This sample demonstrates the Gantt header template feature. In this sample, custom icons have been shown in the column headers.
The Gantt provides a way to define a custom element in header element. The columns -> headerTemplate property accepts the template for the header cell.
In this demo, we have rendered the customized template for all column headers.
Gantt component features are segregated into individual feature-wise modules. To use selection feature, we need to inject the Selection into the Inject Services section.
More information on the Essential® React Gantt Chart can be found in this documentation section.
