-------------------------------------------------------------------------------------------


when modifying the timeslots and recurrence we should show two button for 
validate and cancel  ,


when we set a timeslot , and then set recurring , that same timeslot should show also in all the recurring days , 

when we click on one of those days , we should be able to edit the timeslots , : either for that particular day ,  or for all the recurred days that comes after it ,



1-set timeslots should show in all recurrent days , 




2- should be able to remove a specific timeslot , and choose either to remove it from just that day or every same  day 


3-for that I think we should do like this : when we click o nspecific day we get the usual dropdown with added list of the timeslots we have for that specific day : with its start time and end time and a remove button , or mayeb two remvoe buttons , one for just that day , and other for all days , 
I let you decide for that .

4- also I wanted to add a validate / cancel , when we add timeslots or remove ..etc  eveythign should be aplleid only when we validate 

what do you think is the first step to start with 





"Hi, I am working on a calendar functionality for managing time slots, including recurring events. Currently, I can add and view slots, but I'm having trouble with removing a single instance of a recurring time slot without affecting the entire series. I need help ensuring that removing a single instance only affects that instance and not others. The desired outcome is for users to be able to remove just one occurrence of a recurring slot or all future occurrences, depending on their choice."


when we click outside of dropdown , it should cancel the changes




when we add timeslot and do recurent ==> adds to stagedrecurrence and filter from stagedAvailabilities

if we validate  === > merge staged with all recurence 

we are mergin availabilties withr recurrence to render them 


when we click on active day , === > set staged recurrente timeslot to recurrente timeslots for that day 

if we remove a day ===>  add it to that specific timeslot  exceptioni nthe staged recurrent 

    we need to make sure to update the recurrence





    Functionalities:

    1- Detailed per time slot , adding indivudal nad multiple recurirng timeslots 

    2- removing time slots from a day or from all days 

    3- having ability to cancel or validate changes 

    4-having exceptions for individual recurring timeslots  (each slot)

    5- design a custom drop down for timeslots 
    

update recurrence rule to be more than 10 weeks
