How to add new buttons (matrix) from code

I want to add new textboxs every time i click a button.
Is it possible to add new objects from code ("Blocks")?
or the ones I add at "Designer" are the only ones I will be able to use...

you can't create components dynamically

you can prepare components as much as you think you might need an hide them

then if you need one of them, set its visibility to true
