How to keep optionset dropdown closed when setting focus on it in crm365

Hi all,

I have a Salutation field that is optionset when i try to focus on it through below code Xrm.Page.getControl("new_salutation").setFocus(true);

It expands the Optionset and shows all the values. I do not want this to be expanded.

Is there any supported way to be able to focus on a picklist and keep it collapsed?

Thanks in advance,
