Masked Input 
Easily add inputs to your web app that need to match a specific pattern—like phone numbers!

Configuring the Masked Input 
The Masked Input is just like the regular input in WeWeb, but with a twist—you get to add a pattern mask! Here's a quick guide on how to set up your pattern:
A pattern mask is simply a string like this: '{#}000[aaa]/NIC-``*[**]'
Here's what each part means:
- 0: any digit
- a: any letter
- *: any character
- []: makes the input optional
- {}: includes a fixed part in the unmasked value
Check out these examples, each demonstrating how to use pattern masks for different types of inputs:
