Flowrabbit comes with a rich selection of functional components. You can open the component library by pressing W or selecting the icon on the left side of the topbar. To quickly add some of the most common components, you can also use the R (Rectangle), T (Text), or H (Hotspot) shortcuts.
To select a component, simply click on it. The property panel will show up, and you can configure the visual appearance of the component. In addition, you can configure certain properties, for instance, the entries in a dropdown box.
You can also create custom components, learn more about them here!
