# ModelBlockAlignmentAttributesMapping

typedef

Defines the mapping of block alignment options for a model element attribute.

Each key represents a logical alignment name (e.g. `'left'`, `'center'`, `'right'`, `'justify'`), and the corresponding value describes how that alignment is represented in the model — including the actual attribute value and whether it should be treated as the default alignment for the element.

Used by features that need to determine whether a model element supports block alignment and how to apply it. Can be provided as a static object or as a function receiving the element and returning the mapping dynamically, via [`blockAlignment`](module_engine_model_schema-ModelAttributeProperties.md#member-blockAlignment).
