You can reset the toolbar's position after a drag operation is completed.

First get the toolbar's coordinate which is relative to the Canvas, then translate it to coordinate relative to the bound (black area).

You can then calculate how close the toolbar's center is from each edge of the bound. If the distance is lower than a defined value, move the toolbar to the edge (to dock it), you need to rotate the toolbar 90 degrees if you dock it to the left and right edges.

Something like this.
