i have an two different level of variables in the jenkins build page, one for default variables and another one for advanced, so the user need not to fill this advanced variable all the time, once at the specific need he fill those options, otherwise he can go with the default one, on that case, i would like to bring this advanced variables under advanced button on that build page, so whenever user needs to fill advanced variables, on that time he/she click this advance button, then he can fill those desired variables, then trigger the build, otherwise he can trigger the build with default variables, right now Jenkins it's listing all variables in the build page, is that any option or plugin is available to achieve this process.
