Is there any built-in control like a dropdown/slider? For instance, I want to display some info on dialog/control/form and inside that form there is a arrow which expands it to show more information?

When I click the black arrow, the form should expand vertically to show more info. That’s what I want to achieve. If there isn’t any built-in control, can you please tell me what do I need to do to implement it myself? And how can I add a little animation when it is expanding?
Like here (when you click the menu header it doesn’t expand/contract instantly rather it does little slowly, that’s the kind of animation I would like to add)
