Bubble's filtering capabilities are a crucial part of building powerful and user-friendly web applications. In this video, we're diving into the difference between using "intersect with" and "contains list" filters in Bubble. Understanding these advanced filtering techniques will level up your Bubble skills and help you create more dynamic, data-driven apps.

Understanding "Intersect With" Filter in Bubble

The "intersect with" filter in Bubble checks if any items in a list match the specified criteria. It's incredibly useful for showing related or recommended data based on a user's preferences or categories.

Here's how to implement an "intersect with" filter in Bubble:

1. Set up your data types with the necessary fields (e.g., categories as a list field)
2. Create a search query with an "advanced filter"
3. Use the "intersect with" operator to compare the list fields
4. Specify the criteria for the intersection (e.g., greater than zero)

By using "intersect with," you can create powerful recommendations and show users content that aligns with their interests.

Exploring "Contains List" Filter in Bubble

The "contains list" filter in Bubble is perfect for creating browse pages with category filters. It checks if a list field contains all the items specified in another list.

To implement a "contains list" filter in Bubble, follow these steps:

1. Set up your data types with the necessary list fields
2. Create a page with a repeating group to display the filtered results
3. Add category filters using checkboxes or multi-select dropdowns
4. Use a custom state to store the selected categories
5. Apply a "contains list" filter to your repeating group's data source, comparing the list field with the custom state

With "contains list," you can create intuitive browse pages that allow users to filter results based on multiple categories.

Advanced Filtering Techniques in Bubble

Combining "intersect with" and "contains list" filters can take your Bubble app to the next level. You can create dynamic, personalized experiences by leveraging custom states and applying these filters in various parts of your app, such as dashboards and browse pages.

Some best practices for optimizing Bubble filter performance include:

• Indexing the fields you frequently use for filtering
• Limiting the number of items displayed in repeating groups
• Using efficient data structures and minimizing unnecessary API calls

Real-world Examples of Bubble Filtering

At No Code MBA, we've implemented both "intersect with" and "contains list" filters in our web application. On the dashboard, we use "intersect with" to show recommended courses and projects based on the user's selected categories. In the browse page, we use "contains list" to allow users to filter courses and projects by multiple categories simultaneously.

By applying these filtering techniques, we've created a more engaging and personalized experience for our users, helping them find the content that matters most to them.
