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

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

<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>
        <disabled>1</disabled>
    </settings>
</field>

Here under “<settings>” tag “<disabled>1</disabled>” tag is used to make field readonly.

Thats it. Enjoy Magento 2!!
