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

Caveat emptor: .disableSelection() is actually harmful on some browsers, as it prevents clicking active elements (e.g. textareas) inside the sortable.

• Firefox 33.1 for Mac OS X (Yosemite): .disableSelection() prevents clicking on embedded textarea; doesn't seem to have any effect otherwise (i.e. it is still impossible to select text with the mouse in the sortable if omitted)
• Chrome 39.0.2171.71 (64-bit) for Mac OS X: .disableSelection() seems to have no effect whatsoever.
