What is the process for creating classes of images for filtering in Webflow without using nested classes?
- Assign a base class to all images for styling and use either unique filter classes or custom data attributes (e.g., data-category) for category identification.
- Set up filter buttons with matching identifiers and use Webflow Interactions or libraries like MixitUp/Isotope to enable dynamic filtering.
To filter images by category in Webflow without relying on nested classes, you'll need to use unique class names or attributes and structure your content to enable filtering through Interactions or third-party libraries like MixitUp or Isotope.
1. Define Base Image Class
- Assign a shared base class (e.g.,
gallery-image) to all images for consistent styling. - Avoid using combo classes or nested classes for filtering purposes.
2. Use Custom Attributes or Unique Class Names per Category
Option A: Use custom attributes:
Select each image's container (like a
div.block) and add a custom attribute such asdata-category="nature"ordata-category="architecture".This allows JavaScript-based filter tools to target elements dynamically.
Option B: Use unique classes:
Add unique classes to each image wrapper (e.g.,
filter-nature,filter-people).Use these unique classes strictly for identification in filtering logic, not for styling.
3. Structure Your Filter Buttons
- Create buttons for each category (e.g., All, Nature, People).
- Assign each button a custom attribute like
data-filter="nature"or use relevantids or classes for identification.
4. Use Interactions (Optional for Simple Filters)
- If doing simple filters (like showing/hiding categories), use Webflow Interactions:
- On button click → apply an interaction that filters elements by showing/hiding them based on their class or
data-category.
5. Implement External Filtering Library (If Needed)
- For dynamic, animated filtering (e.g., MixitUp, Isotope.js), structure your elements correctly:
- All filterable items must share a container.
- Each item should include a custom attribute or a unique class to signal its category.
- The library reads those categories and handles sorting/filtering.
Summary
To create filterable image categories in Webflow without nested classes, use a shared base class for styling and assign either custom data attributes or unique filter classes to identify categories. Then use Webflow Interactions or a filtering library to achieve dynamic filtering behavior.
