I am new to the community and I’m not sure if I am posting this in the right place.  I am using Nintex Forms 2013 in a SharePoint 2013 environment.  I have a Nintex list form that contains a list lookup field displayed as a drop down list.  The drop down list gets its values from another list on the same site.  The reference list has only one column…the value I am wanting the user to select from.

Here’s my problem…  The list of values is rather large and I am trying to improve the user experience by giving them a fast way to get to the item(s) they want.  The current behavior of the field is that they can enter the first letter of the entry they want to choose and the cursor will jump to the first entry in the drop down list that starts with that letter.  Following that, if they enter a second letter, it simply jumps to the first enter that starts with that letter.  I would like to change the behavior or come up with an alternate solution that would allow the users to enter two or more letters and have it jump to the first entry that starts with the group of letters they enter.  Simple, short example…

The lookup list contains the following entries:

Bill

Kyle

Sarah

Stephanie

Stephen

Steve

Tom

If the user enters “S”, I would like for the cursor to jump to “Sarah”.  Then, if the user enters “t”, I would like for the cursor to jump to “Stephanie” (because of entering “St”).  Currently, when they enter “t”, it will navigate to “Tom” (because of entering “t”).

I have tried some other solutions like list filtering based on another control, but I am not sure how to get it to filter the list based on only a portion of the field value (e.g. first two letters).

Does anyone have good method for doing this, or can someone point me in the right direction?

Thanks!
