How can MixItUp jQuery plugin be used to filter dynamic collections in Webflow, allowing for automatic appearance of new categories and items in the filters and content?

To use the MixItUp jQuery plugin to filter Webflow CMS (Collection List) content dynamically, including auto-generated filters for CMS categories or tags, you need to integrate MixItUp with Webflow’s dynamic data. Here’s how:

1. Understand the Goal

• You want to enable dynamic filtering (via MixItUp) of a Collection List in Webflow.
• The filters (e.g., buttons or tabs) should auto-update based on CMS data (like categories or tags).
• This requires custom attributes on dynamic items and auto-generated buttons for filtering.

2. Structure Your CMS

• Create two Collections:
• A main Content Collection (e.g., Blog Posts or Portfolio Projects).
• A related Category or Tag Collection (e.g., via a Reference or Multi-Reference field).
• This lets you relate posts/items to multiple categories if needed.

3. Design the Filter Buttons

• Add a Collection List on your page that pulls from the Category Collection.
• Within it, create buttons or links that represent each category.
• On each button, add an attribute like data-filter=".category-slug" where category-slug is a unique class matching the category.

4. Assign Filter Classes to Items

• In your main Collection List (e.g., blog posts), wrap each item in a <div> with mix class (required by MixItUp).
• Add a dynamic class to each item based on its category. For example:
• Use a Bound Text Field or custom attribute to add category-slug as a class to the wrapper div.
• Final classes should look like: mix category-design category-branding.

5. Include MixItUp Script

• Add MixItUp via CDN in your Page Settings > Before tag:
• Example: <script src="https://cdn.jsdelivr.net/npm/mixitup@3/dist/mixitup.min.js"></script>
• Add a second script to initialize MixItUp, like this:
• Example: <script>var mixer = mixitup('.mix-container');</script>
• Ensure .mix-container is the class of the parent wrapper around all mix items (your Collection List wrapper).

6. Handle Dynamic Filters

• Make sure your category buttons pull their data from the CMS and use the category slug for both:
• The button label (for the user).
• The data-filter attribute and matching class on items.

7. Optional Enhancements

• Add a button with data-filter="all" that resets filters.
• Use Webflow CMS Bindings to inject the slug dynamically:
• Button: data-filter=".w-dyn-bind:slug"
• Item: assign that same slug as a class.

Summary

To filter Webflow CMS collections dynamically with MixItUp:

• Use two Collection Lists: one for categories (filters), one for items.
• Dynamically assign filtering classes and data-filter attributes using CMS fields.
• Initialize MixItUp on the container of your Collection List.
• This setup ensures any new categories or items added in the CMS automatically update the filters and filtered content.
