                      ['label'=>'Nike', 'value'=>'1'],
                      ['label'=>'Puma', 'value'=>'2'],
                      ['label'=>'Adidas', 'value'=>'3']
                     ];
    return $this->_options;
}


public function getOptionText($value)
{
    foreach ($this->getAllOptions() as $option) 
    {
        if ($option['value'] == $value) {
            return $option['label'];
        }
    }
    return false;
}


public function getFlatColumns()
{
    $attributeCode = $this->getAttribute()->getAttributeCode();
    return [
        $attributeCode => [
            'unsigned' => false,
            'default' => null,
            'extra' => null,
            'type' => Table::TYPE_INTEGER,
            'nullable' => true,
            'comment' => 'Custom Attribute Options  ' . $attributeCode . ' column',
        ],
    ];
}
}

Please help me with this, What i am missing ??

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'
