Harness the power of Symbols, by nesting them.
To create a nested Symbol, just drag an existing instance into another Symbol’s master. It’s that simple! Any updates you make to the Symbol’s master will see the changes propagate throughout your design no matter if they’re inside another Symbol or not. As well as dragging an existing instance into a master, and inserting via the toolbar item, you can also select multiple instances of different Symbols and press Create Symbol in the toolbar.
There’s no limit to how deep you can nest Symbols, but please note a Symbol cannot contain an instance of itself.
As mentioned in the Editing Symbols chapter, nested Symbols can also be overridden, along with images and text in a Symbol’s instance.
Overriding a nested Symbol will allow you to swap out any Symbols contained in an instance – with any other Symbol that is the same size. Say you had a Symbol of a toolbar that contains a Symbol of an icon. With the overrides, you could swap out the icon Symbol, with a Symbol of another icon – or nothing at all. These nested overrides mean that you can have fewer Symbols that are similar, and have more power and control over individual instances.
