Component should only have one label #11
Description
Feature proposal
Taking a look at the current implementation, the component has a global label ("custom default set" in the attached image), then the options' combobox has no label but the text field has one ("Cron expression"). This is not standard. The component as a whole should have a label, as for example Date Time Picker in Vaadin components.
Describe solution expectations
A single label for the component.
