Hi everyone,

I have a dropdown with a selection of dates in it like below (from a lookup list) 

14/08/2020 - 10/09/2020

21/08/2020 - 17/09/2020

28/08/2020 - 28/09/2020

On my form I want to remove or hide one or more of the dates above if they are in the list the form is attached to. So for instance if a person has already selected 14/08//2020 - 10/09/2020 then this would not appear in the dropdown the user would just see the below

21/08/2020 - 17/09/2020

28/08/2020 - 28/09/2020

I've been trying to do this through various ways unsuccessfully so wondered if anyone had done something similar and could point me in the right direction.

Thanks 🙂

Hey Supersal,

 

I had to do something similar a couple of years ago. I used a 2 step-approach using a source list and a user list;

- in the real source list you can add all the values required

- a workflow then copies these values as they are added in the user list which will be used as lookup

- if a user has selected an item, a second workflow (or part of the current process) removes the selected value from the user list.

 

Maybe there are better ways, but this was easy to implement and manage for my case.
