Is it possible to have two forms with the same IDs and inputs on a website without any issues in Webflow?

In Webflow, it is not recommended to have two forms with the same IDs and inputs on a website. Having identical IDs for multiple elements goes against the HTML specification and can lead to various issues. Here's why:

  1. HTML Specification: According to the HTML specification, each element on a webpage must have a unique ID attribute within the same document. Having duplicate IDs can result in invalid HTML and may cause unexpected behavior in browsers.

  2. Form Submission: When a form is submitted, the browser uses the form's ID to determine which form data to send to the server. If you have two forms with the same ID, there will be ambiguity in determining which form data should be submitted, and the behavior can be unpredictable.

  3. JavaScript Conflicts: If you have JavaScript code that references form elements by their IDs, having duplicate IDs can cause conflicts and errors in your code. This can prevent your script from functioning properly and may lead to unexpected behavior on your website.

To avoid these issues, it is best to ensure that each form on your website has a unique ID and that input elements within each form are also unique. If you need to style multiple forms similarly, you can use classes or specific targeting CSS selectors instead.

Remember, keeping your HTML markup valid and following best practices not only helps avoid issues but also improves search engine optimization (SEO) and accessibility.
