Yes, using a filter on your userlist. Please see the below example.
Display only if subscribed:
Code:
( ( SELECT COUNT(*) FROM `#__cbsubs_subscriptions` AS subs WHERE subs.`user_id` = ue.`id` AND subs.`plan_id` = PLAN_ID_HERE AND subs.`status` = 'A' ) > 0 )
Display only if NOT subscribed:
Code:
( ( SELECT COUNT(*) FROM `#__cbsubs_subscriptions` AS subs WHERE subs.`user_id` = ue.`id` AND subs.`plan_id` = PLAN_ID_HERE AND subs.`status` = 'A' ) = 0 )
With the above replace PLAN_ID_HERE with the actual plans ID you want to filter by.
