Boolean Field

Tips & examples

A read-only checkbox representing the output evaluation of a boolean expression.

When to use

Presenting simple binary flags or states (true/false) to users.
Evaluating conditional dynamic expressions that resolve to a boolean or null value.

Examples

Displaying a read-only checkbox representing an active/inactive record state.
Evaluating checkmark UI indicators using conditional true/false/null backend logic.

Avoid

Using for interactive form inputs where users need to check or uncheck a box to submit data, use boolean_input instead.
Allocating large layout grid dimensions (e.g., spanning multiple rows or wide column blocks), keep this compact display element restricted to 1 row height and 1 to 2 grid columns.
Writing complex string or object expressions in the booleanExpression textbox instead of resolving directly to boolean values (true, false) or null.

Properties

Editor properties

Configure these in the Application Designer property panel. Group headings mirror the editor where possible. Data Source is where the element gets its rows or field binding (a view/query, a connector operation, or a parent form field). References appear only for view-backed sources and map foreign-key ID columns to readable labels from another view.

Setup

ValuerequiredCustom expression: An expression textbox resolving to true, false, or null (defaults to ’true’). Used to compute the checkbox checked state dynamically.
Example true
Default: buildCustomExpressionValue(true)

Sizing

No size of its own: dropped at the platform default of 1 × 1 grid cells and resized on the page.

Accessibility

Renders as a native disabled checkbox component. It is used as an output display only.
