An interactive version of a Reingold–Tilford tree. Click on the nodes to expand or collapse. From http://bl.ocks.org/mbostock/4339083
Added search, expand and styling of results and its ancestors. Visible from http://bl.ocks.org/PBrockmann/0f22818096428b12ea23
Thanks for sharing your solution!
Is it also possible to clear the search result by cklicking on a second item? So there is at most one result highlighted in red?
