How to click each and every value from dropdown box in Angular project

I am working in anjular project and i facing some issue during automation, My question is : I have container box which is not stable value ( Ex: when i create new item that will be added in that container box). How to click on each and every link from that box.

Note :

  1. That box value not stable( some time 4 value is there and when i create new one then the box value will be 5, 6 .7…upto “n” value).

  2. when i click One value from that container box then, after click on that value will be hide from table and when i click on same value again that value will be unhide from the table.


Kindly advice how to do that.
