No Slider button

Anyone else getting this? there’s no button on my sliders when i use the menu. they don’t even take up space where they should’ve been

Are you creating an EditorWindow or are you using the runtime preview components? If you are at runtime, this might be caused by a missing default style sheet on the panelRenderer component.

got my default style sheet
im using the runtime preview component

ListView is a data container that must be populated by code. In your case, you need a ScrollView. This usage will be fixed in 2020.2

ah ok, thanks
