Description

Currently the opening of parent menu item uses a delay of 300ms which cannot be changed.

I suggest moving the delay to an option so that this can be configured.

Contributor guide

Research direction
Locate where the 300ms delay is hardcoded in the menu widget source code (likely in jquery.ui.menu.js) and add a new option for the delay following the existing option pattern.
