Description
You can use if, elseif and else directives to conditionally skip a section of the template. The condition-s must evaluate to a boolean value, or else an error will abort template processing. The elseif-s and else-s must occur inside if (that is, between the if start-tag and end-tag). The if can contain any number of elseif-s (including 0) and at the end optionally one else. Examples:
if with 0 elseif and no else:

Note
How to test if x is greater than 1? <#if x > 1> will be wrong, as FreeMarker will interpret the first > as the end of the tag. Thus, either write <#if (x > 1)> or <#if x > 1>.
