How to remove a record from enum list added by the user

[long_shot]

My enumlist allows user to add values and based on that,  I update my enum list every month after checking what all list of items added in the enum list suggested values while filling a form.  My objective is to remove the list of items which are added by the user by not relevant in the enum list.

Also i have already used   - LIST("itemName1","itemName2")   as a subraction from suggested value formula and it is not working.

Where come from the update list? and why do you use enumlist type?

If you want dinamic suggestions, use text type or data type needed and in Suggested values use the filter that is relevant whith your user.

With that we come back to the first question: Where come from the update list? once identify, filter this data as you need and those values will be your dinamic suggest values.

In the configuration of the EnumList column, disable Auto-complete other values.

To add to Steve's response, here is a video that explains it as well. I was in the same boat, and found both Steve's response and this video helpful.
