The Library Browser contains all the components required to build models. Blocks are dragged and dropped from the respective libraries to the work area, then connected, and adjustments are made to parameters.
Multiple blocks can be selected and dragged to the canvas by using the SHIFT key or CTRL key and clicking the desired blocks.
The search feature allows easy navigation of the library browser. By searching in the input, one can narrow done the blocks to find the desired block easily. Once the block is found, simply drag and drop to place.
Information regarding each block can be obtained by hovering over the small I icon that appears when hovering over a block. Text appears that summarizes the block.
To see how the various components are distributed between the grouped menus, see The Block Library by Class & Component.
