* When using GetBlockGridHTML() to render the Block Grid, the alias will be rendered in the markup as a 'data-area-alias' attribute. Use the alias attribute to target the element for the area. Example. .umb-block-grid__area[data-area-alias="MyAreaAlias"] { ... }
This Areas Alias must be unique compared to the other Areas of this Block.
Override the label text for adding a new Block to this Area, Example: 'Add Widget'
