You have three options: 
1. With Emoji Flags
2. Without Emoji Flags
3. Without the Nice Select

DISCLAIMER: the countries are loaded in with JS - so you wouldn't be able to see them on Webflow however when you publish - Voilà!

Tiny House Configurator

Duncan Hamra

Happy Wednesday! I noticed people were looking for an easy way to confirm password fields in Webflow, so I decided to create this!

There are a few solutions available today, but they don't give much (or any) style control or user feedback while the user is typing. This project does both!

It uses some custom code from Stack Overflow + some custom CSS to style neighboring elements. Tutorial video in the project.

Works with Memberstack, but you're welcome to adapt to any project! I hope it serves you well 😁

Confirm Password

Memberstack

Had some fun rebuilding Webflow's signup, login, and forgot password UI inside Webflow. Social login and account creation are powered by Memberstack. 

The form validation and the show/hide password are powered by some custom code. 

The video tutorial on the homepage explains how it all works.
