How to add tooltip in a system configuration field.

Hello Friends!!!

In this blog, we are going to learn how we can add tooltips in a system configuration field.

For example, we have to create an input field and we want to add a tooltip with this field, then we can add our tip in <tooltip> tag in the system.xml file as follows:

<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="../../../Config/etc/system_file.xsd">
    <system>
        <tab id="webkul" translate="label" sortOrder="10">
            <label>Webkul</label>
        </tab>
        <section id="custommodule" translate="label" sortOrder="10" showInDefault="1" showInWebsite="1" showInStore="1">
            <label>Custom Module Configuration</label>
            <tab>webkul</tab>
            <resource>Webkul_Custommodule::config_custommodule</resource>
            <group id="general" translate="label" sortOrder="10" showInDefault="1" showInWebsite="1" showInStore="1">
                <label>General Settings</label>
                <field id="customfield" translate="label" type="text" sortOrder="10" showInDefault="1" showInWebsite="1" showInStore="1">
                    <label>Aadhaar Number</label>
                    <validate>required-entry validate-sixteen-degit</validate>
                    <tooltip>It is unique Identification number</tooltip>
                </field>
            </group>
        </section>
    </system>
</config>

See the result in following image:
