$filter public property
The HTML code representing a filter input (e.g. a text field, a dropdown list) that is used for this data column. This property is effective only when yii\grid\GridView::$filterModel is set.
- If this property is not set, a text field will be generated as the filter input;
- If this property is an array, a dropdown list will be generated that uses this property value as the list options.
- If you don't want a filter for this data column, set this value to be false.
