How to create a new list display type in Bitrix24?

Question

Bitrix24

Boxed version.
The task is to create a new type of displaying a field of the "Binding to infoblock elements" type, first in the lead card. For example, I want the elements to be displayed in a separate window, laid out in a certain way. In this case, the standard views should also be preserved. So far, we have only been able to add a drop-down list element in the edit field, but this is just markup. The value is not saved.
It is necessary to save the selected type for the field, and subsequently so that the field in the lead is displayed as needed.
The second day I can’t find anything ((. Tell me, please, where to dig?

Bitrix24 does not imply such a possibility without changing the system core (which is not desirable within Bitrix24, but I would say it is strictly contraindicated within Bitrix24).
You can copy an existing type and create your own based on it, however this is not an operation described in the documentation and you will need to figure it out yourself.
Articles by third-party authors can help in part, but you can find them yourself by searching for "Bitrix custom field type"
