Okay so to create the slides for carousel, you need to create a template.
So I created template in elementor. In Elementor you need to add a section to put the text, button and etc. So In section there’s setting in Style the you can put background on it and there’s a dynamic tag where you can set it as Featured Image.
I set the background image to featured image, the preview is working. after finishing this template I added it on the premium carousel, but the background is not showing anymore.
I think it’s not getting the value of dynamic tag when you put it on the carousel. Thanks
