TreeGrid Document Library view

[vban]

Has anybody implemented treegridview for document library? I have a custom type with the 0-many associations with cm:content and/or cm:folder and want to display custom properties of the parent and be able to expand on demand to display children with their properties as well…
I've not found tree grid in YUI available out-of-the box, is it possible to use a component from ExtJS in Share?
many thanks

I'm not aware of any existing implementations, but there is certainly nothing to stop you using any other JS framework (such as ExtJS). You just need to ensure that your WebScript component is importing the correct JavaScript/CSS resources that are required.
