Spry Horizontal Menu Bar not working in IE

Hi! I am new to this forum and new to Dreamweaver. I recently used Dreamweaver to build a website to display my digital portfolio. I am not very good at this and don't understand much of this works. I inserted a spry horizontal menu bar for my navigation. I did change the original set up to have the background the colors I wanted and I also changed the size so it would go across the top of my page. This looks fine in Firefox and Safari but in Internet Explorer the bar displays vertically, which does not look good. Can anyone look at my code and tell me how I can fix this problem?
I appreciate any help I can get with this as I have tried everything I know.

  • Spry Horizontal Nav Bar not working in IE7

    I'm currently working on a website for South Jersey MOM

  • Spry Vertical Menu Bar not working in IE8

    I've upgraded to 1.6.1, but it still doesn't work in IE8 unless in compatibility mode.  http://jimgreenrealty.com/Test.html
    Works fine in other browsers and other Spry elements appear to work normally in IE8.  Can anyone help?
    Thanks,
    Steve B.

    If you deselect compatibility mode on IE8 the menu bar disappears (on
    all our computers anyway).  Works fine in all other versions of IE and
    all other browsers.  Updated to Spry 1.6.1 and still no avail.
    Here it is w/o the emulating statement: http://jimgreenrealty.com/Test.html
    The other pages on the site still have it.

  • Spry Horizontal Menu Bar in IE

    Hello,
    I had looked at the forums for a possible solution to this, and none of the answers I have found work for me. I have a spry horizontal menu bar with a background image. It works in Safari, Chrome, and Firefox but on IE the background image does not show. There is only a white background. I have changed ul.MenuBarHorizontal li.MenuBarItemIE to have a background image but it still doesn't show in IE.
    This is the website: fwmedpeds.net
    I am very new to this and any help is appreciated.

    If you go to your online SpryMenuBarHorizontal.css which can be found here http://fwmedpeds.net/SpryAssets/SpryMenuBarHorizontal.css, you will see the last few lines as I have previously quoted.

  • Spry Horizontal Menu bar - submenu position

    I'm new to spry so apologies in advance if this has been
    posted before.......
    I'm putting together a new site using the spry horizontal
    menu bar - I've managed to put together a CSS format which works
    well in both FireFox and IE7 EXCEPT for the position of the
    sub-menus below the main menu bar. IE7 seems to position the sub
    menu relative to the top right corner of the parent menu item.
    Firefox seems to position it relative to the bottom left corner -
    and I can't find a solution which works for both browsers. Any
    ideas?

    You must have fixed it in the meantime as I see no problem.

  • Spry horizontal menu bar and accordion panels not working when published

    Hi,
    I'm a newbie to Dreamweaver and have been asked to design an intranet site. On the site, I added both Spry widgets for a horizontal menu bar and an accordion panel. Both of these widgets work in preview, however, neither work when I publish. I uploaded the Spry asset folder (with all the CSS and JS files) to the remote server, but still no luck. What am I missing?
    Thanks.

    Despite of what you have staed, my bet is on the fact that the SpryAssets folder and/or the included files are not being found by your page..
    Open the site in FF, click on view Source and in the source code click the link to the JS file. If it can be found, it will show the content of the file and you will have the satisfaction of knowing that the page can find the file.
    If it does not show the content, you need to correct that.
    Good luck.

  • Spry Horizontal Menu Bar background image IE8 not visible.

    I have a slight problem with a horizontal menu bar that I have placed on my site and am hoping someone can help me. It views fine in Firefox, however in IE8 the top menu background image is white instead of the image I specified. Firefox image is below.
    Below is IE8 image lacking top menu background:
    I am a novice and this is driving me nuts. How can something view fine in Firefox and loose the image in IE explorer? I must have a code incorrect, I know it. Any  help is greatly appreciated.
    Thank you,

    At the bottom of SpryMenuBarHorizontal.css, you will find
    @media screen, projection
    ul.MenuBarHorizontal li.MenuBarItemIE
    display: inline;
    f\loat: left;
    background-color: #FFF;
    Change the background colour to transparent and all is well.

  • ? Horizontal Menu Bar not loading in IE

    Our horizontal menu bar does not load into IE.  It works fine in Safari, Firefox and Chrome.  It used to work on all four
    browsers so I've gone back and uploaded an older version of our site to see if I could get it to work in IE.  Even this older
    site does not load anymore, also reloaded all our older Spry Assets and CSS. 
    The Website is www.sundogexpeditions.com
    Thanks for any help and I'll provide any additional info to help diagnose my problem

    We found the problem in the ul.MenuBarHorizontal li MenuBarItemIE .  The display listed "none"  We deleted it
    and everything appears to display just fine in IE.  Not sure if this was the best fix but it works for now.
    Thanks

  • Spry horizontal menu's not displaying right in IE9

    Presently I'm using Dreamweaver CS4.  I have built a web site and placed a horizontal spry menu at the top of the web page.  It is situated on the page just below a smaller  non-spry horizontal menu.    In IE9, the menu appears above and to the right of this smaller menu rather than in the location I want it to appear.  What's more, in Dreamweaver the menu seems to float the upper right of the screen (I've attached a screen shot).   When I review the web site in IE 7, Firefox, Chrome, Opera, and Safari, the menu is correctly placed.
    Can anyone help solve this issue?  When I view the web page in IE9 and put it into IE7 mode, all is well.  Not so in IE9 (or IE8 for that matter).
    I'd appreciate direct email as well as answering it here to help others with my quandry.  My direct email address:   [email protected].
    Thank you!
    This image shows you where the menu appears in Dreamweaver AND in IE9
    This image shows you where the menu correctly displays in IE 7 (standard mode), Chrome, Firefox, Opera, and Safari.

    I'm not sure where you attached files (I have not seen a way to do that in the Forum), But I will try to speak generally and work with what you have posted.
    My suspicion is that the negative top margin you have applied is messing things up a bit.
    I also note that it is usually better to apply margins to a CONTAINER of an unordered list (which is what menus are made of), than to apply the margins to the ul itself. So, restore the margin: 0; to the ul.MenuBarHorizontal style selector and create an enclosing element that bears the margin:-45px 0px 0px 200px; though I would still reconsider the use of negative top margin.
    It is entirely possible that this simple change will help.
    Please post the HTML for the top of the <body> section, including the menu code.

  • Problem endering Spry Horizontal Menu Bar in IE7...help.

    I have created a horizontal menu bar in DW CS4 using Spry. When I view using live view, everything is working. When I test in Firefox and Nomad, everything renders as expected. I have tested the page www.ridedesigns/newsite/index.htm using IE7 on both a Windows XP and Vista platform. The problem is that the dropdown menu items fall on a layer behind the company logo (or so it appears) and are only partially visible behind that jpg.
    What have I done incorrectly, or is this a known bug?

    Here's how I changed the top of your page. Add these two divs:
    #menudiv {
        width: 868px;
        margin-top: 0px;
        margin-right: auto;
        margin-bottom: 0px;
        margin-left: auto;
        text-align: center;
    #maintable {
        width: 868px;
        margin-top: 0px;
        margin-right: auto;
        margin-bottom: 0px;
        margin-left: auto;
        clear: both;
    And use them this way:
    <BODY>
    <PRE> </PRE>
    <div id="menudiv">all of your menu markup here, as you have it now</div>
    <div id="maintable">
      <TABLE width="868" border="0" align="center" cellpadding="5" cellspacing="0" id="template">
        <TBODY>
          <TR valign="bottom">
            <TD height="68" colspan="5" align="left"><IMG src="./index_files/web_banner.gif" width="648" height="73" alt="Ride Designs"></TD>
          </TR>
    ...rest of table as it is now, followed by
    </div>
    In my analysis, by placing the menubar in the table, it was sinking into the universe of the table and could not rise above it with z-index. In fact, in IE, the list items in the submenus were taking on the height of the <tr> as well as falling down behind lower table rows.
    By putting both the menubar and the table into identically-positioned divs...centered by using the margin: auto; on both sides...they will sit adjacent to each other and not interfere. It did not function correctly with both menubar and table in the same div.
    Thanks for letting me dig this through you.

  • Horizontal Menu Bar not displaying when published as it views in live view or preview

    I am working on putting together our site and haven't used Dreamweaver in years so very rusty.  I have a horizontal menu bar that is working properly in "live view" and in "preview" mode but when I publish the submenus are not working. 
    You can view the site at www.pulsecc.org

    Thank you so much! That's a little frustrating how long I pulled my hair out trying to figure something this simple out!

  • My Spry Horizontal Menu doesn't work

    I created my Spry horizontal menu and tried it in preview browser and it doesn't work.  I published the site to see if it check didn't work in preview mode and it REALLY doesn't work.
    I'm sure it's something simple that I am just missing, but what I don't know.  I have attached the css style sheet as I did change the spacing and colors.
    Is it something I could be missing on the individual pages and linking there?
    I apologize for being dumb, but I am a newbie to this and the tutorials I took don't go into detail about linking other than to explain the linking from your index page.  Is there more linking that I need to do?
    Here is the menu and I did place it in it's own div tag.
    <ul id="MenuBar1" class="MenuBarHorizontal">
        <li><a href="index.html">Home</a></li>
        <li><a href="#" class="MenuBarItemSubmenu">Bar Code Products</a>

    I thought that was all there was to it.
    What am I missing.  I can link to one page, but have to click on the back button to view any other page and keep repeating that process to view all the pages.
    Boy do I feel stupid.
    Any help would be appreciated.  Needless to say I republished my friends old site because of functionality.  But I'd really like to get this one working for him.
    Thanks in advance.
    Oops

    NEVER MIND.  What an idiot.  I never copied the linked menu bar into the other pages.  My stupid.

  • Spry Horizontal Menu Bar width problem in IE and Safari

    Hi Everyone,
    I am working on a template and have used Spry Horizontal Menu for quite a few sites now. This one is giving me problems though on the width of the navigation bar.  It moves the last right menu item to the next row on the left in Safari and IE and Chrome, but looks perfect in Firefox.  I'm using a googlefont for the text. As I have quite a few menu items I have them set to 'auto' width.  Is there a fix to make all the others look like it does in Firefox or do I need to shorten my menu items by changing titles/reducing padding, etc.?
    Working page can be viewed at www.ikanizi.com/index2.html
    Many thanks. 

    Anyone who increases their browser's text size will see the same thing.  For wiggle room, reduce top-level links from 11 to no more than 7.

  • CS3 Fix for Spry Horizontal Menu bar/drop boxes positioning bug in IE?

    I have searched threads to see if there is an "easy" solution for the incorrect positioning of horizontal menu bar drop boxes in IE browser older versions(mine showed up at the top of the screen and mysteriously included the word "false" in older IE ONLY). Is there a downloadable patch or quick fix for this problem at this point in time? I saw an available download for a newer version of Spry but seems like overkill for this small issue. I am not an experienced web designer or computer geek, but can follow specific directions I am given. The horz bar with drop boxes showed correctly in Firefox and other browsers but not in older(?) IE. For now, I've simply removed the drop boxes to make the page look respectable, but boy did it look good with those boxes. I am hoping somebody can talk to me without lots of teckkie terms. Though I appreciate and love all of you tecs out there.

    You really should install the Spry update as it fixes some IE issues that the earlier versions of Spry had. Then use the Dreamweaver Command menu to update your Spry files within your site and you should have the latest and be ready to go. If you're still having issues you may want to also check out the Spry forum: http://forums.adobe.com/community/labs/spry
    Let us know if the update doesn't solve your particular problem.
