I am developing a calendar app and want to handle three tabs such as hours timing / out of office / holiday tabs in a form.
what is the efficient appraoch to group the form as there is one form and three tabs and only one button to create an event.
I am doing it in this way and initializing from in ngOnInit lifecycle hook and I have done it in this way.
this.eventForm = this.fb.group({
businessHours: this.fb.group({
title: ["Title", [Validators.required]],
datePicker: [""],
shifts: this.fb.array([]),
calendars: ["", [Validators.required]],
color: [""],
endDateCriteria: ["never"],
recurrenceCriteria: ["does not repeat"],
dateRangeStart: [""],
dateRangeEnd: [""],
recurrenceRule: [""]
}),
outOfOffice: this.fb.group({
// title: ['', Validators.required],
// Add other controls as needed
}),
holiday: this.fb.group({
// title: ['', Validators.required],
// Add other controls as needed
})
});
This is where I am grouping a form with three different tabs
and in the below snippet I have the .html file code where I want to show the formcontrol. But now the issue here is that I got the error of all the formControls that `core.js:6210 ERROR Error: Cannot find control with name: 'title'`
Similar errors related to other controls.

There are other tabs code as well I just have shortened it with respect to the single tab. I just want to know the effiecient appraoch with respect to handling the three tabs in a single form group . what that can be in angluar.
I am finding it difficult to handle three tabs in a single form as getting error related to formControls that these formcontrols are not found but i have used the same formControl and initiliazed it in ngOnInit.
How to efficiently handle the forms with multiple tabs so I can pick the values of the respective tab and process it further as I have a single submit button.
