David Chen commented on SAMZA-277:
----------------------------------
I am using the jQuery TreeGrid plugin for this:
http://maxazan.github.io/jquery-treegrid/examples/example-bootstrap-3.html
Currently, the AM is printing the config table directly. TreeGrid determines
which rows to collapse based on the CSS classes, which specify the parent
relationships between nodes/rows. As a result, I am having the webapp print the
contents of the config as JSON and then construct the table itself using
JavaScript.

> Key: SAMZA-277
> URL: https://issues.apache.org/jira/browse/SAMZA-277
> Project: Samza
> Issue Type: Wish
> Affects Versions: 0.6.0
> Reporter: Jakob Homan
> Assignee: David Chen
> Fix For: 0.8.0
>
>
> Our configs are hierarchical (x.y.z) and can be quite numerous. We can now
> sort the table, but it would be great to be able to collapse and expand bits
> of the table based on the hierarchy.
> * A complete collapse table would show just the {{x}} sections.
> * Expanding one level down would show {{x.y}} values, both those to be
> further expanded and those that are fully expanded.
> * etc. for each level.
> This would make it easy to quickly jump from one bit of config to another. I
> poked around, looking for a jquery library, but didn't immediately see a good
> match. Most of the hierarchical tree libraries are for file systems, which
> doesn't really fit here.
