Add or remove forms for the plugin selector

You're able to provide forms to different user/usergroups, simply by using Page-TypoScript (tsconfig).

Notice:

This configuration is only for the backend form selection. A form can also be defined and used by Setup-TypoScript!

TCEFORM.tt_content.pi_flexform.fluidform_form.sDEF {
    settings\.form {
        removeItems = contactBasic, callBack, jobApplication, fileUpload
    }
}
