How to edit your slider from admin panel in WordPress?

Good time of day.
There is a slider. Used Slick.
The Html is:
<div class="your-class">
 the <div>your content</div>
 the <div>your content</div>
 the <div>your content</div>

How to implement adding a new div and its internal elements through the admin panel?
All settings have always used the Options Framework, but there is no ajax add a new item.
What I would like ideally: have created the fields that appear in the slider, brought.
When you need a new slide, click "Add" - creates a duplicate of the slide and displays.
