How to display button in tooltip

Question

I have a tooltip in my project. What I like to do is add active button to my tooltip. Problem is that the tooltip is displaying a HTML tags not a button...

Here is the effect of my work:-) enter image description here

Bellow is my code.

Please if some one can help. Thank You.

/* Frame */

.frame {
  height: 150px;
  max-width: 1170px;
  /*line-height: 130px;*/
/*  overflow:visible !important;*/
}

.frame ul {
  list-style: none;
  margin: 0;
  padding: 0;
  height: 100%;
  font-size: 14px;

}

.frame ul li {
  float: left;
  width: 232px;
  height: 100%;
  margin: 0 2px 0 0;
  padding: 0;
  background: #f1f1f1;
  color: #00b5f6;

Answer 1

You can do this without using Javascript. Remove that li and do something like this in a simple way:

.box{
	width: 200px;
	height: 100px;
	position: relative;
	background-color: silver;
	text-align: center;
}
	
.box:hover .tip{
	display: block;
}
	
.tip{
	display: none;
	background-color: yellow;
	position: absolute;
	top: 0;
	bottom: 0;
	left: 0;
	right: 0;
}

<div class="box">

	<div class="tip">
		This is tip content and this is <button>button</button> in it
	</div>

	Box content

</div>

UPDATE

from the link that you provided on your comment (uw.edu.pl) This is what you are trying to do:

ul{
		list-style: none;
	}

	ul.main{
		display: inline-block;
		margin-top: 50px;
	}

	ul.main>li{
		width: 200px;
		height: auto;
		position: relative;
		background-color: silver;
		text-align: center;
	}
	
	ul li ul{
		display: none;
	}
	
	ul li a{
		display: block;
		height: 100%;
        text-decoration: none;
        color: white;
	}
	
	ul li:hover ul{
		display: block;
	}
	
	ul.tip{
		display: none;
		background-color: yellow;
		position: absolute;
		bottom: 100%;
		padding: 0;
		
		height: auto;
		left: 0;
		right: 0;
		z-index: 1;
	}

<ul class="main">
	
		<li>
		
			<a href="#">Box content 1</a>
			
			<ul class="tip">
				<li>
					This is tip content and this is <button>button1</button> in it
				</li>
			</ul>
		</li><li>
		
			<a href="#">Box content 2</a>
			
			<ul class="tip">
				<li>
					This is tip content and this is <button>button2</button> in it
				</li>
			</ul>
		
		</li><li>
		
			<a href="#">Box content 3</a>
			
			<ul class="tip">
				<li>
					This is tip content and this is <button>button3</button> in it
				</li>
			</ul>
		
		</li><li>
		
			<a href="#">Box content 4</a>
			
			<ul class="tip">
				<li>
					This is tip content and this is <button>button4</button> in it
				</li>
			</ul>
		
		</li>
		
	
	</ul>

Answer 2

That li is not need, just change it to div

Also why not just add a hidden div block as tooltip container, on hover show it (just like the tooltip):

.expand:hover>div {
  display: none;
  height: 148px;
  width: 232px;
}

.mytitle {
  display: none;
}

.expand:hover>.mytitle {
  display: block;
  background: red;
}

/* Frame */

.frame {
  height: 150px;
  max-width: 1170px;
  /*line-height: 130px;*/
  /*  overflow:visible !important;*/
}

.frame ul {
  list-style: none;
  margin: 0;
  padding: 0;
  height: 100%;
  font-size: 14px;
}

.frame ul li {
  float: left;
  width: 232px;
  height: 100%;
  margin: 0 2px 0 0;
  padding: 0;
  background: #f1f1f1;
  color: #00b5f6;
  text-align: center;
  cursor: default;
  display: flex;
}

.frame ul li:hover {
  color: #fff;
  background: #00b5f6;
}
