Retool is highly hackable, so you’re never limited by what's available out of the box. If you can write it with JavaScript and an API, you can build it in Retool.
You can write JavaScript almost anywhere inside of Retool. Just wrap an expression with double brackets like {{ Math.max(select1.value, 10) }} and it’ll execute as sandboxed JS. Using Transformers, you can write larger, reusable blocks of code for manipulating data. There’s also a native API for directly interacting with components and queries via JS.
