Doesn't work with flexibox? Or table?

[posel]

Describe the bug

The calendar is open always on the left side of page:

Picker is opened from the field in the middle of the screen (Planned from or to).
When flexibox reposition items, everything remain ... wrong. Here is small width for mobile screens:

Page has structure
flexibox > div > table > row > cell > div with div for picker, input items, button

Whataver I do date picker opens always on the left side of the screen

Is there a way how to persuade him to stay upon the the box?
Herer are both opens

To Reproduce

I believe that the same structure would make always the same problem:

const elP: DTPickers = { attrtype: attrType }
const divCont: HTMLDivElement = this.fhtml.createHTMLel('div', undefined, 'linkFieldDiv') as HTMLDivElement
const PickerCont: HTMLDivElement = this.fhtml.createHTMLel('div', undefined, 'linkFieldDiv') as HTMLDivElement
const inEl: HTMLInputElement = this.fhtml.createHTMLel('input', Date_${attr.name}, 'linkFieldDiv') as HTMLInputElement
const bSelect: HTMLDivElement = this.fhtml.createHTMLel('div', undefined, fieldButton, divCont) as HTMLDivElement
bSelect.innerHTML = iconProvider.get('calendarSVG')
divCont.appendChild(PickerCont)
divCont.appendChild(inEl)
divCont.appendChild(bSelect)
attr.UIdataElType = 'datetime'
attr.UIdataEl = elP
lBox.buildEl.lastItem = undefined
lBox.buildEl.colItem.appendChild(divCont)
// set picket
const dtFormat: string = attrType === 'datetime' ? 'dd. MM. yyyy hh:mm' : 'dd. MM. yyyy'
if (attrType === 'date' || attrType === 'datetime') {
elP.dateP = new DatePicker(PickerCont, {
date: new Date(attr.oldValue)
input: { format: dtFormat, element: inEl },
showAlways: false,
timePicker: attrType === 'datetime',
usageStatistics: false,
autoClose: true,
openers: [bSelect]
})

Steps to reproduce the behavior:

Expected behavior

Open under or over the field with the date, not out side

Additional context

[posel]

I have found that if I use a style for wrapper a style tui-datepicker-input tui-datetime-input tui-has-focus (btw I didn't find anywhere that it is necessary) it keep calednar close (over) the date element:

Nevertheless it is even less usable because it does not enlarge the eleement in which the item is. BTW in style there is no any limit for size, but the picker does not adept the box size. It is visible here - both width and height has size open:

Regret to say, but I return back to the standard browser input element.
