I am trying to develop a module extension which needs to store some settings, I went through the documentation and found this to be the way to create settings.

Now when I put default as NULL the setting is not reflected in the table, if I put any value as default the setting is added to civicrm_setting table.

Also, though the settings have option to specify attributes for admin form, I couldn't figure out a way to get them to the admin form.

Is there anything else which I need to do apart from adding the setting folder and the following code to extension.php

function multisite_civicrm_alterSettingsFolders(&$metaDataFolders = NULL){
     _multisite_civix_civicrm_alterSettingsFolders($metaDataFolders);
}
