Windows Exlporer-Like Tree View

[buildthewall]

It would be great to have an expandable/collapsable tree-view kind of chart.  Kinda like windows explorer. 

We are planning to use FusionCharts' drilldown functions to allow our users to narrow down a dataset.  Say starting with a bar chart showing sales totals by month.  Then drill down on "January" to go into the Tree View control.  Each node on the tree might start out as product category.  The user could then expand a product category to show individual orders for that category.

Finally....we would like to allow users to click on an individual order and jump into our app's data entry screen for that order.

- Product A

Order 393933939 (click me to go to data entry screen via the link)

+ Product B (collapsed)

+ Product C (collapsed)

Thanks.

Hi,

Thanks for your suggestions. However, we personally feel that since there are so many JavaScript tree view components readily available, a Flash tree component wouldn't scale that well for the following reasons:

1. JavaScript tree components can expand the parent container horizontally/vertically when needed - this allows for better visual rendering. In Flash, we've a fixed movie size, which we cannot dynamically increase. As such, scroll bars would appear, which thereby decrease usability in a tree.
2. JavaScript tree can easily take loads of 10,000+ nodes. In Flash, parsing that amount of XML and rendering can be processor intensive

However, we'll definitely push this idea to our R&D to see if we can come with a better solution.

I have exactly the same need. Can somebody address me to some Java hierachical tree example I can use?
