How to add Petition Form to a Webflow website

Embed Petition Form on Webflow

01

Create a Petition Form plugin for Webflow on Common Ninja

First, create a Webflow Petition Form plugin on Common Ninja. On the plugins catalog, find the Petition Form and enter the Editor.

02

Save the Petition Form plugin

When you're done creating the Petition Form plugin, click on the Save Changes button at the right top corner of the editor. If you don't have an account on Common Ninja, you'll have to register first.

03

Copy the Petition Form Embed Code

When you're ready to add the Petition Form plugin to your Webflow website, click the Add To Website button at the top bar of the Editor. On the window that opens, click the Copy Icon to copy the plugin embed code. In the next steps, you will paste this code into your Webflow website.

04

Paste the code to your Webflow website’s HTML field.

Next, go to your Webflow website editor and find the HTML field. It is most likely in the form of an HTML/Code widget or module which you can find on the Webflow’s editor. Add it to your page, and paste the Petition Form Embed Code you’ve copied before to the HTML field. Save and update, and that’s it, you should have Common Ninja’s Petition Form plugin on your Webflow website.

05

Alternative Method 1: Through the HTML option in the text’s editing area.

If you can't find the HTML/Code widget or module, there's another way to put Common Ninja’s Petition Form plugin on your Webflow plugin. You can just add the code to a special HTML section in the text editor.

06

Alternative Method 2: Add it directly to your Webflow website’s HTML code.

If you're having trouble finding a widget or a special part in your text editor where you can add the Embed Code, you can try a different way to add the Petition Form plugin to your Webflow website. You can do this by putting it straight into your Webflow website's HTML code.

Why Use This Widget

Use the Petition Form widget when your goal is to gather visible support around a cause, policy, or initiative. It lets visitors sign with their details in a structured way that can be stored, exported, and used in campaigns or official submissions. You can describe the issue clearly, show how many people have already signed, and keep participants informed through notifications. This tool is valuable for nonprofits, advocacy groups, community organizers, and internal company initiatives that depend on collective backing. By hosting the petition on your own site, you control the experience, keep visitors connected to further information, and build a base of supporters who feel involved and heard.
