Unscheduled task show 1 day duration

[nikunjpatel99]

1. if i mark any task as unscheduled than it take 1 day as duration if the task is not unscheduled that way should show duration ?

2. if i have only start date in that case lib take 1 day as duration and caculat enddate of that in that what if only want so the startdate.

so basically it is possible to show only start date of task ?

i have dhtmlx-gantt : "^8.0.10" inside my project

@nikunjpatel99,
Gantt expects that every task will have the date parameters (start_date, end_date, and duration).
When you load tasks without enough date parameters Gantt assigns them from their children or from other tasks. But in that case, you won't be able to drag or resize these tasks.
You can check how it works in the following sample:

If a task is unscheduled, Gantt still adds the dates to the task object.
By default, the dates for these tasks are not displayed, but Gantt doesn't change that for the duration column:

If you don't want to show the duration for unscheduled tasks, you can use the template function in the column configuration and return an empty string:

Here is an example:

And you can use the same approach, if you want to show the start date for unscheduled tasks:
