Layout options -> Results Layout -> Results layout position
Hovering - will hover over the content just underneath the search box, same width as the search box
Blocking - depending wether the results shortcode is on the current page, it will show the results in a blocking way, meaining it pushes down the content (if any available)
If the results shortcode is used, the results position is automatically set to Blocking.
Because the results container width can be different from the search bar width, the results have to snap to the search bar to a certain position. With this option you can control this snapping postion.
