MasudHossain Often times a task does not have a start or end date, so we should be able to add tasks without a start or end date. And then we should be able to click on a cell for that task to add the start + end dates for it. Example of how Clickup does it: https://github.com/user-attachments/assets/fd0abc61-3591-4df4-a7de-762938a08642
tasha Hello MasudHossain, The start property is mandatory, the end and duration properies are optional but one of them must be appplied. So unfortunately there is no way to add a task without these data.
