Sections, headings and layout

Last updated Oct 21, 2026

What this is, and who it is for

How a form is laid out for the person entering data: grouping fields into sections, adding headings, descriptions, instructions and separators, and choosing how wide a field is and how its choices are arranged. A good layout keeps a long form readable and tells the person what to do; it never changes what is stored.

Where to find it

Drag Section, Heading, Description, Instruction or Separator from the toolbox. Layout settings are on the Style tab of the selected field (Field properties).

What you can do

  • Put fields inside a section by dropping them onto it (an empty section says Drop fields here), or with the section's Add field inside section button. Drag a field out to move it back to the form.
  • Collapse a section on the canvas with its chevron (Collapse section / Expand section) while you work. This is for the builder only; the person entering data sees the section open.
  • Duplicate a section (the copy carries all its fields, each with a new variable name: AGE becomes AGE_1) or delete it.
  • Show or hide a whole section with a visibility condition (Conditional logic): everything inside follows.

Every option

What each layout piece looks like to the person entering data

PieceAppears as
SectionA rule across the page, its label as a heading, its description below, then its fields
HeadingA heading line; sub-text below it in smaller type
DescriptionA paragraph of text
InstructionA blue call-out box (text, and smaller text below) for the person entering data
SeparatorA thin horizontal line

A section's variable name is the group key in exported design information; a section captures no value of its own. Headings, descriptions, instructions and separators have no variable and are never exported.

Where: Form builder > Section field > Basic tab. Role: eCRF Designer.

Style tab

SettingOffered forWhat it does at data entry
Bold, Italic, UnderlineSection and static contentA Heading honours italic and underline; a Description honours bold and italic; an Instruction and a Section heading ignore them. Settings that a piece does not honour do nothing
Field widthEvery data fieldFull width, Half (1/2), Third (1/3), Quarter (1/4) of the row, side by side on a wide screen and stacked on a narrow one. This is how to put two or three short fields on one line
Options layoutRadio and Multi-SelectVertical (one under another), Horizontal (in a row, wrapping), Grid (two columns)
Checkbox positionCheckboxThe box left or right of its label
HighlightedEvery field with the Style tabA faint tint behind the field
Columns (1 to 4)SectionStored with the design, but not used: fields in a section are laid out by their own widths. Use field widths instead
BorderedEvery field with the Style tabStored, but not used

The form also has a name, a code, a version label and a description; they are the form's details, not layout, and are edited on the Forms list (Versions, reopening and publishing).

Where: Form builder > Section field > Style tab. Role: eCRF Designer.

Numbering

Data fields are numbered 1, 2, 3 … down the form in the order they appear, hidden ones skipped; headings, descriptions, instructions and separators are not numbered.

What the system records

Layout is part of the form's design revision and its snapshot. Because layout can be changed in an amendment without touching any variable, the amendment's change summary classifies a pure layout change as Low.

What you cannot do, and why

  • Make a field span a number of columns freely. Only the four widths are offered.
  • Collapse a section for the person entering data. The form is always shown in full so nothing is overlooked.
  • Add a page break. A form is one long page; split a long form into several forms bound to the same visit instead.

Compliance Q&A

No Q&A applies: layout does not touch records, checks, signatures or access.
