Global Expand/ collapse button for jqGrid with subgrids

Question

I am using jqGRid with subgrid configuration to display my data. I would like to have global expand & collapse button to display or hide all subgrid information. Does jqGrid library provide this feature by any means?

jqGrid has no "Expand/Collapse all". I modified the demo from the old answer which demonstrates creating on grid with local subgrids. The resulting demo you can see here:

and it has additional "+" button in the column header of "subgrids" column. If one clicks on the button all subgrids will be expanded:

I used the following code in the demo:

var subGridOptions = $grid.jqGrid("getGridParam", "subGridOptions"),
    plusIcon = subGridOptions.plusicon,
    minusIcon = subGridOptions.minusicon,
    expandAllTitle = "Expand all subgrids",
    collapseAllTitle = "Collapse all subgrids";
$("#jqgh_" + $grid[0].id + "_subgrid")
    .html('<a style="cursor: pointer;"><span class="ui-icon ' + plusIcon +
          '" title="' + expandAllTitle + '"></span></a>')
    .click(function () {
        var $spanIcon = $(this).find(">a>span"),
            $body = $(this).closest(".ui-jqgrid-view")
                .find(">.ui-jqgrid-bdiv>div>.ui-jqgrid-btable>tbody");
        if ($spanIcon.hasClass(plusIcon)) {
            $spanIcon.removeClass(plusIcon)
                .addClass(minusIcon)
                .attr("title", collapseAllTitle);
            $body.find(">tr.jqgrow>td.sgcollapsed")
                .click();
        } else {
            $spanIcon.removeClass(minusIcon)
                .addClass(plusIcon)
                .attr("title", expandAllTitle);
            $body.find(">tr.jqgrow>td.sgexpanded")
                .click();
        }
    });
