Create a Signup Form in Webflow

Article author

Memberstack works with signup, login, and profile forms that you create in Webflow. Here’s how to integrate your custom Webflow login form with Memberstack.

A. Copy & Paste

This method is the fastest and most highly recommended. We have hundreds of customizable components you can use to get started. 

1. Pick from over 200+ free components or start with an unstyled signup form

2. Copy the form element and paste it into your project.

All of the attributes and custom code you need have already been set up for you.

What's next?

Next up, let's add a custom field to collect additional information from members. Custom Fields & Inputs. This article is part of the official Getting Started Checklist



Every Memberstack project comes with a set of default modals which can be launched with a link. 


Step 1 → Create a signup link or button on your site.


Step 2 → Add the following attribute to your link. The attribute name is data-ms-modal and the value is signup.signup_attribute.jpg

That’s it! → The signup modal will display when the button is clicked, and the button will disappear once I member is logged in. 


C. Start from Scratch

Step 1 → Build a form in Webflow

  1. Add a form block.
  2. Add the required input fields (email and password) and any additional fields you want to collect data for. These can be checkboxes, radio buttons, select fields, or test areas.

Step 2 → Add the Memberstack data attributes

  1. Add data-ms-form="signup" to the <form> element.
  2. Add the data attributedata-ms-member="email" to your email input.
  3. Add data-ms-member="password" to your password input.

Optional Step 3 → Add custom fields

  1. If you have custom fields, you’ll need to add them to your database in Memberstack. Create Custom Fields
  2. Memberstack will generate a field ID for each, which you will need to add to Webflow. The attribute will look like data-ms-member="custom_field_id", data-ms-member="name", data-ms-member="phone", etc.
  3. Your form is ready to start adding members to your memberstack application!


Can I have multiple signup pages. 

Yes! You can have as many different signup pages as you like.

Can I have more than 1 signup form per page?

Yes! With Memberstack 2.0 you can now have more than 1 signup form on the page. Please remember to not assign all the forms the same id though.

    On B, step 2, it wasn't clear to me as a newbie that I wasn't supposed to just paste in the highlighted code, but instead split it up as pictured. Might want to clarify in case other users are as dense as I am. :)

    Why aren't there boxes to collect payment information?

    Can you have them set their password after sign up?

    Payment information is collected by and stored in Stripe. The data entered into the sign up form is collected by and stored by Memberstack. If a member clicks on a data-ms-price:update attribute before signing up they will be prompted to checkout right after signing up.

    Hey Duncan Hamra,

    Is there a video of this functioning?

    The concern is that it's too many clicks and you are losing conversion. 

    Sign up is supposed to be name, email, and payment info. Then one click to purchase. Simple and straightforward.
