Hi Bilal,
The free version only supports option panel for Pages. However, this is fairly possible in pro version. Check demo: https://www.slickpopup.com to browse other features that may interest.
But, my friend, there is a filter that you can use in your themes functions file or any site-specific plugin:
Filter Name: splite_dollar_show
Variable to control: $show
– it controls if the popup should be output on that page or post type.
`
add_filter(‘splite_dollar_show’, ‘control_splite_dollar_show’);
function control_splite_dollar_show($show) {
if(‘post’==get_post_type())
return true;
}
`
Let me know if it worked for you. Thanks for using the plugin.
