How can I create a range slider add to cart feature in Webflow where users can select a quantity range and add it to their cart?

To create a range slider "Add to Cart" feature in Webflow, you'll need to combine Webflow's native eCommerce components with custom JavaScript to sync the slider’s value with the product quantity.

1. Add Webflow Product and Quantity Elements

• Add a Product Element to your page using the Webflow eCommerce components.
• Within the product block, add a "Quantity" input field (this is required for cart functionality).
• Give the quantity input a unique custom ID (e.g., quantity-input).

2. Add a Range Slider

• Drag in an HTML Embed or native Form > Range input component.
• Set desired min, max, and step values (e.g., min="1", max="10", step="1").
• Give this input a custom ID, like range-slider.
• Optionally, place a Text Span or Div nearby to show the selected number, give it an ID like range-output.

3. Sync Slider with Quantity Input Using Custom Code

• Add the following custom code inside an Embed component or in Page Settings > Before tag:

<script>  document.addEventListener("DOMContentLoaded", function() {    const slider = document.getElementById("range-slider");    const quantity = document.getElementById("quantity-input");    const output = document.getElementById("range-output");    function updateQuantity(val) {      quantity.value = val;      if(output) output.innerText = val;    }    if(slider && quantity) {      // Initialize quantity      updateQuantity(slider.value);      // Update quantity when slider changes      slider.addEventListener("input", function() {        updateQuantity(this.value);      });    }  });</script>

• This code automatically syncs the slider value to the native ecommerce quantity field, so when a user submits the Add to Cart form, it uses the selected range value.

4. Publish and Test

• Publish your site to check this functionality in the live environment.
• Interact with the slider, add product to cart, and verify correct quantity is added.

Summary

You can implement a range slider "Add to Cart" feature in Webflow by syncing a custom range input to the native eCommerce quantity field using JavaScript. The slider updates the quantity dynamically, allowing users to easily select and purchase multiple product units.
