Add Header Tooltips

Add the headerTooltip property to any column definition in your sheet configuration: Step 1. Open your sheet configuration sheet configuration. Step 2. Add the headerTooltip property to the target column:

{
  "columns": [
    {
      "id": "sev",
      "header": "S",
      "bindings": "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.

Add Tooltips to Multiple Columns

Apply tooltips across your FMEA risk assessment columns to create a self-documenting table:

{
  "columns": [
    {
      "id": "sev",
      "header": "S",
      "bindings": "severity",
      "type": "rating:severity_scale",
      "headerTooltip": "Severity: Rate the potential harm from 1 (negligible) to 10 (fatal)."
    },
    {
      "id": "occ",
      "header": "O",
      "bindings": "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",
      "bindings": "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.

Write effective tooltip text by following these guidelines:

Guideline	Example
Start with the full column name	”Severity (S): …”
Explain the expected value range	”Scale from 1 to 10”
Describe the business meaning	”Rate the potential harm to the end user”
Keep text concise (1-2 sentences)	Avoid multi-paragraph explanations
Include threshold guidance where applicable	”Values above 150 require mitigation”

Current Limitations

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 Nextedy 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.

{
  "columns": [
    {
      "id": "failureMode",
      "header": "Failure Mode",
      "bindings": "title",
      "headerTooltip": "Describe the way in which the system element could potentially fail to perform its intended function.",
      "level": 2
    },
    {
      "id": "failureEffect",
      "header": "Effect",
      "bindings": "description",

      "header": "S",
      "bindings": "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",
      "bindings": "title",
      "headerTooltip": "Identify the root cause or mechanism that leads to the failure mode.",
      "level": 3
    },
    {
      "id": "occ",
      "header": "O",
      "bindings": "occurrence",
      "type": "rating:occurrence_scale",
      "headerTooltip": "Occurrence: Rate failure likelihood from 1 (remote) to 10 (almost certain).",
      "level": 3
    },
    {
      "id": "det",
      "header": "D",
      "bindings": "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, >250 = High priority.",
      "level": 3
    }
  ]
}

Verification

After saving your configuration changes and reloading the Risksheet page, you should now see:

A tooltip popup appearing when you hover over any column header that has headerTooltip configured
The tooltip text matching exactly what you entered in the configuration
Sort and filter buttons remaining accessible (on version 24.3.3 or later)
