Cursor style

Position the cursor when dragging an object. By default, the cursor appears in the middle of the dragged object. UsecursorAtthe option to specify another position relative to the draggable (specify pixel values relative to top, right, bottom, left). By providing ancursoroption with a valid CSS cursor value, customize the appearance of the cursor. Valid CSS cursor values include: default, move, pointer, crosshair, etc.

Handles

Only allow dragging when the cursor is over a specified part of the draggable. Usehandlethe option to specify a jQuery selector for the element (or group of elements) used to drag the object.

Or do not allow dragging when the cursor is over a specified element (or group of elements) within the draggable. Usecancelthe option to specify a jQuery selector that cancels the drag functionality.

Snap to element or grid

Snap the draggable to the inner or outer boundaries of a DOM element. Usesnap、snapMode(inner, outer, both) andsnapTolerance(the distance, in pixels, between the draggable and the element when snapping) options.

Or snap the draggable to a grid. Use thegridoption to set the size of the grid cells (height or width in pixels).

Visual feedback

Provide feedback to the user, like dragging the object with a helper.helperThe option accepts the values 'original' (moves the draggable object with the cursor), 'clone' (moves a copy of the draggable with the cursor), or a function that returns a DOM element (which is displayed near the cursor during dragging). Useopacitythe option to control the opacity of the helper.

To distinguish which draggable is being dragged, keep the draggable in motion on top. If dragging, usezIndexthe option to set the helper's high z-index, or usestackthe option to ensure that when dragging stops, the last dragged item always appears above other items in the same group.
