#  Node-RED Editor Palette

The Palette is the left sidebar that contains all available nodes, including core nodes and third-party nodes that are installed.

#  Search Bar

Located at the top of the Palette, the search bar allows you to quickly find nodes by their name.

#  Node Categories

The palette is divided into several categories, each containing collections of nodes. When you install a third-party node, it may create a new category. Subflows are categorized under "Subflows".

You can collapse or expand categories by clicking on the specific category.

#  Collapse All Categories

At the bottom of the palette, you'll find two arrow icons. Clicking on the first up arrow icon will collapse all categories.

#  Expand All Categories

Clicking on the down arrow icon will expand all categories back as default.

#  Toggle Palette

Clicking this button hides the palette sidebar. To show it again, click on the button once more.
