Hybrid control
Hybrid control is a functionality where the user is able to select a value from the drop-down list by entering the description or ID/number. This is applicable for the Event enrollment object - Floating limit and Command failure event types; and Scheduler objects.
See Configuring list of object property references within a scheduler object and Configuring event enrollment objects.
Case 1: Enter the description
Taking an example from scheduler object configuration.

This is applicable only for Floating limit and Command failure event types; and scheduler reference object type.

Case 2: Enter the ID/number
