Multi-line TextInput box?

In general I've found it very difficult to find information on Bokeh widgets in the documentation, so maybe this is already possible, but is there a way to specify a paragraph-sized TextInput box? I'm using one for the user to be able to edit some code in a domain-specific language, which is awkward to do in a single-line box.

If multiple lines are not possible, is there at least a way to change the size of the box?
