(based on ffc which hasn't been ported to D8).
Allows you to configure field display based on value. Adds a 'Conditions' pane to the cog in Manager Display of all entities (so content types but also comment types, e.g. if you have comments with multiple fields)
Requires Display Suite (ds)
Note: if you wanted to hide say a checkbox when it's value is false - you can do in it core with Manage Display - turn the label off then set (via cog wheel) the output format to Custom, and you can enter a value for true and leave false blank - exactly the same widget for boolean values you use when setting the output of a field in a view.
