You can create a custom template file and style it to look like a slider. You can grab one of the default template files which can be found in the plugin’s folder gmw-nearby-location/templates/posts/. You should copy one of the folders “default”,”lightcoral” or “lightseagreen” and place it in your theme’s or child theme’s folder. You should be placed in the theme or child theme folder/geo-my-wp/nearby-locations/posts/ ( you need to create the geo-my-wp folders under the theme’s folder ). This way your changes will not be deleted when you updated the extension.
After having it in the theme’s folder you can style it as you want. I cannot guide you on how to style it to look like a slider as it might require a good amount of work to be done. However, it can be done if you know CSS, HTML and PHP.
