know what inputs from hostDirectives are available for use.
