Multi level grouping, summary and grand totals for Ext JS 4.2
I'm happy to release this feature to everybody interested in the subject. Here is a list of what you can do with it:
- multiple levels of grouping, of course
- summaries for each grouping level
- grand total
- hide grouped headers
- you can reconfigure the groups via the columns menu
- you can even add additional columns to existing ones via columns menu
I didn't test remote summary for it.
Soon I will add this to github for anyone interested in enhancing this.
