How to use FlexMonster components to achieve multi-level continuous roll-up and drill-down?

Hello, Peter,
Thank you for your question!
Our component is designed to support hierarchies with multiple levels. You just need to specify the hierarchical structure in your data. Have a look at the following example: http://jsfiddle.net/flexmonster/mr0Lwkab/. After you click 'Add data types' button, each Country on the grid will show the '+State' option for drilling down.
Hierarchical structure with levels for CSV is specified this way:

Category,Category:Subcategory,Category:Subcategory:Model,D4+Date,Orders,Sales
Accessories,Bike Racks,Hitch Rack - 4-Bike,7/25/2003,1,120

Category, Category:Subcategory and Category:Subcategory:Model are levels of one hierarchy. Please pay attention to D4+ prefix in this sample data source. It indicates that Date field is a date and will be displayed as a hierarchy: Year > Quarter > Month > Day. Here is the tutorial listing available data types for CSV: https://www.flexmonster.com/doc/managing-data-presentation-csv/.
Please let me know if the above information was helpful.
Regards,
Tanya

Hi Peter,   The default behavior when double-clicking on a certain area of the chart, which is drilling through, can be either enabled or disabled. It cannot be redefined right now. But this can be done for the grid using a celldoubleclick event handler. Please let me know how critical this feature is for you.   Also, could you please let me know if your company has already purchased a license of Flexmonster and if yes, what is the name of your company? This information would be helpful to us.   Kind regards, Iryna
