PS 1.6.1 Category description - show more button

[Holohugo]

Hello,

 

im using PS 1.6.1.13. I wanna have button MORE in category description, that will show more content without the symbol limit. I need the button just to show some extra div with content, like below.

Thanks for any help

 

<div class="ALWAYS-VISIBLE-DESCRIPITON">
content of any length
</div>
<div class="VISIBLE-AFTER-CLICK-ON-MORE-BUTTON">
content of any length
</div>
