Current behavior
currently components like dropdown and autocomplete don't have p-header as a header template.

Expected behavior
It would be very usefull to have header on these components to have be able to add customized template for header like filter buttons or add buttons or ....
Actually we created a custom component now but t would be very nice to have this feature built in.

What is the motivation / use case for changing the behavior?
in the project there is a search box that loads data from different sources and I need to have buttons for filtering them based on source name like(customers/companies)

+++ I need 'Add new' button at the top of dropdown list.

@Serg-Mois I need something similar and had to create a rig for now. Did you come up with an elegant solution for this?

You can attribute this improvement to me, I can develop it.

@aminTiz Would you mind sharing the custom component you created as a workaround for this?
