 ## Grouping and Layouts
-Now that you know how to place new components it's time to learn another important concept, grouping. This is how you group UI elements together and control the layout of the elements under a group. Use the **Node Picker** to create a new group, place it where you want it in the heirarchy, select, drag and drop the UI elements that you want under the group.
