Custom fields

Where custom fields are defined. What they are for, and how they differ from tags, is in Custom fields.

Defining a field

Each row is one field:

Column	What it does
Label	What appears on the record.
Key	The stored identifier. Kancil suggests one from the label.
Kind	Decides the input control.
Options	For choice kinds — entered comma-separated.
Required	Makes the field mandatory.
Pos.	Order the fields appear in.

The key

The key is the one to get right first time. It is what the value is stored under, so changing it later leaves existing values filed under the old key, where nothing will look for them.

Take the suggestion unless you have a reason not to. Changing a label later is free.

Required fields

Marking a field required affects records you create from then on. It does not retroactively invalidate records that predate it — but it does mean editing an old record may now ask you to fill in something you never had a value for.

Use it for the fields that are genuinely mandatory, and let the rest be optional.

Order

Position controls the order on the record. Put the field you fill in every time at the top; a form ordered by how it was built rather than how it is used costs a moment on every record forever.
