Css Float Overlapping

tdktank59 · Sep 11, 2009

I have no idea whats causing this.
I have tried setting z-index on the menu (the menu that is floating under the grid)
I have no idea if IE7+ fixes this problem...
Im guessing it has something to do with multiple css emelemts on the menu...

Broken (IE6)

Correct (FF)

Menu:

Code:

<ul class="sf-menu sf-vertical menu">

        		<?php if ($this->session->userdata('username')) { ?>
        		    <li><?php echo anchor('dashboard','Dashboard',array('title' => 'Dashboard')); ?></li>

Part of the issue is with IE6's dropdown lists. The dropdown control in IE6 is not a true HTML control, but rather a Windows Forms control. So it's taken out of context of any flows or z-indexes, thus the dropdowns sitting on top of the hover menus. Conventional solutions won't work for this. I've seen some hackish solutions from Google searches, but YMMV in terms of implementing them into your markup and stylesheet. I think multi-select listboxes also fall into this category, but I'm not 100% certain.

Another issue is that IE6 can't handle transparency that well. So if your images on the rounded corners are PNG files with layer transparency, there's another hurdle. There's a ton of free javascript "include" files that manage to get around the PNG transparency issue, and these are very simple to implement.

I believe both of these issues are corrected in IE7, which may or may not be feasible as an upgrade in your work environment.

Yeah,

Well first off IE6 is a must... Government environment and everything... (Why they haven't gone to 7 I do not know but what ever)

I don't care about the transparencies, those just make it look nicer...

And my solution to the select boxes at the moment is to hide them... I think ill end up having a box pop up when they want to filter and then close when they run the filters.
that way its not "on the page" during normal operation.

I just quickly looked over the code and the only thing that comes to mind is I don't see the positioning for the z-index to work.

You must have position absolute or relative for z-index to work otherwise the setting is worthless. http://www.w3schools.com/css/pr_pos_z-index.asp

I think that will fix your problem.
