Restrict assignable user

[RainBow]

Hello

In my project, the user that have assign permission  shouldn't assign any user, any one (have assign permission) must see the special group for assign.

For example:

users A,B, C have assign permission and they can assign issue,

Group D,Group E and Group F  have assignable permission.

In usual condition, user A when assign issue, see all user in Group D, E ,F.

I want user A when assign issue can see ONLY user in Group D.

user B when assign issue can see ONLY user in Group E 

and ...

Is this possible?How do I do it?

Please help me.

Thanks for your Time.

HI @RainBow 

In this case, you need to use the user picker custom field in which you need to add the group filer (group D)in the custom field configuration.

and please this user picker field on the screen ..whenever the user A will start typing the name then only people belong to Group D will be visible.

 Using post function you can copy the user picker field value to the assignee field, for this, u need to check third party plugins like JMWE, JSU etc..

The the list of available assignees listed in the assignee field is determined by the project's permissions. 

It is not determined by who the current user is.  So, no, you can't do this.
