• Emipro Technologies Pvt. Ltd.: I think you need to add attribute options with store code.
• anonymous: @EmiproTechnologiesPvt.Ltd.,Can you please elaborate in more detail ?
• Emipro Technologies Pvt. Ltd.: We think there is some store related issue you faced. Please check table screenshot: nimb.ws/yGlMDW and check your table.
• anonymous: I dont think its causing issues, cause i checked my DB and i am running with Sample data and all sample attributes options has store_id = 0.

Answer 1

Please do following suggestions in the install script.

Make 'user_defined' => true from 'user_defined' => false

In case the above solution didn't work, then remove the backend and source attributes. i.e,

• 'backend' => 'Magento\Eav\Model\Entity\Attribute\Backend\ArrayBackend'
• 'source' => 'Vendor\Module\Model\Brands\Values'

• Jafar Pinjar: hi @Amit, can we create the attribute without installer?
