To hide the section just define a flag variable which can hold true or false. In the button layout's button saveInto toggle the flag to true. Now, if you are on new versions in the sectionLayout showWhen parameter provide the value as flag. 
 If you are on earlier versions just use an if(flag,a!sectionLayout(),{}). Hope this helps.

Hi Srinivas, I recommend that you populate the showWhen field of a!sectionLayout with the logic that determines when you want the section to display. Hope this helps!

Hi @srinivas you cannot compare a Normal section behaviour with an editable grid. 
 I mean to say, when you click on delete icon within an editable grid, 1 row gets deleted from your DB, and because this row do not exist hence one row will be disappeared from your grid. 
 But when we talk about section, you can hide this section conditionally, let's say, you want to delete a row from db which is currently being display in this section, in such case you can have a delete button which invoke delete from data store entity smart service function to delete this row based on given identifier, and you can make the use of showWhen property of section layout where if the data do not exist, do not show this section. 
 But still we can't call this as deletion/removal of section layout, instead we can call it as display section layout conditionally or hiding the section layout based on some certain condition. 
 Hope this will help you.
