## Description

MultiType is an Android RecyclerView adapter and UI component toolkit designed to map multiple data types to distinct layouts within a single scrolling list. It functions as a multi-type view manager that automates the association between diverse data models and their corresponding view holders.

The library includes a data-to-view expander that transforms single data objects into multiple list items, allowing complex information patterns to be represented across several rows. This mechanism enables the representation of complex data lists through object-to-item expansion.

The system manages heterogeneous content styles by handling dynamic view type resolution and type-to-layout mapping. It further simplifies UI development by decoupling view logic from specific holder declarations to reduce manual boilerplate during custom view binding.
