Overwrite magento_theme adminhtml ui_component xml file

Question

I am trying to overwrite following file: vendor/magento/module-theme/view/adminhtml/ui_component/design_config_form.xml

The changes work when editing the file directly in vendor dir, however, I am having some problems overwriting this file.

I copied the file to following location but it just doesn't work: app/code/Magento/Theme/view/adminhtml/ui_component/design_config_form.xml

I ran:

rm -rf generated/code

rm -rf pub/static/* var/view_preprocessed

php bin/magento setup:upgrade

php bin/magento setup:di:compile

php bin/magento cache:clean && php bin/magento cache:flush

Nothing seems to work. What am I doing wrong?

Answer 1

Define This in module.xml

 <sequence>
 <module name="Magento_Theme"/>
 </sequence>

Component load order

• Greg: This seemed to work! Can you explain I had to add this?
• Ronak Rathod: its specify for load order
• Ronak Rathod: devdocs.magento.com/guides/v2.3/extension-dev-guide/build/…
• Greg: Great. Thank you! Lesson learned!
• Ronak Rathod: most welcome happy coding....:)

Answer 2

The file has likely been copied to the wrong location. Your theme is either frontend or adminhtml so does not require that distinction in the folder structure.

So instead of app/code/Magento/Theme/view/adminhtml/ui_component/design_config_form.xml you'll need something like path/to/admin-theme/Magento_Theme/ui_component/design_config_form.xml

Answer 3

You can extend the ui_component using a custom module.

1. So create a Vendor/Module. (registration, etc/module.xml, composer.json)
2. Extend the ui_component in your module. Vendor/Module/view/adminhtml/ui_component/ui_component_name.xml

An official example of extending the category form ui_component can be found here
