PentaHo reporting dynamically drag and drop the field during runtime

As per pentaho documentation we can find the dynamic reporting is done in this as runtime report fields,format can be changed .I have used Prd and dashboard but these reporting will not support drag and drop feature.

I cant find enough documentation for the same. Please help me share the link for the same and which tool of penataho will be used for the same.We need to some data analysis also.

Thanks
