Hi:
Please review requirements here: https://sites.google.com/site/brainletalex/
Basically, CRUD hierarchical (tree) grid with separately editable, multiple values in a single cell.
The best would be a modern HTML5, GWT or JavaScript code deployable with Java accessed NoSQL database.
Please submit your bid for such web page spreadsheet or hierarchical grid control by responding to this email.
Thank you,
Alex
