Just wondering if the following are still available.
I can’t find Relative size, Absolute size, Fit contents, or Fill container anywhere.
Or maybe I’m missing something I’m expected to know.
These are still available based on a project I just looked at.
These are all options for determining the height and width of a component, you should see them in the properties panel for each component.
If you’re not, could you share a screenshot and the URL of the project?
