Is Multi Grouping in JqGrid Currently supported?

Question

I am currently trying to implement multi grouping in jqGrid but can't seem to get it right. See code below:

colNames:['Programme','Course', 'Fee Type','Description','Apply', 'Amount', 'Discount', 'Discounted Amt','GATE Amount'], 
                    colModel:[ 
                        {name:'programme',index:'programme', width: 25}, 
                        {name:'moduleInstance',index:'moduleInstance', width:30
                        },
                        {name:'feeType',index:'feeType', width:15
                        },                           
                        {name:'description',index:'description', width:15
                        },
                        {name:'isApplicable',index:'isApplicable', width:4, editable:true, edittype:'checkbox', editoptions: { value:"True:False"},formatter: "checkbox", formatoptions: {disabled : false} 
                        },
                        {name:'amount',index:'amount', width:5
                        },                   
                        {name:'discount',index:'discount', width:5, editable:true},
                        {name:'discountAmount',index:'discountAmount', width:8},
                        {name:'gateAmountCovered',index:'gateAmountCovered', width:8, editable:true}
                    ],sortname: 'moduleInstance',
                    grouping:true,
                    groupingView : {
                        groupField : ['programme', 'moduleInstance'],
                        groupColumnShow : [false, false],
                        groupText : ['<b>{0} - {1} Item(s)</b>', '{0}']
                    },

This only shows programme title on the header and not the other. Can anyone tell me what I'm doing wrong here?

I never implemented grouping, but i tried this code in my example and got the same result that you got. Then i looked into google and found this

This is a very old post, in 2011 but i suppose they are right, its not supported. that's why they would have come up with this multipleGroup approach. Look into this and this old answer. At least you will get some references.
