Hi Thiago,
Thank you for contacting Syncfusion Support.
We have analyzed your query and would like to make a few points known.
- Currently, we do not have support for three tiers in the Gantt timeline. However, you can use the month-week or year-week combinations in the timeline settings to view the weeks in your timeline.
- We also have another option: To make use of the toptier.count and bottomtier.count properties. By using these properties, we can combine the cells in the bottom tier to represent weeks. We have prepared a Sample demonstrating this.
We hope this is would be enough to meet your requirements. If not, please provide us with further details on what you want to achieve.
Please contact us if you require any further assistance.
Regards,
Monisha.
