Hoverable menu goes out of page - html

Question

I have a hoverable menu as you can see in the code. However, I got a problem when I hover, which the hover content goes out of the page. When I use "position: relative" for the div(content) it is okay but then the text "Example" goes to the left, wonder how to fix.
When I use position: absolute:
When I use position: relative:
ul {
float: right;
position: relative;
}
div {
display: none;
background-color: red;
position: relative;
width: 200px;
}
ul:hover div {
display: block;
}
<ul>
<li>Example</li>
<div>
<ol>
<li>Link 1</li>
<li>Link 2</li>
</ol>
</div>
</ul>

Answer 1

due to lack of space u'r getting this issue make width:200px; for ul
ul {
float: right;
position: relative;
width: 200px;
}
div {
display: none;
background-color: red;
position: relative;
width: 200px;
}
ul:hover div {
display: block;
}
<ul>
<li>Example</li>
<div>
<ol>
<li>Link 1</li>
<li>Link 2</li>
</ol>
</div>
</ul>

Answer 2

You could use position absolute, and manipulate its positions setting a negative margin...
ul {
float: right;
position: relative;
}
div {
display: none;
background-color: red;
position: absolute;
width: auto;
margin-left: -26px;
}
ul:hover div {
display: block;
}
<ul>
<li>Example</li>
<div>
<ol>
<li>Link 1</li>
<li>Link 2</li>
</ol>
</div>
</ul>

Answer 3

Erase the div, apply the width to the ul and apply the display: none and hovering to the ol.
ul {
float: right;
width: 200px;
}
ol {
display: none;
background-color: red;
}
ul:hover ol {
display: block;
}
<ul>
<li>Example</li>
<ol>
<li>Link 1</li>
<li>Link 2</li>
</ol>
</ul>
Second version: If you want everything to be floated right, apply float: right; to ul and li in the HTML structure as used before:
ul {
float: right;
}
ol {
display: none;
background-color: red;
}
li {
float: right;
clear: right;
}
ul:hover ol {
display: block;
}
<ul>
<li>Example</li>
<ol>
<li>Link 1</li>
<li>Link 2</li>
</ol>
</ul>

Answer 4

It's natural behavior, it will depend on header text lenght, it will set your max lenght for below text, you'll need to define a fixed width for the header element and not on child one as you did.
Example of dynamic width (natural div property as a flex container):
ul {
float: right;
position: relative;
}
div {
display: none;
background-color: red;
position: relative;
}
ul:hover div {
display: block;
}
<ul>
<li>ExampleOfMagicMenu</li>
<div>
<ol>
<li>Link 1</li>
<li>Link 2</li>
</ol>
</div>
</ul>
Second example, setting fixed width to the parent box, letting child/s element/s with auto-width (they will never occupy more width than parent, as they can grow in height, overriding height auto with a fixed one will cause overflow):
ul {
float: right;
position: relative;
width: 100px;
text-align: right;
list-style: none;
}
div {
display: none;
background-color: red;
position: relative;
}
ul:hover div {
display: block;
}
<ul>
<li>Example</li>
<div>
<ol>
<li>Link 1</li>
<li>Link 2</li>
</ol>
</div>
</ul>

Answer 5

You can do it with the Flexbox without unnecessary floats and positioning.
Solution with the container as you wrote in the comment:
.container {
max-width: 960px;
margin: 0 auto;
border: 1px solid;
}
ul {
display: flex; /* displays children inline by default that's why you need to change its direction */
flex-direction: column; /* stacks children vertically */
align-items: flex-end; /* places them far right */
}
ul > div { /* modified for accuracy */
display: none;
background-color: red;
width: 200px;
}
ul li:hover + div { /* modified for accuracy since the inner div is the next element after the li */
display: block;
}
li + div:hover {display:block} /* needs to be in order to be displayed when hovering over */
<div class="container">
<ul>
<li>Example</li>
<div>
<ol>
<li>Link 1</li>
<li>Link 2</li>
</ol>
</div>
</ul>
</div>
If you don't fancy the above solution then you can simply add right: 0 to the absolutely positioned div:
.container {
max-width: 960px;
margin: 0 auto;
border: 1px solid;
}
.container:after {
content: "";
display: block;
clear: both;
}
ul {
float: right;
position: relative;
}
ul > div {
display: none;
background-color: red;
position: absolute;
right: 0; /* added */
width: 200px;
}
ul:hover div {
display: block;
}
<div class="container">
<ul>
<li>Example</li>
<div>
<ol>
<li>Link 1</li>
<li>Link 2</li>
</ol>
</div>
</ul>
</div>
