Hi,can anyone please tell me how to achieve the following. I have three divs the first div, mainNav, is visible and contains 5 links. One of the links in mainNav should open up the div, firstSubMenu, which holds 8 more links. one of the links in the firstSubMenu should then open up the div, secondSubMenu, which holds 5 links. The other links (the links that does not show a div) in mainNav should hide the firstSubNav and secondSubMenu divs if they are visible. The other links in firstSubMenu (the links that does not show a div) should hide the secondSubMenu div if it is visible. I have the following code which does an ok job but the problem is that the links in mainNav doesnt close the seconSubMenu if it is open. Please tell me how to solve this problemo.

So, by clicking on SSub 5, you hide:

FSub 1, FSub 2, FSub 3, FSub 4, FSub 5, FSub 6, FSub 7, and FSub 8?

You might want to go without the [object] alert, too. That was just testing, tho. Right? ;-)

yeah the alert is just for testing purposes :)
No the SSub links shall not hide any divs. In the mainNav div, one link should be able to hide and show the div firstSubMenu, all the other links in mainNav should hide the firstSubMenu div if it is visible. Also, all the links in in mainNav shall close the secondSubMenu div if it is visible. All the links in the div firstMenuSub shall close the secondSubMenu if it is visible, except for one link which should show and hide it depending on visibility.

What is the innerHTML, or containing text of this link? Which one?

On the first set of links, I simply added the hide() function after the first function you had.

Can I throw something in?
No? Well, I will, despite your protestations. 

onClick="javascript:hide(document.getElementById('secondSubMenu'))"

There's a fair amount of this going on, and you could do away with most of it.

1. 

javascript:

Use of this pseudo-protocol is unnecessary in an event handler.
That can go.

2. 

document.getElementById(....)

There is a test for support of this method inside the functions that are called. If the method is not supported
(IE4 & NS4), then the error would have already occurred in the event handler.

IMHO, for this reason, and to make the code shorter, it would be better to put this part inside the functions... 

onClick="hide('secondSubMenu')"

then 

function hideshow(id){ 
    if (document.getElementById)
      var which = document.getElementById(id)
    else
        return;
    if (which.style.display=="none")
    ..etc..
