What is disableSelection used for in jQuery UI?

Question

Can someone help me understand why is this useful and when to use it?

$( \"#sortable\" ).disableSelection();

Answer 1

It's useful if you want to make text unselectable. If, for instance, you want to make drag-and-drop elements with text on, it'd be annoying to the user if the text on the box accidentally would get selected when trying to drag the box.
