how to instantiate ui elements

how do i add and remove new entries to a listview for example?

Hi, assuming that you are on 2019.3 there are UIElements sample available inside the editor which include a small ListView example.

You can find them in the editor menu “Window → UI → UIElements Samples”.

How do you actually open the examples? Going to “Window → UI → UIElements Samples” opens a panel. Then what?

There’s a known bug, the panel needs to have its right edge pulled to the right to reveal the example.
