Behaviour change on clicking on a calendar (design)

[Aveyron-RetD]

Is your feature request related to a problem? Please describe.

When selecting on a calendar, the calendar automatically hides away and goes on the hidden calendar section

I believe this behaviour should be changed

Describe the solution you'd like

On selecting the calendar => all the other calendar hides away and i am left with a simpler view.
The event creation are now automatically set on this calendar.
On re-selecting the calendar all the calendar that were "hidden and selected" are shown again.

Describe alternatives you've considered

No response

Additional context

Only the tick removal should hide away for good the calendar
