Tree-like Widget in Bokeh

I am still a little new to using Bokeh, but I was wondering if there exists a widget similar to a tree that could be used to display parent-child relationships in the browser window while running a Bokeh server application.

I am trying to build a query construction interface to allow users to enter new conditions to the tree (e.g. (Age > 20) AND (Name = “John” OR Name = “Jane”)). Is there a simple way to add such a feature using Bokeh or would this require some external packages? In either case, could someone please point me towards an example to help me get started with this?

Hi,

There is nothing currently built into the core library that would provide this. However, Bokeh is extensible, so i would be possible to create a custom widget that does this (probably by wrapping some other existing JavaScript library for a tree-widget). The documentation for extending Bokeh has more information and several examples:

  http://bokeh.pydata.org/en/latest/docs/user_guide/extensions.html

Thanks,

Bryan
