Either surround in an if(), such as: 
 if( 
 [boolean expression], 
 a!sailComponent(parameters: ), 
 {} 
 ), 
 or the vastly better showWhen parameter that Appian has so wonderfully been adding to virtually all components. It does the same thing, but far simpler: 
 a!sailComponent( 
 parameter: 
 otherParameter: 
 showWhen: [boolean expression] 
 )
