Custom fields

Every team tracks something extra: the firmware flashed on each board, which test rig it’s on, when it was last calibrated. Custom fields add those to every prototype. They’re part of the Business plan.

Adding a field

Admins and owners go to Organisation settings → Custom fields, then give the field a name and a type:

Type	Good for
Text	Firmware version, fixture ID, PO number
Number	Idle current, cycle count, hours on test
Date	Calibrated on, shipped on
Choice	Test rig, build house, enclosure colour
Yes / no	Burn-in done, conformal coated

Choice fields need a list of options. You can add help text, which is shown as a hint when someone fills the field in.

You can rename a field and change its choices later. A field’s type can’t be changed once it’s created; add a new field instead. Removing a choice doesn’t change prototypes that already have it.

Filling them in

Custom fields appear on every prototype page under Custom fields. Type a value and press Enter (or click away) to save; choices and yes/no save straight away. Clear a value to remove it. Every change is recorded in the prototype’s history with the field’s name, the old value and the new one.

You can also fill them in when importing a spreadsheet.

Seeing and filtering them

• On the Prototypes list, custom fields appear as extra columns. Use Columns (in the filter panel) to choose which ones. The choice is remembered in your browser.
• Choice and yes/no fields get their own filters.
• Search also matches custom field values.
• The JSON export includes field definitions and values.

Deleting a field

Deleting a field removes it from every prototype. The values it had stay in each prototype’s change history.

If you move to the free plan

Nothing is deleted. Existing fields and values are still shown and exported, but can’t be changed or added to until you subscribe again.
