SelectItem with grouping without display group field

[wallytax]

Is it possible to have a editable grid with a SelectItem as one of its fields and displaying a grid op options (pick list) that is grouped by a field which in itself is not displayed.

For a normal grid, I believe you can set "detail: true" for a field to prevent it from being shown. I have moderated the example about grouping and it works.

isc.ListGrid.create({
    ID: "countryList",
    width:522, height:224,
    alternateRecordStyles:true, cellHeight:22,
    dataSource: countryDS,
    // display a subset of fields from the datasource
    fields:[
        {name:"countryName"},
        {name:"government"},
        {name:"continent", detail: true}, // HERE THE MAGIC HAPPENS
        {name:"countryCode", title:"Flag", width:40, type:"image", imageURLPrefix:"flags/16/", imageURLSuffix:".png", canEdit:false}
    ],
    groupStartOpen:"all",
    groupByField: 'continent',
    autoFetchData: true
})

I attempt to do the same in a data source field:

        fields: [
          {name: 'id', hidden: true, primaryKey: true, type: 'integer'},
          {
            name: 'function_id',
            align: 'left',
            displayField: 'name',
            optionDataSource: functionsDataSource,
            pickListFields: [
              {name: 'name', title: 'Name', width: '*'},
              {name: 'group', detail: true} // HERE THE MAGIC NOT HAPPENS
            ],
            pickListProperties: {
              groupByField: 'group',
              groupStartOpen: 'all',
              showHeaderContextMenu: false
            },
            pickListWidth: 325,
            required: true,
            type: 'integer',
            title: 'Function',
            valueField: 'id',
            width: '*'
          }

detail:true is a property for a DataSourceField and affects treatment across multiple different components. For a ListGridField (what pickListFields is), use showIf:"false" to hide a field.

Great, didn't know this property was available.
Thanks for your response.
