Moves the vertical position of a block to below the avoid region of an avoided block in stead of being placed beside it during side by side formatting.

You can set up side by side placement of blocks by using <?blockavoidme> and <?blockposreset> commands. Set an avoid setting on the first block then subsequent content will continue aligned with the avoid region until it has passed the margins of the avoid block. Content will then wrap under the avoided block. You can force a subsequent block to start below the avoid block before this limit has been passed if required. Use a <?blockavoidclear=1> command for the relevant block.
