Slider change

Hi htashrif52,

Thanks for reaching to us.

If you want to import the main demo slider, try to create a staging site. https://www.wpbeginner.com/wp-tutorials/how-to-create-staging-environment-for-a-wordpress-site/

Import the main demo on the staging site, and you can copy or Import/export the slider template to the live site. or other content types without affecting the live site.

If you have any questions, feel free to contact us.

Regards,
Hung PD
