expand single row in custom visual using matrix dataview?

[jprdynamicapps]

Is there any way for a custom visual to expand/collapse a single row in a matrix dataview? My client wants +/- expand as implemented in the stock matrix.

It looks like the visual is given data at whatever level is currently expanded and there is no indication of whether a leaf node has children, true? Is there any way for a visual to request a level of data?

The hierarchy slicer source code available on git implements row expand/contract, but it does it by getting a table datasource, which includes all of the data needed for the tree, but does not include summary data for parent rows as provided by the matrix dataview.

Appreciate any assistance.
