v2.4

- Menu autoclose feature

- Fixed bug with open and close mouse overs

- Add autoclose and fade demo to example page









Notes:



If you want a menu to be open initially set the style display to

"inline" in the subMenu class div like this...

<div class="subMenu" style="display:inline;">





The fading effect can be disabled by setting the 

doFading var to false. I have only tested this feature on 

ie 6, Netscape 1.7, firefox 1 & 1.5



If the user has cookies enabled the script will bake a cookie ;) on

the browser to track the state of the menus. This is good news for those

of you who don't use frames, you can now have persistent menu states



Make sure you put the java script include tag after all the menus otherwise

it will not be able find and initialize them. If you have questions, or comments

about the XpStyle Menu v2 send me an email.



And lastly a plug for myself, If you need some professional help with technical

web development please drop me an email, I do contracts for a competitive price. :)

                                                        if your going to do this its a good idea to set the CSS item .subMenu to display:none; */
