This checklist enables a quick review of form layouts and helps enforce consistent standards across projects.

Example layout of an order form

Main layout

Design compactly; avoid oversized fields and large label-field gaps (use field widths that fit the content).
Avoid placing several fields side by side – except tightly related fields (zip + city, date + time, actual + target).
A TabbedPane (if present) should use the full available height and width.
From 3–4 fields onward, use layout panels for sensible grouping.
Title of the first layout panel (top left) = the BO name.
Each layout panel needs at least one column with „use remaining width“ (possibly the label column).

Always hide the default border.
Instead add left/right columns and top/bottom rows of 5 pixels (default border).
The default spacing between two objects and between two rows is 5 pixels.
Above a TabbedPane always add a standard row of 22 pixels height.
Spacing between adjacent subforms: 20 pixels.

Subform components always belong in a TabbedPane (even for a single subform).
If a tab contains only one subform or a text area, it should fill the tab without borders.
Multiple subforms in one tab get explanatory headings.
Fields with file attachments need a border (e.g. engraved, lowered).
Prefer placing text areas in their own layout panel (with border) or their own tab (no border).

Choose „do not clone“ and „active“ deliberately per component.
Set non-writable fields (calculated / rule-driven) to inactive.
Reference fields with few entries (≤ 10, e.g. salutation, priority) as combo boxes, otherwise as selection fields.
Constrain the selection sensibly via a value list provider (e.g. only active addresses matching the customer).
Set the initial focus to the first active input field at the top left.

Active: „hide name“ and „adopt last window settings“.
Use the „screen“ icon.
Assign the „general“ work environment to all user groups.
Configure the result list via sort order/column settings.
Publish these settings to the workspace so all users can use them as a template.

Maintenance.
