Crossword Genius

Display with seals clapping should follow these (4-8)

Ross

I believe the answer is:

show stoppers

'clapping should follow these' is the definition.

'display with seals' is the subsidiary indication.
'display' becomes 'show' ('show' can be a synonym of 'display').
'with' is a charade indicator (letters next to each other).
'seals' becomes 'stoppers'.
'show'+'stoppers'='showstoppers'
