create/delete a gruop of component by using button

forgive me if im too greedy to ask so many things in one post

I have searched for this issue but still can't find similar cases

my question is as title ,

is it possible to tell the app to create or delete a group of component which has already 

been set on the screen

I uploaded a picture to explain my question

for instance 

I want to make a little "meal ordering app" as shown in the pic

there are groups of components consist of 

1.a label showing the sequence 

2.a label displaying ordered meal 

3.a label showing price

 for each line on the list

and when user presses the "add" button

the app will add a new line just as the above one ( I marked it with red pen , which I mentioned as

"the component that is already been set")

and the component beneath will automatically move lower to make space for the new added line

in addition

if the user press the blue button 

the order will be remove from the list (i think it will be just the same as creating)

im not really making this app ,

but I do need similar technique ,

please help me if you have time

thank you guys masters !!

best wishes to you! 

btw, if you are willing take my questions privately

please let me know

thank you so much :))))

you can't create components during runtime, but you can prepare them and set them to visible = false, then if you need one of them, set its visibility to true

Use a ListView and a list.
