Dropdown list - Unique Items

Jump to solution

I am not finding a recent answer to this question.   The only answer is 4 years old.   

 

I have a list that I need to use as a dropdown in a Nintex form.    It does contain duplicates and I want to only display unique items.   In InfoPath this was the 'Show only entries with unique names' option.

 

This apparently wasn't possible in 2015, has it been updated to have this capability now?

Hi,
At present this is still not possible to do with the Nintex Lookup control.
The reason for this is because we may see duplicates but what the control sees is unique item ID's so it can determine which selection has been selected even though the name is the same.
How would the control know which ID to filter out?
I think the best approach here would be to rethink the solution and eliminate duplicates in your lookup.

In other programs such as InfoPath it's an option that you can choose.   You would choose it if you were using the value to filter another list.  In that instance you would only need the value and not the id so it wouldn't matter.  As a matter of fact in a dropdown it would actually be pointless to see duplicate items unless there was some other piece of information attached that allowed you to select the correct one.  Otherwise how would you know which one to pick?

 

Just as an example.   If the first option in a cascading dropdown scenario has duplicates you can set it to only show unique names.  Then you can use that to filter what is shown in the next dropdown.

 

So if a value in my first dropdown is 'All', I only need to see and select one to filter the next dropdown to show all items where a secondary column value is 'All'.

 

It's very common and works well.   I used it for years in InfoPath.

 

Eliminating duplicates is a lot of extra work and significantly increases the size of the lists involved.

I totally agree with what you are saying but the SharePoint way of doing this is to make sure the lists are setup efficiently to avoid duplicates.
