Task Resizing

Task resizing allows the users to change the start or duration of an existing task using drag and drop.

Task resizing is enabled by default.

• Resizing is disabled for task groups in Auto mode, and for milestones.
• You can disable resizing for all tasks using taskResizeHandling = "Disabled"
• You can disable resizing for selected tasks using resizeDisabled property when loading the task data or during task customization.

JavaScript

Example

gantt.onTaskResized = function(args) {
  gantt.message("Task resized.");
};
