I want to move fields on customer/index/edit. Creating another fieldset can be done with <form xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:module:Magento_Ui:etc/ui_configuration.xsd"> <fieldset name="my-new-fields"> <argument name="data" xsi:type="array"> <item name="config" xsi:type="array"> <item name="label" xsi:type="string" translate="true">Additional Information</item> </item> </argument> <field name="blablupp"> <argument name="data" xsi:type="array"> <item name="config" xsi:type="array"> <item name="label" translate="true" xsi:type="string">buueeyyy</item> <item name="visible" xsi:type="boolean">true</item> <item name="dataType" xsi:type="string">text</item> <item name="formElement" xsi:type="string">input</item> <item name="source" xsi:type="string">customer</item> </item> </argument> </field> </fieldset> </form> And even hiding a field from an existing fieldset is easy by adding to the customer fieldset: <form xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:module:Magento_Ui:etc/ui_configuration.xsd"> <fieldset name="customer"> <argument name="data" xsi:type="array"> <item name="config" xsi:type="array"> <item name="label" xsi:type="string" translate="true">Additional Information</item> </item> </argument> <field name="prefix"> <argument name="data" xsi:type="array"> <item name="config" xsi:type="array"> <item name="visible" xsi:type="boolean">false</item> </argument> </field> </fieldset> </form> But what I really want is to move a field from customer to another to simplify life for unexperienced admin users. How is that accomplished?
