I’m not entirely sure I’m following your question. Are you asking how to keep the drop down menu in one place and have only the rest of the page change when people click a link in the drop down? Is the idea to have the menu code be all in one file so you don’t have to edit multiple pages to edit it?

If so I use php to accomplish that, though any server side programming language will do. They all let you include the content of one files inside another.

You could create one file called menu.php and then in your other pages add the include statement

include “menu.php”;

Is that what you were asking? If not ask again and I’ll try to do better,

How can I list my articles to appear only on one page and use dropdown menu to display them so that viewers can see and read them?

For instance, using TAX MATTERS as the page: how can I show the following articles;
-How to treat tax issues,
-PIT (Amended)Act 2011,
-How to pay less Tax,
on the same page and using dropdown menu to enable users to locate them.

I hope you understand my question.

This is an older post that may not even be necessary anymore.

If you want to use the menu code here the key is adding the depth parameter. That creates the html you need. For the css I use the suckerfish system, which I linked to at the top of the post.

Hope that helps.

I think wp_nav_menu() was introduced a version or two after whichever was the current version back in July of 2009.

As far as making sure the drop down works in IE7 that’s really more about the css and the html. As long as you can end up with the nested list structure you’re fine with your html. You’ll want to add an id or class here or there, but all browsers will be fine with the html.

I use the suckerfish system when it comes to making things work in older browsers where css alone isn’t enough. I linked to it in a few comments above. It basically adds a small bit of javascript to add and remove a class for browsers that don’t handle :hover on anything other than the link itself.

I haven’t created drop down menu in Wordpress yet but I am going to for the next project and currently researching possibilities. I need one that would work across all the major browsers and IE7.

Odds are the main navigation will be toward the bottom of the header.php file. Just know that it doesn’t have to be.

Hard to know without knowing how that particular theme is coded.
