The Palette panel displays a list of all functions and variables that can be used in Blueprints. It is fully searchable, contains a Favorites panel that you can populate with the nodes you find yourself using the most, and you can filter it to search for nodes that are compatible with a specific class type. Nodes from the Palette panel can be added into your networks by simply dragging and dropping them from the list.

1. Favorites - This shows your favorite and frequently used nodes. You can add nodes to this area by Right clicking them within the Palette panel and choosing Add to Favorites .

2. Palette list - This is a list of all available functions, filterable by class and searchable.

Class Filtering

Sometimes it is useful to filter down the Palette to only show those nodes that are compatible with a given class type. This is done using the Class Filter dropdown. When clicked, it shows a list of all classes available in your project, similar to the Class Viewer panel. It also contains a search bar that you can use to actively filter down the list.
