How can I create a multi-select filter in Webflow for custom dynamic filters, including code examples and a video tutorial? I have already implemented a custom dynamic filter using this forum (), but I want to allow users to make multiple selections for content filtering. Any guidance or assistance would be greatly appreciated. Best regards, Tony

You're trying to enhance your custom dynamic filter in Webflow by enabling multi-select functionality—ideal for filtering CMS content by multiple categories, tags, etc.

To do this, you’ll need custom JavaScript/jQuery along with checkbox inputs tied to CMS filter logic.

1. Add Checkbox Inputs for Filters

• In your Webflow project, go to the page containing your CMS list.
• Add a Collection List that references your filter options (e.g., categories or tags).
• Inside that list, insert a checkbox input (input type="checkbox") and give it a class like filter-checkbox.
• Also, add a data-filter attribute to the checkbox and bind it to the filter value (e.g., tag slug or category name).

Example:

• Checkbox class: filter-checkbox
• data-filter="business" (Set dynamically using a text field in the CMS)

2. Assign Classes and IDs to Key Elements

Ensure these elements use consistent naming:

• CMS wrapper (e.g., the div that contains all CMS items): #cms-wrapper
• CMS items (the individual cards or rows): cms-item
• Each item should include a hidden or visible element with the relevant filter terms, using a class like .tags or .categories.

Example:

• Each item includes <div class="categories">business marketing</div>

3. Add JavaScript for Multi-Select Filtering

Paste the following script just before the closing </body> tag in Page Settings -> Before tag:

Key behavior: It listens to checkbox changes, collects selected filters, and hides/shows CMS items accordingly.

<script>  document.addEventListener("DOMContentLoaded", function () {    const checkboxes = document.querySelectorAll(".filter-checkbox");    const cmsItems = document.querySelectorAll(".cms-item");    checkboxes.forEach((chk) =>      chk.addEventListener("change", function () {        const selectedFilters = Array.from(checkboxes)          .filter((box) => box.checked)          .map((box) => box.getAttribute("data-filter").toLowerCase());        cmsItems.forEach((item) => {          const categoryText = item.querySelector(".categories").innerText.toLowerCase();          const hasMatch =            selectedFilters.length === 0 ||            selectedFilters.some((filter) => categoryText.includes(filter));          item.style.display = hasMatch ? "block" : "none";        });      })    );  });</script>

4. Optional Enhancements

• Add a "Clear All" button that resets all checkboxes and shows all items.
• Style the checkboxes using Webflow’s native styling tools for better UI.
• Apply loading="lazy" to images inside list items for better performance.

5. Example Video Tutorial

While Webflow doesn’t have built-in multi-select filtering yet, this video tutorial shows how to implement a multi-select filter with checkboxes and CMS content using the method outlined above:

Finsweet's Attributes solution can also be used if you want to avoid custom code.

Summary

To enable multi-select filtering in Webflow:

• Add checkbox inputs with data-filter attributes
• Use JavaScript to detect selected filters
• Loop through CMS items and show/hide based on checkbox values
• Optionally, use video tutorials by Finsweet for a visual guide

This makes your dynamic filters much more powerful and user-friendly.
