Customizing PlanningCalendar: Adding Headers & Expandable Rows

[SrikanthVudharapu]

Hello,

I’m working with UI5 Tooling and need to customize the PlanningCalendar control to use within an Angular application. Specifically, I want to:

1. Add extra headers/columns to the table.
2. Implement expandable rows within the table.

Is it possible to make these customizations using UI5 Tooling, or is it limited to modifying basic UI elements such as buttons? I have reviewed the API reference but have not found a clear approach to achieve these changes.

If these customizations are feasible:

• Can they be implemented using UI5 Tooling, or would another approach (such as the UI5 SDK) be more appropriate?
• Should I extend the control or create a custom one for this functionality?
• Are there any relevant examples or documentation available?

If these options are not suitable, I’d appreciate suggestions on other methods to achieve this.

Thank you for your help!
