vBulletin custom theme breadcrumb issue

[SpiderZq]

Hi, I'm getting a problem with my custom theme breadcrumb. I have no idea how to fix it.

Right now it looks like this

As per my needs it would be looks like this, "only increase the breadcrumb_height when user will open the thread link"

Here is navbar code:

<div id="navbar" class="navbar"><div class="navWrap">
    <ul id="navtabs" class="navtabs floatcontainer<vb:if condition="$show['member'] AND $notifications_total"> notify</vb:if>">
        {vb:raw template_hook.navtab_start}
        {vb:raw navigation}
        {vb:raw template_hook.navtab_end}
    </ul>
                <vb:if condition="$show['registerbutton']">
                    <div class="registerButton">
                        <a href="register.php{vb:raw session.sessionurl_q}" rel="nofollow">{vb:rawphrase register}</a>
                    </div>
                </vb:if>

</div></div>

<!-- Custom Content Wrap -->
<div id="breadcrumb" class="breadcrumb"><div class="bcWrap">
    <ul class="floatcontainer">
        <li class="navbithome"><a href="index.php{vb:raw session.sessionurl_q}" accesskey="1"><img src="{vb:stylevar imgdir_misc}/navbit-home.png" alt="{vb:rawphrase home}" /></a></li>

        {vb:raw navbits.breadcrumb}
        {vb:raw navbits.lastelement}
    </ul>
    <hr />

    <vb:if condition="$vboptions['enablesearches']">
            <div class="searchBoxMain">
                <!-- search form -->
        <form action="search.php?{vb:raw session.sessionurl}do=process" method="post">
            <vb:comment><input type="hidden" name="s" value="{vb:raw session.sessionurl}" /></vb:comment>
            <input type="hidden" name="securitytoken" value="{vb:raw bbuserinfo.securitytoken}" />
            <input type="hidden" name="do" value="process" />
                <ul>
                    <li class="searchText">Search</li>
                    <li><div class="searchInputBox"><input class="searchInput" type="text"  name="query" tabindex="99" value="" /></div></li>
                    <li><input type="image" src="{vb:stylevar imgdir_themedir}/searchButton.gif" value="Search" alt="Submit" tabindex="100" /></li>
                </ul>
                </form>
                <!-- / search form -->
            </div>
    </vb:if>
</div></div>

                </div>
            </div></div></div></div>
        </div>
        <div id="contentMain"><div class="contentWrap">
            <div class="contentLeft"><div class="contentRight">
                <div class="contentTL"><div class="contentTR"><div class="contentBL"><div class="contentBR">
                    <div class="contentBodyWrap">
<!-- Custom Content Wrap End -->
<div class="body_wrapper1">


{vb:raw ad_location.ad_navbar_below}
{vb:raw ad_location.global_below_navbar}

<vb:if condition="$show['notices'] AND THIS_SCRIPT != 'register'">
    <form action="profile.php?do=dismissnotice" method="post" id="notices" class="notices">
        <input type="hidden" name="do" value="dismissnotice" />
        <input type="hidden" name="s" value="{vb:raw session.sessionurl}" />
        <input type="hidden" name="securitytoken" value="{vb:raw bbuserinfo.securitytoken}" />
        <input type="hidden" id="dismiss_notice_hidden" name="dismiss_noticeid" value="" />
        <input type="hidden" name="url" value="{vb:raw return_link}" />
        <ol>
            {vb:raw notices}
        </ol>
    </form>
</vb:if>

Here is navbar_link code:

<vb:if condition="$show['breadcrumb']">
    <li class="navbit"><a href="{vb:raw nav_url}">{vb:raw nav_title}</a></li>
<vb:else />
    <li class="navbit lastnavbit"><span>{vb:raw nav_title}</span></li>
</vb:if>

Your help is much appreciated
