Overview

Mobile Slideouts are single-step overlays that appear over part of your mobile apps screen. Unlike multi-screen Carousels that take over the entire display, Slideouts offer a lighter-touch way to communicate with users without disrupting their context completely. They’re perfect for highlighting a new feature, prompting an action, or providing important updates in a subtle yet effective format.
Slideouts are easy to build, and a fully customizable code is required.

Use Cases

  • Share time-sensitive announcements without taking over the whole screen.
  • Encourage completion of key actions (like verifying email or enabling notifications).
  • Communicate important alerts or policy updates in a less intrusive way.

Prerequisite

To start showing Mobile Slideouts to your end users, you’ll need to install the Userpilot script in your mobile application. Feel free to share the installation instructions with your engineering team, or reach out to our support team at support@userpilot.com if you encounter any issues during installation.

How to Create a Slideout

Go to Engagement > Mobile in the navbar and click Create Content. Navbar (1).png empty state (1).png Select Slideout as your content type. Screenshot 2025-07-09 at 19.37.27.png Choose to start from scratch or pick from a template. For this example, we’ll start from scratch, name your Slideout and select a folder to organize it in the Mobile Content Overview table. Screenshot 2025-07-09 at 19.38.49.png

Design your slideout

Unlike Carousels (which support multiple screens in a flow), a Slideout consists of just one screen, making the design simpler and more focused. You’ll find all design options in the Design tab:

General section

  • Themes: Choose a theme that matches your app’s overall style.
  • Font family: Select the font used in your slideout. By default, it uses the OS’s default font to ensure a familiar, consistent experience on all devices.
  • Position: Set the position of your content on the screen. You can choose:
    • Center: Align content to the center of the screen.
    • Bottom: Display the content at the bottom of the screen.
  • Layout: The layout defines the arrangement of the image, title, and text. For example, you can place an image at the top with a title and description below, or choose other configurations to match your needs.

Colors section

You can customize the background color of the slideout, as well as the title and text colors, by using a hex code. Screenshot 2025-07-09 at 19.49.28.png

Button section

Customize the button width, radius, background color, label color, and border colors using hex codes as needed. Button actions Determines what happens when the user taps the button:
  • Close
    • Simply closes the Slideout.
    • Best for informational messages or dismissible prompts.
  • Open Deep Link in the App
    • Opens a specific screen or section inside your app via a deep link.
    • Great for driving users directly to features or pages that match the message.
Ask your engineering team for the deep links to the screen you want users to open.Screenshot 2025-07-09 at 20.03.25.png
Screenshot 2025-07-09 at 19.52.25.png If you’d like to change the button label, simply click on the button in the mobile mockup within the Slideout editor, and you can edit it directly on the spot. Screenshot 2025-07-09 at 20.05.16.png
Key terms to knowDeep LinkA deep link is a special URL that doesn’t just open the app, but navigates directly to a specific screen or function inside it.For example, instead of opening your app’s home screen, it might open the Settings page, a product detail view.

Backdrop section

Use the toggle to control how much emphasis your message has, and customize the backdrop color and opacity to suit your design. Screenshot 2025-07-09 at 20.06.28.png

Dismiss section

Customize the dismiss button that allows users to close the slideout at any time. You can customize the appearance of the dismiss icon using the toggle to enable or disable it.
  • Color: Lets you choose the color of the dismiss icon (e.g., Automatic to match the theme or a custom color).
  • Icon Color: Enables you to specify the exact color of the dismiss icon using a hex code

Customize the slideout content

The content of each slideout section can be edited directly inline.

Image

You can update the image and alt text to support accessibility by clicking the edit icon, then adjust the Size & Space settings to customize its appearance.
  • Width and Height: set the dimensions of your image in pixels to control its size on the screen.
  • Fill: the image will expand to fill the available space, possibly cropping to maintain coverage. Best for full-width, impactful visuals.
  • Fit: the image will resize to fit within the space without cropping, maintaining its original aspect ratio. Best for clear, uncropped images.
  • Corner Radius: adjust the roundness of the image corners in pixels for a softer or more modern look.

Additional explanation of how Userpilot handles images with Fill and Fit options:Fill is like saying, I want this entire space covered, no matter what.When you choose Fill, Userpilot will stretch or squash the image to completely cover the width and height of the frame.
  • It doesn’t preserve the original aspect ratio, which means the image might end up looking distorted if it wasn’t designed for that shape.
  • Think of it like stretching a small sticker over a big box—you’ll cover every corner, but it might look a bit warped.
  • This option is great for abstract backgrounds or placeholder visuals where distortion isn’t a problem.
For example:
  • Your frame is 300×300.
  • Your image is 200×300.
  • Result? It’s stretched to 300×300, changing its proportions to fit perfectly in the space, even if it looks a little off.

Now, let’s talk about Fit. This option says, Show my image as it really is, no distortion allowed.When you choose Fit, Userpilot will scale the image proportionally so the entire thing is visible within the frame.
  • The aspect ratio is preserved, so the image keeps its original shape.
  • It might not fill the whole space, leaving empty areas (like letterboxing) on the sides or top and bottom.
  • This is perfect when you want users to see your logo, product image, or any visual that needs to look exactly right.
For example:
  • Your frame is 300×300.
  • Your image is 200×300.
  • Result? The image stays 200×300, perfectly centered, with 50pt padding on either side to fill the space evenly.

In short:
  • Choose Fill if you want to cover the entire space, even if that means distorting the image.
  • Choose Fit if you want to preserve your image’s original shape, even if there’s empty space around it.
Videos aren’t supported in Mobile slideouts at the moment, but you can include animated GIFs instead.
The following formatting options are supported for the header:
  • Headings: H1, H2, and H3.
  • Horizontal Alignment: Left, Center, and Right.
  • Link: Navigate your users to a specific URL. Userpilot will open the browser to display the link.
  • Personalization: Insert user or company properties to create a more personalized experience.

Text

The following formatting options are supported for the text:
  • Font Size: Set your font size in pixels. Userpilot will automatically convert it to the appropriate unit for mobile, adjusting to the device dimensions to ensure the text is readable.
  • Horizontal Alignment: Left, Center, or Right.
  • Font Style: Apply Bold or Italic styling.
  • Link: Direct users to a specific URL. Userpilot will open the browser to display the link.
  • Personalization: Insert user or company properties to create a more personalized experience.

Localization

You first need to activate the localization settings from the Settings page. For detailed instructions, follow the steps in this Localization document.
Userpilot lets you localize your mobile content to make it more relevant and accessible globally. Click on the Localization tab and start localizing your content based on the languages you’ve added. Screenshot 2025-07-09 at 20.38.48.png
Mobile localization only works when you pass the locale_codeattribute. Make sure you’re setting up localization for both web and mobile using the locale code, since the browser language won’t automatically work on mobile.Screenshot 2025-07-09 at 17.56.02 (1).png

Publish your slideout

Once you’ve designed your Mobile Sideout and localized the content, the next step is to configure the slideout settings and publish it to your end users.

Trigger

Define when the slideout should appear for users. Options include:
  • Start app session: Perfect for onboarding new users or welcoming them back with important updates as soon as they open the app.
  • Screen-Specific: Great for feature adoption, highlight a feature or guide users when they reach a specific screen in the app.
  • Event-Occurrence: Ideal for contextual help or upsell prompts, trigger the slideout when users complete an action like making a purchase or saving a setting.
  • Only-Manually: Best for advanced use where you want full control. For example, triggering a slideout from a custom button in the mobile app.
You can view the Only-Manually trigger code for both iOS and Android, and share it with your engineering team. They can integrate it into the app’s codebase to trigger the slideout whenever an end user interacts with the specific mobile app element containing the code.Screenshot 2025-07-09 at 20.40.02.png

Environment

Choose where this slideout should be triggered:
  • Staging Environment: For testing and QA.
  • Production Environment: For live, end-user experiences.

Operating System

Select which OS your slideout will appear on:
  • Any operating system: Both iOS and Android.
  • iOS: Target only Apple devices.
  • Android: Target only Android devices.

Audience

Define who should see your slideout:
  • All Users: Everyone identified user in Userpilot, and using the app.
  • Saved Segment: A pre-defined user segment.
  • Custom Conditions: Set specific rules to target users meeting chosen criteria.

Goal

Set a goal to measure how the slideout influences user behavior:
  • No Goal: No specific outcome tracked.
  • Perform an Action: Track if users complete a key action after seeing the slideout.

Frequency

Control how often users see the slideout:
  • Only Once: Show a single time per user.
  • Time Based Recurrence: Repeat after a set period.
  • Until The Goal Is Met: Would normally repeat until the defined goal is achieved.

Schedule your slideout

If you want to schedule your slideout to go live at a specific date and time, you can easily set that up after clicking the Publish button. Simply select the start date and time for when it should be live, and you can even choose when you’d like it to stop showing to users. Screenshot 2025-07-09 at 20.41.59.png
The publication time is based on your account’s time zone set in the General page, not the user’s local time.
And that’s it. Your Mobile Slideout is ready to publish.
