How can I create a drop-down filter for my Webflow collection list that regenerates the results based on the selected category, without navigating to a new page?

To create a drop-down filter for your Webflow collection list that regenerates the results based on the selected category without navigating to a new page, you can follow these steps:

Step 1: Set up your Collection List
Make sure you have set up your Collection List correctly, including the dynamic binding of your collection items.

Step 2: Add a Dropdown Element
Drag and drop a Dropdown element onto your page where you want your filter to be. You can customize the design of the Dropdown element to match your website's style.

Step 3: Add Categories to the Dropdown
Open the settings for the Dropdown element and go to the Options section. Here, you can add each category you want to filter by as an option in the dropdown menu. The Option Text will be the display name, and the Option Value will be the filter value that matches the category in your Collection List.

Step 4: Add Custom Code
In order to implement the filtering functionality, you will need to add some custom code to your project. Here is an example of the code you can add:

```javascript

```

Make sure to replace `'your-dropdown-id'` with the actual ID of your Dropdown element. Additionally, make sure your collection items have a `data-category` attribute that matches the filter values set in the dropdown options.

Step 5: Apply Filtering to Collection Items
Add the class name `'collection-item'` to each Collection Item element that you want to be filterable. This class name is used in the custom code to loop through and filter the items.

That's it! Now, when a user selects a category from the dropdown, the collection list will be regenerated based on the selected category without navigating to a new page. The code listens for the change event on the dropdown and filters the collection items based on their data-category attribute.
