I have complex symbol, which can (imaginary) exist in different states.
For example, in treeview control node can be either expanded or collapsed, which means different indication.
I want to have one symbol/prototype, but multiple instances of it in different states.
Is it possible in Illustrator?
Rephrasing the question: are all instances of the symbol obliged to be identical to it's prototype in Illustrator?
This is not true in programming: a class instance can differ from prototype by field values. For example, different instances of a vector can have different coordinates.
So, for example, can I have a symbol for tree view indicator, which can be in two states, expanded and collapsed, like here
