Appending Dueling Selects

Have you ever had a large amount of data that the you want the user to be able to select multiple values from? Is the data too large for the user deal with all at once? Or is the data to be selected broken up into different categories? This component is an alternate version of the regular Dueling Selects component. Although it looks very similar to Dueling Selects, the behavior of the data movement is different. Rather than moving data out of one box and into the other, this component copies data into the right-hand box and removes data from it. The left-hand box can be reloaded with different sets of data without changing the contents of the right-hand box.
