Hello @SAP/ui5-webcomponents-topic-p ,

The expectation is for the ui5-select to not close the listbox once a selection in the list is made via SPACE or ENTER.
The same behavior is as so with the openui5 select control: https://ui5.sap.com/#/entity/sap.m.Select
and it is specified that ENTER or "SPACE" keyboard keys would perform a selection and then close the listbox popover.

The change event is also preventable, but the default action is to select an item so the listbox popover is still closed.
Is there a way to prevent the closing of the listbox popover?

Best regards,
Boyan

Hi @InfiniteXyy ,
closing the Select Popover, after making a selection through keypress of "ENTER" or "SPACE" key is the desired behaviour of ui5-select web component and it is as defined by our Accessibility specification. There are no planned enhancements on it in our agenda.

Best regards,
Petya Markova.
