* maxExpandFactor: Maximum suggestions box width relative to the textbox width. If set to e.g. 2, the suggestions box
* will never be grown beyond 2 times the width of the textbox.
* Type: Number, Range: 1 - infinity, Default: 3
- * positionFromLeft: Whether to position the suggestion box with the left attribute or the right
+ * expandFrom: Which direction to offset the suggestion box from.
+ * Values 'start' and 'end' translate to left and right respectively depending on the directionality
+ * of the current document, according to $( 'html' ).css( 'direction' ).
+ * Type: String, default: 'auto', options: 'left', 'right', 'start', 'end', 'auto'.
+ * positionFromLeft: Sets expandFrom=left, for backwards compatibility
* Type: Boolean, Default: true
* highlightInput: Whether to hightlight matched portions of the input or not
* Type: Boolean, Default: false
* @param value Mixed Value to set property with
