Items in custom dropdown menu not working properly in Yii 2

Question

I'm creating my own dropdown list function in Yii2. I have created a function and a view and in the view I have multiple items in my dropdown form. <?=$form->customDropDown($dpForm,'color',['items'=>['label'=>'red','value'=>'red','options'=>['style' =>'color:red']]['label'=&g

To achieve the desired output, where each item in the dropdown is represented by a single tag with the specified label, value, and style, you need to modify your code as follows: In your view file, update the customDropDown function call to correctly pass the items array:

customDropDown($dpForm, 'color', [
        [
            'label' => 'red',
            'value' => 'red',
            'options' => [
                'style' => 'color: red'
            ]
        ],
        [
            'label' => 'blue',
            'value' => 'blue',
            'options' => [
                'style' => 'color: blue'
            ]
        ],
    ]
); ?>

Updated method:

public function customDropdown($model, $attribute, $items = [], $options = [])
{
    $value = Html::getAttributeValue($model, $attribute);

    $field = $this->field($model, $attribute);

    $options['options'] = array_column($items, 'options');
    $options['prompt'] = '';

    return $this->staticOnly ? $field : $field->dropDownList(array_column($items, 'label', 'value'), $options);
}

In this updated version, we pass the $options array directly to the dropDownList method and use array_column to extract the label-value pairs from the $items array
