By using Widget:Radio button, this template is able to display multiple layers of {{BlockGrid}}, in order save space, and better visualise a structure.
Usage[]
Each layered blueprint requires a unique name, a set of single-letter abbreviations for each icon being used (same as BlockGrid), then a layer title and layer art pair.
A layer title is an anonymous parameter starting with ----, then the layer's name. Layer art is defined similar to BlockGrid, except the entire layer is a single anonymous parameter, instead of separate ones for each line. Empty lines should contain at least a single space, otherwise they may be removed.
The layer which is selected by default can be changed by setting |default= to the desired layer's name.
