first of all, I'm sorry for my poor english

I want to know add button or A tag in ui-collapsible header??

Hi,

The ripple animation intercepts all clicks on the header. If you disable the ripple, you can add interactive elements to the header, like a link or button.

See this example: https://codepen.io/JosephusPaye/pen/GRoaqKG?editors=1000
