Как изменить группу строк Datatables, чтобы разрешить только 1 открытую группу?

Я использую этот скрипт для расширения/расширения групп строк в таблицах данных.

var collapsedGroups = {}; //1

rowGroup: {
    // Uses the 'row group' plugin
    dataSrc: 'data',
    startRender: function(rows, group) {
        var collapsed = !!collapsedGroups[group]; //2
         
    //LOOP THREW EAH ROW
    rows.nodes().each(function (r) {
        //SET DISPLAY = NONE
        r.style.display = 'none';
        //IF COLLAPSED (OPEN)
        if (collapsed) {
          //SET DISPLAY = SHOW
          r.style.display = '';
        }
    });

   // Add category name to the <tr>. NOTE: Hardcoded colspan
  return $('<tr/>')
     .append('<td></td>')
     .attr('data-name', group)
     .toggleClass('collapsed', collapsed);
  }
},

//ON CLICK BTN EXPAND
$(document).on('click', 'i.fa-angle-down', function() {
    //GET TR DATA NAME
    var name = $(this).parent('td').parent('tr').data('name');
    //
    collapsedGroups[name] = !collapsedGroups[name]; //3
    //
    table.draw(false);
});

С помощью этого кода я могу открыть несколько групп одновременно.
Теперь я стараюсь, чтобы одновременно была открыта только одна группа.

Я попытался изменить obj CollapdGroups на var:

var collapsedGroup; //1
var collapsed = collapsedGroup; //2
collapsedGroup = name; //3

Но это не сработало.
Как я могу изменить код, чтобы разрешить только одну открытую группу за раз?

Вам нужно собрать data-name из <tr> в событии завершения розыгрыша, а затем при нажатии <tr> изменить collapsedGroups другого имени на ложное, например:

$(document).ready(function() {
  var collapsedGroups = {};

  var table = $('#example').DataTable({
    paging: false,
    order: [
      [2, 'asc']
    ],
    rowGroup: {
      // Uses the 'row group' plugin
      dataSrc: 2,
      startRender: function(rows, group) {
        var collapsed = !!collapsedGroups[group];
        rows.nodes().each(function(r) {
          r.style.display = 'none';
          if (collapsed) {
            r.style.display = '';
          }
        });

        // Add category name to the <tr>. NOTE: Hardcoded colspan
        return $('<tr/>')
          .append('<td colspan = "8">' + group + ' (' + rows.count() + ')</td>')
          .attr('data-name', group)
          .toggleClass('collapsed', collapsed);
      }
    }
  });
  let namesTable = [];
  $('#example').on('draw.dt', function() {
    namesTable = [...document.querySelectorAll('#example tr[data-name]')].map(el => el.dataset.name);
  });

  $('#example tbody').on('click', 'tr.group-start', function() {
    var name = $(this).data('name');
    namesTable.forEach(el => {
      if (el !== name)
        collapsedGroups[el] = false;
    });
    collapsedGroups[name] = !collapsedGroups[name];
    table.draw(false);
  });

});

Я добавил код с чистым js (потому что я предпочитаю его), но вы можете изменить его с помощью jquery, если хотите.

Чтобы изменить группу строк Datatables, чтобы разрешить только одну открытую группу за раз, вам нужно отслеживать текущую открытую группу и закрывать другую, когда открывается другая группа. Я надеюсь, что код, которым я поделюсь ниже, решит вашу проблему.

var currentOpenGroup = null;
var collapsedGroups = {};

$('#example').DataTable({
    rowGroup: {
        dataSrc: 'group',
        startRender: function(rows, group) {
            var collapsed = !!collapsedGroups[group];

            if (group === currentOpenGroup) {
                collapsed = false;
            } else if (currentOpenGroup !== null && collapsedGroups[currentOpenGroup] === false) {
                collapsedGroups[currentOpenGroup] = true;
            }

            rows.nodes().each(function (r) {
                r.style.display = collapsed ? 'none' : '';
            });

            return $('<tr/>')
                .append('<td></td>')
                .attr('data-name', group)
                .toggleClass('collapsed', collapsed);
        }
    }
});

$(document).on('click', 'i.fa-angle-down', function() {
    var name = $(this).parent('td').parent('tr').data('name');

    if (name === currentOpenGroup) {
        currentOpenGroup = null;
        collapsedGroups[name] = true;
    } else {
        currentOpenGroup = name;
        for (var group in collapsedGroups) {
            if (group !== name) {
                collapsedGroups[group] = true;
            }
        }
        collapsedGroups[name] = false;
    }

    $('#example').DataTable().draw(false);
});

Ваш код не работает, проверьте его на скрипке.
