# Sorting and Filtering Lists

If you want to make it so that your app only displays a particular subset of your data, you can create a data filter.

For example, let's take the app we've previously been working on, which allows you to browse vacation spots. Suppose you input all of your data into a Trips Collection with many Properties, one of which is a True/False criteria describing whether or not the trip is public. Let's say for your app, you only want to display trips that are public. You also want to sort the trips from low cost to high cost.

![Steps 4 and 5](/files/-Lihtriuk_VEm6KcKRLZ)

1. Insert a list
2. Select the database collection you want listed
3. Click 'Add another filter' to insert a custom filter
4. Select which Property you want the filter to depend on (in this case, Public)
5. Choose the condition of the Property that you want to filter for (True/False, Between, Includes, Excludes, etc)
6. Under Sorting select how you want to sort your list (in this example, Cost- Low to High)

&#x20;After filtering, only the trips that had been tagged as public showed up in the preview.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://help.adalo.com/component-basics/connecting-lists-and-forms-to-a-database/applying-filters-to-lists.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
