Best way to show a hierarchical tree report in APEX 4.2

Question

I have a hierarchical query spanning four levels over two tables.  The query works great and also includes hierarchical sum columns (i.e. the parent shows the sum of all children) using functions.
I'm wondering what the best way to display this data to users is?
At the moment I'm thinking I would have a collection holding my report with an extra 'show' column.  Then I would include HTML to set the correct show/hide values and refresh the report when a node is clicked.  I feel this would probably work but it can't be the best way.
I stripped down my query to the columns needed (no sum columns) and the APEX tree regions work nicely for this.  Is there any alternative jquery plugin or anything that people have experience with that will give me the native 4.2 tree structure whilst also allowing me to display extra columns with links?
If I need to provide any more info just let me know!

The best you can do is to concatenate multiple columns into single with some separator. I have not tested give a try it might resolve your issue.
with data as (
select 'M'              as link_type,
      null            as parent,
      'All Categories' as id,
      'All Categories' as name,
      null            as sub_id
  from demo_product_info
union
select distinct('C')    as link_type,
      'All Categories' as parent,
      category        as id,
      category        as name,
      null            as sub_id
  from demo_product_info
union
select 'P'              as link_type,
      category parent,
      to_char(product_id) id,
      product_name    as name,
      product_id      as sub_id
  from demo_product_info
union
select 'O' as link_type,
      to_char(product_id) as parent,
      null                as id,
      (select c.cust_first_name || ' ' || c.cust_last_name
          from demo_customers c, demo_orders o
        where c.customer_id = o.customer_id
          and o.order_id    = oi.order_id ) || ', ordered'
      ||to_char(oi.quantity) as name,
      order_id as sub_id
  from demo_order_items oi
select case when connect_by_isleaf = 1 then 0
            when level = 1            then 1
            else                          -1
      end    as status,
      level,
      name ||'--->' || parent  as title, ---- This way you can concatenate multiple columns
      case when link_type = 'M' then '#IMAGE_PREFIX#Fndtre11.gif'
              when name = 'Mens' then '#IMAGE_PREFIX#wparea.gif'
              when name = 'Womens' then '#IMAGE_PREFIX#wtpaint.gif'
              when name = 'Accessories' then '#IMAGE_PREFIX#wpaste.gif'
              when link_type = 'P' then '#IMAGE_PREFIX#cartHL.gif'
              when link_type = 'O' then '#IMAGE_PREFIX#Fndtre13.gif'
      else null
      end    as icon,
      id    as value,
      'View' as tooltip,
      null  as link
from data
start with parent is null
connect by prior id = parent
order siblings by name
