# Using Building Blocks

## 1. Dynamic Inputs

All building block input fields support:

* References to variables and tables — "Hello {id: 123, name: "Profile name"}
* Code in inputs — "This is my secret password stored only locally: ${await zw\.deviceStorage.get("password")}"
* Spintax to randomize input — "{ Hi | Hey | Howdy }! How { are you | are things going }?"
