Extend-ability and updates proofing

[ChrisChristou]

Does the SelectManager folder overwritten on updates or is it safe to edit classes there ?

 [B]namespace Espo\Modules\Crm\SelectManagers;[/B]

Is there a way to extend those classes in custom folder like creating this

[B]custom/Espo/Custom/SelectManagers[/B]

folder and extending there?

Hello
It is not safe to modify files in Espo\Modules\Crm\SelectManagers\

You can create a SelectManager for a certain entity in custom namespace (custom/Espo/Custom/SelectManagers/{Entity},php). Inherit it from Espo\Modules\SelectManagers\{Entity} or from Core class if previous doesn't exist. This will an upgrade safe way.
use namespace Espo\Custom\SelectManagers
