jQuery menu dropdown bubbles

So I have this menu that needs to display a box when any item is hovered over. The box is a div that contains heading text and image, here is my code. I'm trying to write a function that will toggle different box on item hover.

For example, hover over 'button 1' and it should toggle '#tab1', hover over 'button 3' toggle '#tab3'.

Class dropdown content has display: none to hide all the divs.

Please any help is appreciated!

$('#secondary-menu li').hover(function(){ 
  var arr= ['1','2','3','4','5'];
  $.each($(this),function(index,value){
    //I don't know what to insert here
    $('#tab'+ [arr]).toggle();
  });
});

$('#secondary-menu li').onmouseout(function(){
  $('#tab' + [arr]).hide();
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<pre>
  <code>
    <div id="secondary-menu">
      <ul>
        <li>button 1</li>
        <li>button 2</li>
        <li>button 3</li>
        <li>button 4</li>
        <li>button 5</li>
      </ul>
    </div>

    <div id="tab1" class='dropdown-content'>
      <h5>Some Heading</h5>
      <img src="">
      <p>Lorem ipsum dolor sit amet, consectetur adipiscing elit. Cras sollicitudin non nisl eget luctus. Vivamus consectetur consectetur orci.</p>
    </div>

    <div id="tab2" class='dropdown-content'>
      <h5>Heading Two</h5>
      <img src="">
      <p>Lorem ipsum dolor sit amet, consectetur adipiscing elit. Cras sollicitudin non nisl eget luctus. Vivamus consectetur consectetur orci.</p>
    </div>
  
    <div id="tab3" class='dropdown-content'>
      <h5>Heading Three</h5>
      <img src="">
      <p>Lorem ipsum dolor sit amet, consectetur adipiscing elit. Cras sollicitudin non nisl eget luctus. Vivamus consectetur consectetur orci.</p>
    </div>

    <div id="tab4" class='dropdown-content'>

      <img src="">
      <p>Lorem ipsum dolor sit amet, consectetur adipiscing elit. Cras sollicitudin non nisl eget luctus. Vivamus consectetur consectetur orci.</p>

$('#secondary-menu li').mouseenter(function(){ 
  $('#' + $(this).data('tab')).slideDown();
}).mouseleave(function(){
  $('#' + $(this).data('tab')).slideUp();
});

.dropdown-content {
  display: none;
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="secondary-menu">
  <ul>
    <li data-tab="tab1">button 1</li>
    <li data-tab="tab2">button 2</li>
    <li data-tab="tab3">button 3</li>
    <li data-tab="tab4">button 4</li>

I've used mouseenter & mouseleave jQuery method along with slideUp & slideDown to provide some kind og animation.

Updated answer without data-tab or data-id Here you go with a solution https://jsfiddle.net/vh7rajh6/1/

$('#secondary-menu li').mouseenter(function(){ 
  $('#tab' + ($(this).index()+1)).slideDown();
}).mouseleave(function(){
  $('#tab' + ($(this).index()+1)).slideUp();
});

.dropdown-content {
  display: none;
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="secondary-menu">
  <ul>
    <li>button 1</li>
    <li>button 2</li>
    <li>button 3</li>
    <li>button 4</li>
    <li>button 5</li>
  </ul>
</div>

<div id="tab1" class='dropdown-content'>
  <h5>Heading One</h5>
  <img src="">
  <p>Lorem ipsum dolor sit amet, consectetur adipiscing elit. Cras sollicitudin non nisl eget luctus. Vivamus consectetur consectetur orci.</p>
</div>

<div id="tab2" class='dropdown-content'>
  <h5>Heading Two</h5>
  <img src="">
  <p>Lorem ipsum dolor sit amet, consectetur adipiscing elit. Cras sollicitudin non nisl eget luctus. Vivamus consectetur consectetur orci.</p>
</div>

<div id="tab3" class='dropdown-content'>
  <h5>Heading Three</h5>
  <img src="">
  <p>Lorem ipsum dolor sit amet, consectetur adipiscing elit. Cras sollicitudin non nisl eget luctus. Vivamus consectetur consectetur orci.</p>
</div>

<div id="tab4" class='dropdown-content'>
  <h5>Heading Four</h5>
  <img src="">
  <p>Lorem ipsum dolor sit amet, consectetur adipiscing elit. Cras sollicitudin non nisl eget luctus. Vivamus consectetur consectetur orci.</p>
</div>

<div id="tab5" class='dropdown-content'>
  <h5>Heading Five</h5>
  <img src="">
  <p>Lorem ipsum dolor sit amet, consectetur adipiscing elit. Cras sollicitudin non nisl eget luctus. Vivamus consectetur consectetur orci.</p>
</div>
