limitation of option

[Admin]

We cant add more than 55 option in the Description fields ?

Is there are a limit  number for subtask , Since we add subtask but its now  not appear in the list  ?

Is their a limit for number of subtasks  once we Applied filter?

 Regarding the board, not all subtasks appear?

Hi @Rula Nayef and welcome to the community!

Am I correct in my understanding that you're trying to add more than 55 sub-tasks to a single issue?  

I would have to ask why.  From a usability standpoint, even if Jira were to support that many, it would seem like an undesirable experience for those needing to view and manage all of the work.  Can the parent issue be chunked into a smaller effort so that each parent issue has a more manageable number of sub-tasks?
