#'dragSetUI

#'With draggable elements, you may not want to create one at a time, 
#'instead creating a set with a common id prefix. This simplifies the process
#'to pass a vector of elements instead of using a loop or apply function to generate

#'@param id The div id of the draggable element set
#'@param textval The list with the name for each of the draggable elements
#'@return Returns the set of dragable div elements.
