Whether to draw a "placeholder" event while the user is dragging.

<div class='spec' markdown='1'> Boolean/Function, *default*: `false` </div>

This option only applies to the agenda views.

A value of true will draw a "placeholder" event while the user is dragging (similar to what Google Calendar does for its week and day views). A value of false (the default) will draw the standard highlighting over each cell.

A function can also be specified for drawing custom elements. It will be given 2 arguments: the selection's start date and end date (Date objects). It must return a DOM element that will be used.
