How to to center the submenu under main menu in jquery css menus?

Q: Dear Support,

I would like to make the submenu center aligned under the main menu items.
Is it possible?

A: The submenu is left aligned by default. It is not possible to center the submenu.
The width of the menu item depends on the text. The more text you input, the wider menu
item becomes.

But it is possible to make the same width fro submenu as menu.
It is possible to change the width of the menu and submenu items manually.
For this purpose you should open your page and find the CSS3menu code, for example, to set
the width 200px you should add style="width:200px;":

<li class="topmenu" style="width:200px;"> style="height:18px;line-height:18px;"><span>Item 3</span>
<ul style="width:200px;">
<li>Item 3 0</li>
<li>Item 3 1</li>
<li>Item 3 2</li>
<li>Item 3 3</li>
<li>Item 3 4</li>
<li>Item 3 5</li>
