Hi, So to answer your questions that were asked at first : - To sort descending an Array : - You sort it with the JS native function sort() - You use sortBy and return "-your_array.indexOf(current_element)"
- To sort alphanumeric fields : - It's already done by the sort function, but if you want to change this, add/substract max values of the field in the sortBy function to place it where you want. All of this is theorical, it heavely depends on your data et what you want to achieve with it. Maybe a practical example of what you wish to accomplish could help ;) Regards, Julien.
