jQuery sortable nested div issue - not getting placeholder to drop

I need to able to move the outer div below or above the inner div. It can be inside the inner div as well, placeholder is not getting displayed.

If there is already a div available below or above inner div, then it is displaying placeholder.

Here is my code:

$(function() {
  var cancelDrag = false;
  $(".section").sortable({
    connectWith: ".section, .inn_column",
    items: '.row',
    receive: function(event, ui) {
      console.log($(ui.item));
      if ($(ui.item).hasClass("inn_portlet")) {
        $(ui.sender).sortable("cancel");
        cancelDrag = true;
        $(this).sortable('cancel');
        return false;
      } else {
        cancelDrag = false;
        //$(ui.item).find('input:radio')[1].checked = true;
      }
    },
    start: function(event, ui) {
      console.log('start');
    },
    stop: function(event, ui) {
      console.log(cancelDrag);
      console.log('stop');
    },
    update: function(event, ui) {
      var newIndex = ui.item.parent().attr('class');
      var oldIndex = $(this).parent().attr('class');
      console.log(cancelDrag);
      console.log(newIndex);
      console.log('update');
    },
    sort: function(event, ui) {
      console.log('sort');
    },
    change: function(event, ui) {
      console.log('change');
    },
    out: function(event, ui) {
      console.log('out');
    },
    over: function(event, ui) {
      console.log('over');
    },
    //handle: ".row-header",
    //cancel: ".inn_portlet",
    placeholder: "row-placeholder ui-corner-all"
  });
  $(".inn_column").sortable({
    connectWith: ".inn_column, .section",
    //items: '.row, .inn_portlet',
    //handle: ".row-header",
    //cancel: ".row-toggle",
    placeholder: "row-placeholder ui-corner-all",
    start: function(event, ui) {
      console.log('el start');
    },
    stop: function(event, ui) {
      console.log(ui);
      console.log(event);
      console.log('el stop');
    },
    update: function(event, ui) {
      console.log('el update');
    },
    sort: function(event, ui) {
      console.log('el sort');
    },
    change: function(event, ui) {
      console.log('el change');
    },
    out: function(event, ui) {
      console.log('el out');
    },
    over: function(event, ui) {
      console.log('el over');
    },
  });
});
