Custom fields in Instagantt give you the power to customize your projects, add additional task data, and build workflows that fit your team's needs. They help you track project-specific details, categorize work, and structure information in ways that default task fields can’t. Understanding how custom fields, visibility, and activation work ensures you can build more accurate reports and a more flexible workflow.
Custom fields allow you to add personalized metadata to your tasks, making your workflow more flexible and better aligned with the unique needs of your projects. They help you capture information that isn't included in the default task fields and give you more control over how work is organized and analyzed. Custom fields are created at the workbook level, and each project can decide whether to activate or hide them based on relevance.
Below are the types of custom fields you can create, along with typical uses and examples to help you choose the right option:
📝 Text
Great for open-ended information that doesn’t fit predefined categories, such as a client name, an external ID, a vendor or a location.
🗂️ Dropdown list
Ideal for structured categorizations and consistent labeling, for example task type (Feature/Bug/Research), department, workflow stage or effort level.
🔢 Decimal number
Useful for precise values requiring decimals, such as cost per unit or material measurements.
💰 Currency
Designed for financial tracking such as budget allocation, contractor rates or monetary estimates.
🔟 Integer number
Best for whole-number values like story points, revision count or number of assets.
✅ Checkbox
Perfect for simple yes/no or true/false indicators, some examples include if an approval is required, if there's a required review or a blocked status.
📊 Percentage
Helpful for percentage-based metrics, for example confidence level, ROI expectation or supplemental progress measures.
Adding the right mix of custom fields allows you to transform any project into a structured, searchable, and highly contextual workspace. Whether you're tracking financial inputs, categorizing task types, monitoring review cycles, or recording client details, custom fields give you the flexibility to build a workflow that reflects how your team actually works—without compromising clarity or control.

Creating the right fields allows teams to track everything from approvals, budget details, quantities, or any specialized information tied to your gantt chart planning.

The Manage Custom Fields window includes two toggles:

Even if a field is not visible on the task list, it will still appear inside the task details panel, as long as it is active. Even though custom fields are created at the workbook level, each project can choose whether to activate or deactivate them.
This allows different projects within the same workbook to use only the fields that matter to them.
💡 Important notes:

Custom fields can be used as filters, helping you sort, group, and narrow down tasks more effectively:
Using custom fields for filtering transforms your task list into a personal tracking dashboard tailored to your workflow
