{name: 'name', index:'fullname' }

  {name: 'fullname', index:'fullname', hidden: true }

…

   groupingView    : {
            groupField               : ['fullname'],
            groupColumnShow : [true],
            groupDataSorted    : true,
   }

I need fullname hidden all time no matter what groupColumnShow's value.  Maybe, we should use 3rd arg (such as 'auto', null) to tell it no actiion (show/hide) thie col defined by groupColumnShow but let the col  controled by colModel's setting ('hidden').

Would it be possible use custom-defined col different from the col in groupingView  ?

I wonder grouping on name-col but display the value from fullname-col, code like this:

 {name: 'name', index: 'name' },
 {name: 'fullname', index: 'fullname'},

…

groupingView    : {
        groupField         : ['name'],
        groupText         : ['<strong>{fullname}</strong> - {1}'],
        groupDataSorted : true
}
