Can't move header blue block to container


I don't understand why I can't move Header Blue block to new container. Here is screen record:


Simple. Blocks cannot be placed inside containers. Blocks are not actually a part of official Bootstrap, but rather a special component unique to Bootstrap Studio. Just expand the Block in the overview, select all the components inside it, and drag them into your container (unless the block already contains a container, in which case you can just drag the container out of the block, and delete the Block component.)
