I have SAPUI5 DynamicPageHeader in Fiori app, which looks like this:

It has a "collapsible" link & one filter bar is selected with value in it.. When I collapse the header, I want to show "Filters Selected:1", something like this:

How can this be achieved? I read through DynamicPageHeader API wiki, but could not find any direct way/methods to do this.

Thanks in Advance.
