As far as I know, there is nothing to do with shortcode to use that plugin. Have you learn how to use that plugin? Please ask the plugin author if you had any trouble on install & setup that plugin.
Ya, because I just intalled plugin on landing page demo just to show you that those plugin work without any problem on Jkreativ theme. We’re not use any third party plugin other than required plugins on our demo before and will delete those plugin after this.
