Home text editor stripping out html code

[Ckay]

For some reason the Home text editor in my Prestashop version is stripping out html code. The 'HTML purifier' is set to off.

 

Below is the code, which works fine in a standalone html page - I found it in a codepen. The code that is being stripped out is shown in blue.

 

<div class="ipanels">
  <a href="#" class="ipanel">
    <div class="ipanel__content"></div>
  </a>
  <a href="#" class="ipanel">
    <div class="ipanel__content"></div>
  </a>
  <a href="#" class="ipanel">
    <div class="ipanel__content"></div>
  </a>
  <a href="#" class="ipanel">
    <div class="ipanel__content"></div>
  </a>
  <a href="#" class="ipanel">
    <div class="ipanel__content"></div>
  </a>
</div>

 

 

**Edit. This is what the code looks like after I've click 'ok' on the source code button.

 

<div class="ipanels">
<div class="ipanel__content"></div>
<div class="ipanel__content"></div>
<div class="ipanel__content"></div>
<div class="ipanel__content"></div>
<div class="ipanel__content"></div>
</div>

 

What the hell is happening?

 

Anyone any ideas?

 

Thanks in advance.
