flexy:nameuses="variable" -- Use a variable in the name for a flexy form element
Описание
If you have a form with multiple input boxes (eg. group members), which are dynamically generated,
then this attribute can be used to generate flexy elements based on sprintf'ing the variable value
into the name attribute value.
