# Merge

![Symbol](../../../img/gridconfig/operator_merge_symbol.png)

Merges all child elements to one result array.

Configuration Settings: 
 - Label: Label of column.
 - Flatten: If a child value is an array itself, its items will be flattened and added as separate 
   items to the resulting array.  
 - Unique: Return only unique array values (calls `array_unique()`).
