Display subpanels in Tasks Module

How do I add subpanels (ie Contacts,Accounts) to the Tasks Module.

Task > Detail View > only displays notes Subpanel

Contacts and Accounts subpanels are set to display system wide:

Admin > Display Modules and SubPanels

Relationships of Tasks to Contacts and Accounts exists.

Admin > Studio > Tasks > Relationships

Version 7.10.7
Sugar Version 6.5.25 (Build 344)

CentOS release 6.10
Server version: Apache/2.2.15 (Unix)
PHP 7.0.3 running as FPM served by nginx version: nginx/1.13.8
mysql Ver 14.14 Distrib 5.1.73, for redhat-linux-gnu (x86_64) using readline 5.1

I think subpanels appear when the relationship is the other way around.

So currently a Contact can have many tasks, so you find a subpanel for Tasks under Contact’s Detail view.

You would need to create a new one-to-many Relationship in the other direction, to make each Task have many Contacts. Is this what you want?

I will try this.

Does it have to be one (task) - to -many (contacts)? Will this work if it is just a one-to-one?

OK nevermind. I see the anwer now:

All of the Relationships that exist between the module and other deployed modules appear here.

The relationship Name is the system-generated name for the relationship.

The Primary Module is the module that owns the relationships. For example, all of the properties of the relationships for which the Accounts module is the primary module are stored in the Accounts database tables.

The Type is the type of relationship exists between the Primary module and the Related Module.

Click a column title to sort by the column.

Click a row in the relationship table to view the properties associated with the relationship.

Click Add Relationship to create a new relationship.

Relationships can be created between any two deployed modules.
