Configure descriptive tooltip text on column headers to provide inline guidance about what data to enter in each column, reducing the need for external documentation and training.
Add the headerTooltip property to any column definition in your risksheet.json:Step 1. Open your risksheet.json configuration file.Step 2. Add the headerTooltip property to the target column:
{ "columns": [ { "id": "sev", "header": "S", "binding": "severity", "type": "rating:severity_scale", "headerTooltip": "Severity (S): Rate the severity of the failure effect on a scale from 1 (minor discomfort) to 10 (loss of life)." } ]}
The tooltip text appears when the user hovers their cursor over the column header area.
Apply tooltips across your FMEA risk assessment columns to create a self-documenting table:
{ "columns": [ { "id": "sev", "header": "S", "binding": "severity", "type": "rating:severity_scale", "headerTooltip": "Severity: Rate the potential harm from 1 (negligible) to 10 (fatal)." }, { "id": "occ", "header": "O", "binding": "occurrence", "type": "rating:occurrence_scale", "headerTooltip": "Occurrence: Rate the likelihood of the failure cause from 1 (remote) to 10 (almost inevitable)." }, { "id": "det", "header": "D", "binding": "detection", "type": "rating:detection_scale", "headerTooltip": "Detection: Rate the ability to detect the failure before it reaches the end user from 1 (certain) to 10 (undetectable)." }, { "id": "rpn", "header": "RPN", "formula": "commonRpn", "headerTooltip": "Risk Priority Number: Calculated as S x O x D. Values above 150 require mitigation action." } ]}
Tooltips are especially valuable for columns with abbreviated headers (like “S”, “O”, “D”, “RPN”). The short header saves table width while the tooltip provides full context on hover.
Header tooltips appear on column headers only. Per-cell tooltips (showing help text when hovering over individual data cells) are not currently supported. If you need cell-level guidance, consider using conditional formatting to visually highlight cells that need attention.
In Risksheet versions before 24.3.3, header tooltips could block the sort and filter buttons on narrow columns. Workaround: widen the affected column by dragging the column border before sorting or filtering. This issue was fixed in version 24.3.3.
A full FMEA column configuration with tooltips across all risk parameters:
{ "columns": [ { "id": "failureMode", "header": "Failure Mode", "binding": "title", "headerTooltip": "Describe the way in which the system element could potentially fail to perform its intended function.", "level": 2 }, { "id": "failureEffect", "header": "Effect", "binding": "description", "headerTooltip": "Describe the consequence of the failure mode on the system, subsystem, or end user.", "level": 2 }, { "id": "sev", "header": "S", "binding": "severity", "type": "rating:severity_scale", "headerTooltip": "Severity: Rate potential harm from 1 (negligible) to 10 (loss of life). Per ISO 26262.", "level": 2 }, { "id": "cause", "header": "Cause", "binding": "title", "headerTooltip": "Identify the root cause or mechanism that leads to the failure mode.", "level": 3 }, { "id": "occ", "header": "O", "binding": "occurrence", "type": "rating:occurrence_scale", "headerTooltip": "Occurrence: Rate failure likelihood from 1 (remote) to 10 (almost certain).", "level": 3 }, { "id": "det", "header": "D", "binding": "detection", "type": "rating:detection_scale", "headerTooltip": "Detection: Rate ability to detect before delivery from 1 (certain detection) to 10 (undetectable).", "level": 3 }, { "id": "rpn", "header": "RPN", "formula": "commonRpn", "headerTooltip": "Risk Priority Number = S x O x D. Threshold: >150 = Medium, >350 = High priority.", "level": 3 } ]}
