As an example let’s say you want to show a main list of e.g. projects, and upon clicking on a specific project, you want to display this project’s details, including this project’s associated tasks. Here’s how you can do it using Airtable data source as an example.

As soon as you add the Tasks list to the project's details page, you'll see that the Projects table's fields will start appearing inside Conditional Filters of the Tasks list block.

Using this, we can now set a condition to filter the Tasks list to show only the tasks that are associated with the project that's currently opened in the page. The condition will be set as shown below.

So, only the tasks for which the value in the Project column corresponds to the current project's Name will be shown.

Let's check how that works for the Ad Campaign project that includes two tasks (assigned to steven@softr.io and joanne@softr.io).

That's it. Now, each project details page will also show all the tasks associated to it.
