How to retrieve Item/Holding Data via hostComponent in Custom Components

[YuktiClarivate]

Accessing host component instance
You can get the instance of the component your custom component is hooked to by adding this property to your component class:
@input() private hostComponent!: any;

In one of our custom components, we are using this approach to obtain the ISBN.
For ISBNs, we know that the value is stored in the following path:
hostComponent.searchResult.pnx.adddata.isbn

For Items and Holdings, after the corresponding state transitions (e.g., clicking to expand the Holding section), is it possible to retrieve their data through hostComponent in the same way? Alternatively, is there another recommended method for retrieving these values?

Related case: In case 08262084, there are several display-related limitations that are difficult to resolve at this time, and the available display space is also limited. Therefore, we are considering customization as an alternative solution.

We are exploring applying this to components such as .
The fields we are considering placing through customization include Barcode, public note, and similar values.

Hi Yukti-san,
Thank you for sharing the question. (I am the one who originally submitted this inquiry to Clarivate.)

After further investigation, I created an Angular component that outputs both the host component and the app store to the console for debugging purposes.
Through this verification, I learned that if we need to retrieve information such as item data, we can obtain the correct hostComponent by placing the custom component at the position where that specific information becomes available (e.g., ).

Both the host component and the app store contain a large amount of data, so it would be greatly appreciated if the official documentation could be expanded in the future to provide more guidance on these areas.
