Pre Selected Options are not displaying

Hi @pandeyamit,
Can you give some code example of your widget settings?
If your model attribute is a single value, or an array, the widget my set the values by default.

Hello,
thx for quick reply. Here is my code example:

Select Company field($model, 'company_id')->widget(Widget::className(), [ 'options' => [ 'multiple' => true, 'placeholder' => 'Choose Companies', ], 'settings' => [ 'width' => '50%', ], 'items' => $dataList, 'attribute' => 'name', ]); ?>

I want to show the selected companies of the user. I have a table user_companies having fields
id, user_id, company_id.
e.g one user has many companies association is used.

You need to set company_id attribute like an array with selected id of user's companies.
Short instruction:

• If company_id is the real user's model attribute, or it's used in another places in your code, add a new attribute for this case, for example companyArray.

// User.php (user model)
protected $_companyArray;

• Set the needed value for your companyArray attribute in the same model.

// User.php (user model)

// Setter for $_companyArray
public function setCompanyArray($value)
{
    $this->_companyArray = $value;
}

// Getter for $_companyArray
public function getCompanyArray()
{
    // Note $this->companies is the has many relation that must be specified in "User" model 
    if ($this->_companyArray === null && !empty($this->companies)) {
        $this->_companyArray = [];
        foreach ($this->companies as $company) {
            $this->_companyArray[] = $company->id;       
        }
    }
    return $this->_companyArray;
}

• Use new attribute in your _form view. ... field($model, 'companyArray') ...
• Profit!
