How can I filter the list of projects on my Webflow page by category using the top buttons?

To filter the list of projects on your Webflow page by category using top buttons, you can follow these steps:

1. Set up your category field: First, make sure you have a category field associated with each project in your collection. This field can be a single or multi-reference field, depending on whether a project can have multiple categories.

2. Create the category buttons: In your Webflow project, navigate to the page where you want to display the list of projects. Add a div block above the list of projects and insert buttons for each category you want to filter by. Give each button a unique class name.

3. Add custom code: Webflow does not have a built-in feature for filtering content by category, so you'll need to use custom code. Go to your project settings and click on the "Custom Code" tab. In the "Head Code" section, add the following code:

<script>  $(document).ready(function() {    $(".category-button").click(function() {      var category = $(this).data("category");            if (category === "all") {        $(".project-item").show();      } else {        $(".project-item").hide().filter(function() {          return $(this).data("categories").indexOf(category) > -1;        }).show();      }    });  });</script>

1. Set up interactions: In the Webflow Designer, select each category button and add an interaction. Set the trigger to "Click" and choose the appropriate target element(s) to fade out or toggle hide/show.

2. Connect the buttons to the code: Select each category button and set the "data-category" attribute to match the category value you set in your collection for each project.

3. Assign classes to project items: For each project item in your collection, assign a class name (e.g., "project-item") and set the "data-categories" attribute to an array of category values associated with that item.

By following these steps, you'll be able to filter the list of projects on your Webflow page by category using the top buttons.
