-Conditional hidden family and calculated default value
+A dynamic family
 
-Add a sub family "https_proxy" which will be hidden if "use_for_https" is True.
+HTTPS and socks proxy are very similar. It could be interesting to do on dynamic family instead of duplicate family and variable description.
 
-Hidden means that we cannot change value, but we can access to it in read only mode. Inside, we add two variable with calculated default value (with variable type).
+First of all, we add a dynamic attribute to the family. Dynamic is here a static list of suffix. It could be a variable or jinja informations too.
 
-So, if user set "use_for_https" to True, the default values of HTTPS configuration will be a copy of HTTP values. The use can change HTTPS values if needed.
+The dynamic family is only hidden in the HTTPs case.
+Hidden is now a Jinja calculation with a parameter named "suffix".
 
-If user set "use_for_https" to False, the default values of HTTPS configuration will only be a copy of HTTP values.
+The suffix is use in:
+
+- family name
+- family description
+- variables name
+- variables description
