I have been searching for this for a couple of days and found a lot of places are telling me to edit the navigation file however when i look in this file i cant see where it is structuring my navigation menu.

When i inspect my navigation on my webpage the structure is

<ul> -> beginning of the list 
<li> 
<ol> -> first column of nav
<li> ->items in column 
<ol>-> Second column of Nav 
<li> ->items in column
<ol>->3rd column of Nav
<li>->items in coloumn 

But i want it to be

<ul> -> beginning of the list 
<li> 
<ol> -> first column of nav
<li> -> All items in 1 column 

I have put my navigation.php below because i cant find where it references the structure as i cant see any ol tags.

So i just need to know 1. if i am looking in the correct place for the structure of the navigation and 2. how to edit it? if you need any more info please just let me know.

My Main aim is to have the All Categories menu in a straight line on the home page and have it as it is on the rest of the website. If i am going about this the wrong way please let me know.

Thank you in advance

  • Tried enabling template path hints from admin panel? – TBI Infotech Jul 31 '14 at 10:01
  • i did that it pointed me to top.phtml where i found the code <?php $_menu = $this->renderCategoriesMenuHtml(0, 'level-top', 'sub-wrapper' ) ?> then it just echoed 'menu' so i found the renderCategoriesMenuHtml function in the Navigation.php – Adam Allen Jul 31 '14 at 10:03
  • From re-looking at the element on my webpage i think i may need to find the div "sub-wrapper" as that is the div my structure is in. But i have no idea where to even start looking for that – Adam Allen Jul 31 '14 at 10:05
  • what magento version are you working on, and do you want to show this categories in sidebar? – TBI Infotech Jul 31 '14 at 10:55
  • 1.9.0.1. No not really we want the all categories top navigation to be dropped down on just the front page so it is already visible when the page loads up. However if it is better practice to have the categories in a side bar and just use CSS to make it look like it is dropping down from the top and disable the mouse over on the home page (so the all cats cant drop down) i could talk to my manager about it. We are both new to magento so dont know what the best way of doing this would be. if this has confused you, let me know and will get screen shots for you – Adam Allen Jul 31 '14 at 11:02

Starting with version CE 1.7 the top menu is not generated by Mage_Catalog_Block_Navigation anymore.
Instead Mage_Page_Block_Html_Topmenu is used.
This one dispatches events that basically let you add anything in the main menu.
By default the categories are added via an observer.
And each menu item is rendered by the method _getHtml from the same class.
I think that's what you are looking for.
