I am using Magento 2.4.5 and I am trying to create a store configuration. The following code works fine, and the tab appears in the backend:
<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:module:Magento_Config:etc/system_file.xsd">
<system>
<tab id="mageplaza" translate="label" sortOrder="200">
<label>Mageplaza</label>
</tab>
<section id="helloworld" translate="label" sortOrder="130" showInDefault="1" showInWebsite="1" showInStore="1">
<class>separator-top</class>
<label>Hello World</label>
<tab>mageplaza</tab>
<group id="general" translate="label" type="text" sortOrder="10" showInDefault="1" showInWebsite="0" showInStore="0">
<label>General Configuration</label>
<field id="enable" translate="label" type="select" sortOrder="1" showInDefault="1" showInWebsite="0" showInStore="0">
<label>Module Enable</label>
<source_model>MagentoConfigModelConfigSourceYesno</source_model>
</field>
<field id="display_text" translate="label" type="text" sortOrder="1" showInDefault="1" showInWebsite="0" showInStore="0">
<label>Display Text</label>
<comment>This text will display on the frontend.</comment>
</field>
</group>
</section>
</system>
</config>
However, when I remove the section and field elements to understand the configuration flow, the backend does not show any tabs, as seen below:
<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:module:Magento_Config:etc/system_file.xsd">
<system>
<tab id="mageplaza" translate="label" sortOrder="200">
<label>Mageplaza</label>
</tab>
</system>
</config>
Can anyone explain the difference and why the tab doesn’t show in the Magento backend without any fields?
