This sample demonstrates a center-aligned horizontal main menu with relative position inside a table cell on the page.
The following settings are used for the main menu in the last section (i.e. MENU TREE FEATURES) of the configuration file (c_config.js):
// MAIN-MENU FEATURES
'horizontal', // ItemsArrangement ('vertical','horizontal')
'relative', // Position ('relative','absolute','fixed')
'0', // X Position (values in CSS valid units- px,em,ex)
'0', // Y Position (values in CSS valid units- px,em,ex)
false, // RightToLeft display of the sub menus
false, // BottomToTop display of the sub menus
...
To center-align your horizontal main menu in a table cell you should just nest your menu tree in a center-aligned table with auto width - e.g.:
<table align="center" border="3" cellpadding="3" cellspacing="0">
<tr>
<td>
<ul id="Menu1" class="MM">
...
</ul>
</td>
</tr>
</table>
