Hi all,

On a client website I need to display the nav bar on two rows, splitting evenly at the halfway point.

Eg:
Item1 - Item2 - Item3 - Item4
Item5 - Item6 - Item7 - Item8

or

Item1 - Item2 - Item3 - Item4
Item5 - Item6 - Item7

I tried to use

<% if Pos = TotalItems / 2 %> and variations of that but kept getting PHP errors. The generated PHP code showed that the <% if ... %> had not been interpreted (still showed as the <% %> tag) whilst the <% end_if %> tag had been interpreted - causing the error.

below is the code I have been playing with from my Navigation.ss file

<ul>
   <% control Menu(1) %>
      <% if Pos = TotalItems / 2 %>
   </ul>
   <ul>
      <% end_if %>
      <li><a href="$Link" title="Go to the $Title.XML page" class="$LinkingMode">
      <% if Pos + 1 = TotalItems / 2 %>
      <span class="last">$MenuTitle.XML</span>
      <% else_if Last %>
      <span class="last">$MenuTitle.XML</span>
      <% else %>
      <span>$MenuTitle.XML</span>
      <% end_if %>
      </a></li>
   <% end_control %>
</ul>

Can anyone offer some suggestions? I have good PHP skills but my knowledge of Silverstripe is still growing

If your navigation items have a fixed with, you can do this in CSS only. Just set the width of the container element to 4 * the width of a navigation item and set float: left on the navigation items...

Creating the custom control is what I'm sure I have to do but it doesn't seem to be working. I'm not sure I'm using the variables of $Pos and $TotalItems correctly:

   function NavSplit () {
      return ($Pos == $item->XML_val("TotalItems",null,true) % 2 ) ? true : false;
   }
   
   function NavBeforeSplit () {
      return ($Pos == ($item->XML_val("TotalItems",null,true) % 2) - 1 ) ? true : false;
   }

NavSplit should return true if the current item is the middle item (ie the first item of the second row). NavBeforeSplit should return true if the current item is the last item of the first row.

I'm not sure these functions will work correctly because of the cacheing.
