In this post I am going to explain how to add tooltip in ui_component form field in Magento 2.

Check the below example code snippet to add tooltip in ui_component form field.

<field name="identifier" formElement="hidden">
    <argument name="data" xsi:type="array">
        <item name="config" xsi:type="array">
            <item name="dataType" xsi:type="string">text</item>
            <item name="label" xsi:type="string" translate="true">Identifier</item>
            <item name="formElement" xsi:type="string">input</item>
            <item name="source" xsi:type="string">identifier</item>
            <item name="dataScope" xsi:type="string">identifier</item>
        </item>
    </argument>
    <settings>
        <dataType>text</dataType>
        <tooltip>
            <link>https://www.google.com</link>
            <description translate="true">Tool-tip content for the identiier field.</description>
        </tooltip>
    </settings>
</field>

Here under “<settings>” tag “<tooltip>” tag is used to add tooltip.

<link> – Link will redirect to specific page on click of tooltip icon.
<description> – Display text on tooltip icon hover.

Thats it. Enjoy Magento 2!!
