You have two options. You can hide the definitions on the page while still allowing them to appear when someone clicks a label, or you can remove the definitions completely from the page. Both are controlled by simply setting a variable in the KJESiteSpecific.js file.

To hide the definitions but still allow context sensitive help, include the line below to set the ShowDefinitions variable (the default if this line is missing is true): 
KJE.ShowDefinitions = false;

To not include the definitions definitions on the page or in the context sensitive help set the IncludeDefinitions variable (the default if this line is missing is true): 
KJE.IncludeDefinitions = false;
