HTML/CSS Submenu in block - html

I'm trying to create a submenu in html/css. I already have a piece of code, but i would like to have a submenu in block below each menu item, but i can't figure out how to do it. Anyone would like to help?

Right now, when i hove over a menu item, all the submenu items appear at once, and in inline-block, which is not what i want.

You have two main problems here:
First this selector .mainmenu ul:hover ul it's wrong since is showing all ul elements when you hover the main ul.
Change to this:
.mainmenu li:hover > ul
Making visible just the sub ul element inside a li.
Also those submenus need to be absolute positioned so they don't disturb the layout of the upper menu:
.mainmenu ul li {
position:relative;
}
.mainmenu ul li > ul {
display: none;
position: absolute;
z-index:10;
}
Check this Snippet
.mainmenu ul {
padding:0;
width: 940px;
position: relative;
list-style: none;
font-size: 16px;
color: #000;
}
.mainmenu ul li {
float: left;
text-transform: uppercase;
padding: 0 20px 0 20px;
font-size: 16px;
color: #000;
position:relative;
}
.mainmenu ul li a {
display:block;
text-decoration: none;
padding: 9px 0 9px 0;
font-weight: bold;
font-size: 16px;
color: #292F51;
}
.mainmenu ul li a:hover {
text-decoration: none;
color: #FFF;
background-color: #292F51;
}
.mainmenu ul li > ul {
display: none;
position: absolute;
z-index:10;
}
.mainmenu li:hover > ul {
display: block;
}
<div class="mainmenu">
<ul>
<li class="operador chefe">

</div>

This will work fine.
The most important rule is that when you hover a li it should show its child ul.
.main-menu,
.sub-menu {
font-size: 0px;
margin: 0px;
list-style: none;
padding: 0px;
font-family: 'Helvetica';
}
.sub-menu {
display: none;
}
.menu-item,
.sub-item {
background: navy;
color: white;
font-size: 14px;
text-align: center;
min-width: 80px;
padding: 4px;
}
.menu-item {
display: inline-block;
vertical-align: top;
}
.menu-item:hover,
.sub-item:hover {
background: blue;
}
.menu-item:hover > ul {
display: block;
}
<ul class="main-menu">
<li class="menu-item">Item 1</li>
<li class="menu-item">Item 2 (With sub-items!)
<ul class="sub-menu">
<li class="sub-item">Item 3</li>
<li class="sub-item">Item 4</li>
</ul></li>
<li class="menu-item">Item 5</li>
<li class="menu-item">Item 6 (With sub-items!)
<ul class="sub-menu">
<li class="sub-item">Item 7</li>
<li class="sub-item">Item 8</li>
</ul></li>
</ul>

I don't really like submenu coded from scratch (from zero). You can today create some menu "without" any CSS.
You can use Bootstrap class to realize menu like that:
http://jsfiddle.net/fm571dsd/4/
html:
<body>
<div class="container">
<div class="row">
<nav class="navbar navbar-default">
<div class="navbar-header">
<button type="button" class="navbar-toggle" data-toggle="collapse" data-target="#myNavbar">
<span class="icon-bar"></span>
<span class="icon-bar"></span>
<span class="icon-bar"></span>
</button>
<a class="navbar-brand" href="#" target="_blank">Logo</a>
</div>
<div class="collapse navbar-collapse" id="myNavbar">
<ul class="nav navbar-nav">
<li class="dropdown">
operador chefe
<ul class="dropdown-menu">
<li>item 1</li>
<li>item 2</li>
<li>item 3</li>
</ul>
</li>
<li class="dropdown">
safety
<ul class="dropdown-menu">
<li>item 1</li>
<li>item 2</li>
<li>item 3</li>
</ul>
</li>
<li class="dropdown">
security
<ul class="dropdown-menu">
<li>item 1</li>
<li>item 2</li>
<li>item 3</li>
</ul>
</li>
<li class="dropdown">
atendimento
<ul class="dropdown-menu">
<li>item 1</li>
<li>item 2</li>
<li>item 3</li>
</ul>
</li>
<li class="dropdown">
apoio unidades comerciais
<ul class="dropdown-menu">
<li>item 1</li>
<li>item 2</li>
<li>item 3</li>
</ul>
</li>
</ul>
</div>
</nav>
</div>
</div>
</body>
js:
(function($){
$(document).ready(function(){
$('ul.dropdown-menu [data-toggle=dropdown]').on('click', function(event) {
event.preventDefault();
event.stopPropagation();
$(this).parent().siblings().removeClass('open');
$(this).parent().toggleClass('open');
});
});
})(jQuery);

couldn't show submenu of horizontal menu on hover

there are navigation panel(div id=#nav) in which is located horizontal menu(nav_main_ul). It has submenu. When I load site main horizontal is appear but on hover submenu of main manu is not appear.
I write:
.nav_main_ul li a:hover .submenu{
top:150;
}
What is wrong?
Everything did work while I use flexbox for sidebar, content and footer.
I'm newbie in html and css. I think reason of failure is conflict between position(absolute, relative) and flexbox.
Thanks in advance.

Edit
Hi Delphi - To answer your question about the + selector, let's take a look at your HTML markup:
<li>
Main
<ul class="submenu">
<li>link 1</li>
<li>link 2</li>
<li>link 3</li>
<li>link 4</li>
</ul>
</li>
We need to understand that in the above markup, we can express it as:
LI (Parent / Root)
- A (Child of LI, Sibling of UL)
- UL (Child of LI, Sibling of A)
- LI (Child of UL, Grand-Child of LI)
Your desired action is that when a user hovers over the A, we show the UL.
USUALLY with CSS, we think of NESTED (or PARENT/CHILD) use-cases. But in YOUR use case, the A and UL are NOT in a parent/child relationship. Rather, they are siblings.
So, what we want is: When a user hovers over the A, we want the SIBLING(s) of A (in this case, only UL) to have TOP: 50PX.
There are TWO sibling selectors in CSS, "Adjacent" and "General". Adjacent means that it will ONLY apply when the siblings are directly together. For example:
<div>
<p></p>
<span></span>
<span></span>
<p></p>
</div>
OR:
DIV
- P
- SPAN
- SPAN
- P
Let's assume in the above, we wanted to select every SPAN that is a SIBLING of P. If we did:
p + span { color : red }
Only the FIRST span would be applied. That's because, it's the only span that immediately is next to a P element. Demo: http://jsfiddle.net/ucq5pg13/
What if we wanted ALL spans following a P to be red? That's where our GENERAL sibling selector comes into play:
p ~ span { color: red }
What this says is that ANY span that's a SIBLING of P, that comes AFTER IT, will be red.
It's important to note that it MUST come after. For example:
p ~ span { color: red }
<div>
<span></span> <!-- I WOULD NOT BE RED -->
<p></p>
<span></span> <!-- I WOULD BE RED -->
<span></span> <!-- I WOULD BE RED -->
<p></p>
</div>
Demo: http://jsfiddle.net/kb7n5236/
Hopefully that helps :)
Original:
When you hover over the a link, you'll need to position the .submenu. You can do something like:
<!-- On hover, show submenu -->
.nav_main_ul li a:hover + .submenu,
.nav_main_ul li a + .submenu:hover {
top: 50px;
}

Toggle dropdown menu on ul:focus

I'm trying to create dropdown navigation with pure CSS and I want to show dropdown menu on ul click. Problem is that simple ul:focus > ul doesn't work even though there is anchor in it. Selectors :hover and :active are working without problems.
HTML
<li>Menu 1
<ul>
<li>Sub Menu 1</li>
<li>Sub Menu 2</li>
<li>Sub Menu 3</li>
<li>Sub Menu 4
</ul>
</li>
CSS
#primary_nav_wrap ul li:hover > ul
{
display:block
}
Here's the code:
https://codepen.io/anon/pen/vgpQWV
Your selector needs to be #primary_nav_wrap ul li > a:focus + ul.
Breaking it down:
When the <a> directly inside the <li> has focus, apply these styles to the immediately adjacent <ul>.
Fixed example:
#primary_nav_wrap {
margin-top: 15px
}
#primary_nav_wrap ul {
list-style: none;
position: relative;
float: left;
margin: 0;
padding: 0
}
#primary_nav_wrap ul a {
display: block;
color: #333;
text-decoration: none;
font-weight: 700;
font-size: 12px;
line-height: 32px;
padding: 0 15px;
font-family: "HelveticaNeue", "Helvetica Neue", Helvetica, Arial, sans-serif
}
#primary_nav_wrap ul li {
position: relative;
float: left;
margin: 0;
padding: 0
}
#primary_nav_wrap ul li.current-menu-item {
background: #ddd
}
#primary_nav_wrap ul li:hover {
background: #f6f6f6
}
#primary_nav_wrap ul ul {
display: none;
position: absolute;
top: 100%;
left: 0;
background: #fff;
padding: 0
}
#primary_nav_wrap ul ul li {
float: none;
width: 200px
}
#primary_nav_wrap ul ul a {
line-height: 120%;
padding: 10px 15px
}
#primary_nav_wrap ul ul ul {
top: 0;
left: 100%
}
#primary_nav_wrap ul li > a:focus + ul {
display: block
}

White-Space: Nowrap float issue

I have what is hopefully a simple problem that I'm just overcomplicating in my mind.
Here is a Fiddle to demonstrate my issue.
In the Fiddle above you will see a flyout menu setup. On the top option you will see an enlarged first option that has a broken float. This is where my issue is. I need those elements to float alongside each other without breaking the list container holding them.
I understand that the white-space:nowrap is causing the break of that containers space, however, whenever I try and remove that element I can't seem to get my float to honor. I'm sure this is a simple miss on my part due to thinking of things that will be surrounding it, but any advancement on this is appreciated and hopefully an easy up for someone.

Remove the float left form the image within float div. And add some margin over there.
CSS:
.sub img {
min-width: 120px;
/* float: left; */ //Remove this line
margin-top: 10px;
}
See this fiddle.
One way to acheive your desired layout is to set inline-block for both the image container, and the container for the headings/sub headings.
vertical-align: top; is necessary to ensure the two containers align at their top edges.
For the sake of simplicity, I kept your existing float class. (Note that this class needed to be added to the container for the heading/sub-heading/specs.)
.float {
display: inline-block;
vertical-align: top;
}
Please check this code , i think you are looking for this, you dont need to set width to .sub i have added new division and add some property
.float , .inline-block {
display:inline-block;
vertical-align:top;
}

I am a very beginner to HTML and CSS. When I'm practicing CSS drop down menus, sub menus are inline and not aligned properly. Let me know the mistake what I have done and rectify the mistake.
#menu{ list-style-type:none; margin:0; padding:0; }
#menu li{ display:inline; }
#menu li a{ text-decoration:none; background-color:#FFAAFF; color:Black; display:inline-block; padding: 20px 40px; }
#menu li a:hover{ background-color:#AA7FFF; color:White; }
.submenu{ display:none;position:absolute; top:66px; margin:0; padding:0; }
.submenu li a{ display:inline-block; }
#menu li:hover .submenu{ display:inline-block; }

Can't change background colour of navigation bar

I can't change the colour of the background that my navigation bar has. I'm not using any framework so there's no conflicts. Here's the code that I have tried:
.navigation-right {
float: right;
}
.navigation-left {
float: left;
}
.navigation-main {
background-color: #000;
width: 100%;
}
.navigation-main li {
display: inline-block;
padding: 10px;
}
.navigation-main a {
color: #F2F2F2;
text-decoration: none;
}
<div class="container">
<section class="navigation">
<nav class="navigation-main">
<ul>
<div class="navigation-right">
<li>Menu
</li>
<li>Menu
</li>
<li>Menu
</li>
<li>Menu
</li>
<li>Menu
</li>
</div>
<div class="navigation-left">
<li>Menu
</li>
<li>Menu
</li>
<li>Menu
</li>
<li>Menu
</li>
<li>Menu
</li>
</div>
</ul>
</nav>
</section>
You are missing an overflow:hidden in the parent of the floating elements. Without it, the browser can't calculate the height hence the background colour not coming through. Try adding this line to your CSS:
.navigation-main{
background-color: #000;
width: 100%;
overflow: hidden; // Add this
}
You have to clear your floats. Using overflow is a sneaky, though not always preferable way. The best way - in my opinion - is using a pseudo element, like so:
/* Clear */
ul::after {
content: "";
display: table;
clear: both;
}
.navigation-right {
float: right;
}
.navigation-left {
float: left;
}
.navigation-main {
background-color: #000;
width: 100%;
}
.navigation-main li {
display: inline-block;
padding: 10px;
}
.navigation-main a {
color: #F2F2F2;
text-decoration: none;
}
<div class="container">
<section class="navigation">
<nav class="navigation-main">
<ul>
<div class="navigation-right">
<li>Menu
</li>
<li>Menu
</li>
<li>Menu
</li>
<li>Menu
</li>
<li>Menu
</li>
</div>
<div class="navigation-left">
<li>Menu
</li>
<li>Menu
</li>
<li>Menu
</li>
<li>Menu
</li>
<li>Menu
</li>
</div>
</ul>
</nav>
</section>
Note though, that you oughtn't split up your menu like that, with divs inside a list. Instead, create two seperate lists.
Just corrected your HTML and add overflow:hidden to you're .navigation-main{...}
JsFiddle There
Teknotica had it aswell :)
