How can I enforce numeric input in form input fields in Webflow?

To enforce numeric input in form input fields in Webflow, you would need to utilize custom code or third-party libraries since Webflow does not offer a built-in feature for input validation.

Here's a step-by-step guide on how you can achieve this using custom code:

1. Add an HTML embed element to your Webflow project where you want the numeric input field to be located.
2. Open the HTML embed element and paste the following code inside the `` tag:

```html

```

3. In the same HTML embed element, create the input field and add the `restrictInput(event)` function to the `onkeydown` attribute of the input element. This function will validate and restrict the input to numeric characters only.

For example, if your input field has the class name "numeric-input", the code would look like this:

```html
<input
class="numeric-input"
type="text"
onkeydown="restrictInput(event)"
/>
```

4. Customize the input field styling and other properties using Webflow's Designer.

5. Publish your Webflow site to make the changes live.

Now, whenever a user tries to input non-numeric characters into the designated input field, the code will prevent it from appearing. This ensures that only numeric values can be entered.
