David Chen commented on SAMZA-277:
----------------------------------

I am thinking rather than making this table collapsable, it might be better to 
just add a search box that will filter the table as you type, similar to the 
GitHub file search (https://github.com/apache/incubator-samza/find/master). 
There are a couple of options we can go with for the behavior of the search box:

1. Filter to display rows whose keys start with the search query.
2. Filter to display rows whose keys or values contain the search query 
(basically ctrl-f).

I am leaning more towards (1) because I am more in specific properties, but I 
can see how many people would fine (2) helpful as well since doing ctrl-f on 
the page might be more cumbersome if the table is very large.

What are your thoughts?

> 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.
