Originally, at the top of Tiki sites, there was a rectangular area a single text line high containing the Tiki version info, the date and time, and a search form. Later the Tiki info was moved to the page footer, the date was removed and a horizontal menu was added.
In a few Tiki releases, turning on the Top Bar also activated the other site identity items at the top of the page such as the logo and banner ad space, but these areas are now available by default; there's no "Top Bar" master switch for them.
As of Tiki 3(?), the Top Bar typically contains a horizontal menu and a search form (and possibly "breadcrumbs" links).
Example: {if isset($objectCategoryIds) and in_array(2, $objectCategoryIds)} {menu id=43 css=y type=horiz}{else}{menu id=44 css=y type=horiz}{/if}
Note: The page content below is rather old but could be useful as an example of what can be put in the site menu custom code form.
For other example, how to use the Custom Site Header instead of the Top Bar see : Custom Site Header and Look and Feel.
Example for your Site Title :
<h1 style="color: #FFFFFF; padding-left: 20px; padding-right: 40px; padding-top: 8px">Your Site Title</h1>
Example for your Site Logo :
<img src="img/your_logo.png" width="200px" height="100px" border="0" style="padding-top: 5px; padding-bottom: 5px">
Example for each Navigation Button :
<h2 style="color: #FFFFFF; padding-top: 10px; padding-left: 20px; padding-right: 20px">Articles</h2>
Creating some more different User Menus for each feature-area (articles, wiki, gallery, trackers etc.) and setting specific permissions to this menus (integrated in modules) according to your user groups, you can now let appear a different collection of menus (on the left or right side) after a user has clicked on one of the navigation buttons.
Combining the information you enter in the option-fields of each position of your navigation menu, there is the possibility to control the visibility of each button as well depending on the user's rights as if the feature is activated under admin panel >> features at all.
