How to Limit Which Users Appear in a Field

To limit which users appear in a field, you select the specific people relevant to that process instead of listing everyone. On an account with hundreds of users, this is the difference between a usable field and an unusable one.

Why showing everyone breaks the field

The default of listing every user works at ten people and fails at two hundred.

Scrolling through the whole company to find one colleague
Wrong assignments caused by similar names
Processes exposing the full employee list unnecessarily
Slow selection on a field used dozens of times a day

Two settings worth knowing

Setting	Effect
All users	The default — everyone in the account appears
Selected users	Only the people you choose are listed
Single user only	Forces one owner; selecting another replaces the first

How to configure it in Jestor

Open the multiple-users field settings in Jestor.
Note that all users is enabled by default.
Turn it off to choose which specific people should appear.
Select the relevant people — the sales team on a CRM, for example.
Enable the single-user option where a record should have exactly one owner.

Why choose Jestor for field-level control?

Switching a field to single-user in Jestor changes selection behaviour rather than just validating it: choosing a second person replaces the first, instead of allowing two and rejecting the save.

That also matters for boards, since a Kanban driven by a user field requires a single user — a card can only sit in one column.

Frequently Asked Questions

Are all users shown by default?

Yes, so you need to turn that off to restrict the list. See jestor.com.

What happens if I switch to single user?

Selecting someone new replaces the previous selection.

Why does this matter for boards?

A Kanban by user needs a single-user field.
