Sélectionnez HTML Déroulant de l'Option Z-index

J'ai un select simple liste déroulante quand je vais pour sélectionner une option de Menu élément de navigation, de sorte que maintenant, quand je vais passez la souris sur les éléments du menu de navigation est de revenir à l'option de sélection de la liste qui est ouvert. Cela se passe dans tous les navigateurs. Je ne sais pas si c'est un bug ou quoi. Les étapes sont les suivantes:

  • Ouvert, sélectionnez options du menu déroulant
  • Même temps, placez le curseur sur le menu de navigation des articles
  • Maintenant les éléments de navigation sont derrière la liste d'options (pas derrière la balise select)

J'ai essayé de donner le z-index avec des positions. Mais rien ne fonctionne. Je pense que c'est pas un problème, mais ont besoin d'explication sur même. Toutes les suggestions seront grandement appréciés.

C'est l'exemple de code:

    <style type="text/css">
/* ####################   Navigation bar CSS styling   ################## */
.mynavbar {
position: relative;
width: 100%;
height: 23px; /* corresponds to 'line-height' of a.navbartitle below */
margin: 0; border: 0; padding: 0;
background-color: #666633;
}
a.navbartitle {
display: block;
float: left;
color: white;
background-color:  #666633;
font-family: Verdana, Arial, Geneva,  Helvetica, sans-serif;
font-size: 12px;
font-weight: bold;
margin: 0; border: 0; padding: 0;
line-height: 23px; /* corresponds to 'top' value of .submenu below */
text-align: center;
text-decoration:none;
}
a.navbartitle:hover {
background-color: #447755;
}
/* menu title widths */
#t1 { width: 104px; }
#t2 { width: 100px; }
#t3 { width: 102px; }
#t4 { width: 102px; }
#t5 { width: 180px; }
/* We just specify a fixed width for each menu title. Then, down below we specify
a fixed left position for the corresponding submenus (e.g. #products_submenu, etc.)
Using these fixed values isn't as elegant as just letting the text of each
menu title determine the width of the menu titles and position of the submenus,
but we found this hardwired approach resulted in fewer cross-browser/cross-OS
formatting glitches -- and it's pretty easy to adjust these title widths and the
corresponding submenu 'left' positions below, just by eyeballing them whenever
we need to change the navbar menu titles (which isn't often). */
.submenu {
position:absolute;
z-index: 2;
top: 23px; /* corresponds to line-height of a.navbartitle above */
padding: 0; margin: 0;
width:166px; /* If adjust this, then adjust width of .submenu below a too */
color: white;
background-color:  #666633;
border: 1px solid #447755; /* box around entire sub-menu */
font-family: Verdana, Arial, Geneva,  Helvetica, sans-serif;
font-size: 11px;
}
/* Fix IE formatting quirks. */
* html .submenu { width: 148px; } /* IE needs narrower than width of .submenu above */
/* End */
/* position of each sub menu */
/* We just eyeball the position of each submenu here -- can move left or right as needed.
If you adjust menu title text, you might want to adjust these too. */
#products_submenu {  left: 0px; visibility: hidden;  }
#services_submenu {  left: 104px; visibility: hidden;  }
#funstuff_submenu {  left: 204px; visibility: hidden; }
#aboutus_submenu {  left: 306px; visibility: hidden; }
#contact_submenu { left: 408px; visibility: hidden; }
/* Note, each submenu is hidden when the page loads - then made visible when
the mouse goes over the menu title. Using the 'visibility' property instead
of using the 'display' property avoided a bug in some versions of Safari.
(The bug is pretty where esoteric: The browser ignored the 'hover' property
on 'li' objects inside an object whose display property was set to 'none'
when the page loaded...) Using the 'visibility' property instead of 'display'
would normaly take up extra room on the page, but that's avoided here by putting
the submenu on a second layer: see 'position: absolute' and 'z-index: 2'
in .submenu definition, higher up this page. */

Veuillez pousser votre code meilleure compréhension
Je ne pense pas que vous aurez tous les éléments de pages pour cacher sélectionnez le menu déroulant.
Ne pas décrire, ce que vous avez essayé. SHOW nous, ce que vous avez essayé. I. e. nous montrer un lien. Post code jsfiddle ou
J'ai modifier la question.Maintenant, le scénario est d'essayer de sélectionner toute option et en même temps, passez la souris sur les éléments du menu.
Avez-vous des suggestions?
