TabFormat

First, you need to have plugins on the server: Some plugin for permissions, like (PermissionsEx , LuckPerms, UltraPermissions, etc..), ServerControlReloaded and TheAPI.

This tutorial will be done in the manner of the LuckPerms plugin ...

setup via /tab - not work, because tab command isn't finished

1. You need to create a group in your permissions plugin, /lp creategroup <groupname>, example: /lp creategroup owner
2. Then in the SCR plugin, you create a tab format /tab create <groupname> , the group you are creating must match the group you created in your permissions plugin.
3. Now you can setup prefix or suffix
4. The prefix appears before the name in the tab and above the player: /tab prefix <groupname> <value>. For example: /tab prefix owner Owner
5. The suffix appears behind the name in the tab and above the player: /tab suffix <groupname> <value>. For example: /tab prefix owner BestOwner
6. Now you need to set the groups priority in the tab: /tab priorite <groupname> <value>. Priority can be from A to Z and from a to z ('A' is the highest priority, 'z' is the lowest priority). For example: /tab priorite owner A

All available commands: /tab
