What is the upper limit for fixed drop list values that we create for screensets in OTM?

Summary:

Hello All,

The client requests that as many as 4000 values be added to the dropdown menu on a screenset that users will use to select and update a record.

So I wanted to know if OTM is capable of holding these many values there and if it can, will there be any problem with the performance of the screen? the new screen might be used in enhanced workbench.

There is no as such upper limit mentioned in OTM documentation.

And if everything is fine, how do we add these many values and display values efficiently while setting up the screen set?
