submenu position problems with css


Poster: bluecrane
Dated: Thursday August 14 2003 - 7:23:20 BST

Greetings all,
My first post so go easy on me...I'm having a problem with submenus and their postion in relation to the parent. It appears what is causing the problem is a css that I have defined for the web project that I'm working on.

Here's a site that has what I'm talking about: http://www.venomdirect.com/menu.htm And the code fragments that show the problem are below. Without the css file the demo menu works fine...with the css file the submenus have bad offsets.

The problem has got to be in the top and left values within the lh-col section of the css I just don't know how to fix it.
TIA!

Code: Select all

css:
<head>
<meta http-equiv="Content-Language" content="en-us">
<meta http-equiv="Content-Type" content="text/html; charset=windows-1252">
<title>New Page 1</title>
</head>

<body>

<pre>#hdr{

        background:#9D9C63;
        color:#000000;
        border:solid #000000;
        border-width:2px 0px;
        margin:40px 0 0 0;
        }

#lh-col{
        position: absolute;
        top: 160px;
        left: 20px;
        width: 180px;
        margin: 0;
        padding: 0;
        }

#rh-col{
        margin: 8px 20px 20px 200px;
        border: 2px solid #000000;

        color: #333333;

:roll: Showmenu names don't match... one has a space, caps and no caps.
Hope that's all it is :)

Morning maz,
The problem happens on my real code as well. The code fragments (and site sample) are from Andy's demo code with changes to include the css.

In any case it looks like the showmenu names are case insensitive.
cheers,

Is what you show as "css:" supposed to be your my.css file? If so, I don't recognize that as a css file (I'm by no means a css guru, but I do use it every day).

A css file should be only css statements, not an HTML file. In your case...

Code: Select all

#hdr{
        height:30px;
        background:#9D9C63;
        color:#000000;
        border:solid #000000;
        border-width:2px 0px;
        margin:40px 0 0 0;
        }

#lh-col{
        position: absolute;
        top: 160px;
        left: 20px;
        width: 180px;
        margin: 0;
        padding: 0;
        }

#rh-col{
        margin: 8px 20px 20px 200px;
        border: 2px solid #000000;
        background: #ffffff;
        color: #333333;
        position :relative;
        padding: 20px;
        }

That's it.

Not sure about case sensitivity, but I think I'd make them match anyway.

Hey John,
How bizarre, my "real" css file doesn't have the embedded html...I removed the html stuff from the css file on the sample site and still have the same problem.

I completely agree with yours and maz's comment regarding case for the showmenu, my point was that I was using excerpts from Andy's demo code. :|

I forgot to mention in my first posting what a cool product the menu is. There are simply too many other satisfied users for this to be a bug...just can't find my darn problem.
regards,

Couple thoughts (from far out in left field!)...

1. Can you specify a <div> before the <body>; i.e., shouldn't it be body/div?

2. You show a subOffset spec in the code for both top and left. Could this be messing with the css (or vice-versa)? REM them both out and see what happens.

3. As for case, Andy probably has that covered, but out of habit I just like to keep things the same.

He's on this section right now. Maybe he'll straighten us both out!

John,
Also forgot to thank you and others on this group for the help you have/are providing to myself as well as others :!:

On your first thought: I moved the body tag outside of the div tag and still no luck.

2nd: I commented out both "_subOffsetTop=5;" and "_subOffsetLeft=-10;" (I think that is what you wanted)...also doesn't work.

Some observations:
1) _subOffsetTop and _subOffsetLeft "appear" to have no effect on the results of my test on the test site.

2) However, changes to both Top and Left in the lh-col section of the css file DO adversely effect the submenu. (basically what you surmised above). To demonstrate, I changed my.css lh-col section top=10 instead of top=160 and you will note that the submenu does look closer to the parent however still not where you would want it. See sample site to observe: http://www.venomdirect.com/menu.htm The higher value of "top" the greater the offset of submenu.

I really need to absolutely position the left hand column (lh-col) and menu and I would like to do it in the css file...just don't know how to get around the conflicts.
cheers,
-bluecrane

You're right. It's a very powerful and stable menu system. The fault is probably too many tweakable options for us mere mortals!

Out of all the problems I've seen on this forum, none have been due to bugs in the software.

Big difference. Maybe just a little more tweaking in the css will bring it home.

Andy (above) is correct. It's extremely rare for there to be a bug in the menu code itself. Typically it's a browser fault (which Andy (other Andy) seems to always find a workaround for), or (I hate to say this) - us! This thing can be a bear to fully understand, and I hate to think what it's like writing it :!:

Keep at the css and let us know what happens.

My biggest concern here is that changes in the .css file are effecting the submenu where the behavior should be derived from the menu config file, in this case: vertical_data.js. There is a relationship between my css file and the vertical_data.js file that I'm simply not understanding.

As you can probably tell I'm new to the web authoring gig however I do have an extensive background in application development...which leads me to the questions:
1) Is this a scoping problem?
2) Since I'm putting the menu in the lh-col section (through html usage of the class within the css) the section's top and left seem to coincide with the menu's top and left...how can I limit the scope of either so that the values are treated separately?

Good Morning bluecrane :D

Positioning of my second menu made no sense at all and I had to individually place the offset values.

Although I have no clue as to what you are talking about now, I think that position="relative"; is a bag of worms, have you considered adoption? :?

maz
Is it the journey or the destination?

Hey maz,
Thanks for the input. I think that I have arrived at a solution based upon other posts found in this forum.

Since the conflicts are occuring between my css file and the menu config file vertical_data.js I have added Top and Left with offset values to the submenu. Not the elegant solution I had hoped for but it works.

To illustrate, see the code fragment. Note that on the test site, http://www.venomdirect.com/menu.htm, that I have only changed the first menu item (Support) that has a submenu...the other menu items are unchanged.

Code: Select all

   with(milonic=new menuname("support menu")){_c=1
   top = "offset=-10";
   left = "offset=-20";
   borderwidth = 1;
   style = mainStyle;
   overfilter="Fade(duration=0.2);Shadow(color='#777777', Direction=135, Strength=5)"
   outfilter="randomdissolve(duration=0.2);Shadow(color='#777777', Direction=135, Strength=5)"
   aI("text=Milonic Disussion Forum;url=http://www.milonic.com/menu/forum");
   aI("text=Menu Support Mailing List;url=/mailman/listinfo/menu-dev;target=_blank");
   aI("text=Paid Support Page;url=http://www.milonic.com/menu/reqhelp.php");
   aI("text=Frequently Asked Questions;url=http://www.milonic.com/menu/faq.php");
   aI("text=Version Information;url=http://www.milonic.com/menu/versioninfo.php");
   aI("text=Licensing;showmenu=licensing");
   }


This is really only a hack to get it to work. If I decided to change values within the css file I'd have to also change values in the vertical_data.js file (through trial and error).

I'd still love to hear ideas from others on how I could limit the scope effect of the css file.

regards,
-Troy
