reorder_grid_columns

Description​

Enables the possibility to reorder grid columns by drag and drop

reorder_grid_columns: boolean

Example​

gantt.config.reorder_grid_columns = true;
gantt.init("gantt_here");

Default value: false

Details​

This functionality works both in grid and resource view.

The property provides two CSS classes:

  • .gantt_column_drag_marker - the CSS class of the marker that specifies the position the dragged column will be placed to
  • .gantt_grid_head_cell_dragged - the CSS class of the dragged column

Events​

You can handle the behavior of grid columns while they are dragged and dropped via internal events of the grid: onBeforeColumnDragStart, onAfterColumnReorder, and onColumnDragMove. For example:

snippet "onBeforeColumnDragStart"/"onColumnDragMove":

gantt.attachEvent("onGanttReady", function(){
      var grid = gantt.$ui.getView("grid");
      grid.attachEvent("onBeforeColumnDragStart", function(column, index){
        // custom code
        return true; // return false to cancel dragging a column
      });
      grid.attachEvent("onColumnDragMove",function(
          dragColumn, targetColumn, dragIndex, targetIndex){
        // custom code
        return true; //return false to cancel reordering to this position
      });
});

and snippet "onBeforeColumnDragStart"/"onAfterColumnReorder":

gantt.attachEvent("onGanttReady", function(){
      var grid = gantt.$ui.getView("grid");
      grid.attachEvent("onBeforeColumnDragStart", function(column, index){
        if(column.draggedColumn.name == "text"){
              return false;
        }
        return true;
     });
      grid.attachEvent("onAfterColumnReorder", function(object){
        // get the config of a column after reordering
        console.log(object)
      });
});
