你必须在你的 system.xml 中配置它：

...
<sections>
    <catalog>
        <groups>
            <frontend>
                <fields>
                    <dropdown translate="label comment">
                        <label>Dropdown</label>
                        <comment>Dropdown with global scope.</comment>
                        <frontend_type>select</frontend_type>
                        <source_model>jr_customconfigexample/system_config_source_dropdown_values</source_model>
                        <sort_order>30</sort_order>
                        <show_in_default>1</show_in_default>
                        <show_in_website>0</show_in_website>
                        <show_in_store>0</show_in_store>
                    </dropdown>
