When to use max modal


Use max modal when merchants need to complete a focused task, where leveraging the full viewport improves the user experience.

The following are some example use cases:

  • Complex editing experiences, such as an editor for creating newsletter content
  • Immersive experiences, such as an editor for cropping and modifying images
  • Previews, such as an app that adds elements to a product page and enables merchants to preview changes

Behavior

Anchor link to section titled "Behavior"
Max modal launches only after merchants interact with a button that indicates the entire canvas will be used.
A modal header with a secondary button labeled "Change puzzle template" and a primary button labeled "Save".

Must Do

Primary navigation for the app should be shown in the top bar of the modal and the primary actions must not be duplicated. This applies to developers using the latest version of App Bridge.
A dialog box that reads "Your template has unsaved changes. Changes will be lost if you leave without saving". There is a primary button that's labeled "Save Changes" and a secondary button that's labeled "Leave without saving".

Must Do

If there are unsaved changes, prompt merchants to save before exiting full-screen mode.
A modal with the title "Are you sure you want to exit?" and text "You're about to leave the template editor and go back to the Puzzlify home page.". The modal has a secondary button with the label "No, I want to stay" and a primary button with the label "Yes, I"m sure".

Do Not

Don’t unnecessarily interrupt a merchant’s workflow when exiting modal.

Do Not App Store Requirement

Your app must not launch full-screen or the max modal from the app nav. Instead, they must launch from the app body. This is an app store requirement.
A max modal that contains a fullscreen bar.

Do Not New

Don't use the FullscreenBar within a max modal, as it results in a confusing merchant experience with redundant mechanisms to dismiss the modal.

Admin UI extensions

Use admin UI extensions to integrate more deeply with the Shopify admin and create seamless merchant workflows.

Choose from the following extensions:

  1. Admin block
  2. Admin action
  3. Admin link
  4. Bulk action

Additional admin extensions are available for more specific use cases.

Do Not App Store Requirement

The extension can't be used to display promotions or advertisements. This includes promoting your app, related apps, or requesting app reviews. This is an app store requirement.

Hovering over the app attribution indicator reveals the full app name and color logo.
The app attribution component displays your app's logo and extension name as it displays in the Shopify App Store.

When to use admin blocks

Anchor link to section titled "When to use admin blocks"

Use admin block extensions to offer your app’s functionality or data in the context of a resource detail page. Merchants have the option to add your app block to a page, and arrange it in the page layout.

App blocks can be embedded into Product, Order, or Customer detail pages using these extension targets.

Guidelines indicate the maximum height of an app block.

Must Do

Contents must be less than 600px in height, to avoid overly tall app blocks. If necessary, implement pagination to ensure that this requirement is met.
A simple form with several input fields.

Must Do

Input fields must be visible at all times. If necessary, app blocks should trigger app actions to ensure that this requirement is met.
An example of an app block featuring an empty state and a non-empty state.

Must Do

Your block must have an empty state that informs merchants about what your app block does. For example, it should tell merchants what data will display in the block.
A simple app block form with the Shopify contextual save bar visible. The bar indicates that there are unsaved changes, and includes buttons to discard or save changes.

Tip

Inputs in your block can work with the contextual save bar by using the Form component, which provides merchants with a familiar save and validation experience.

When to use admin actions

Anchor link to section titled "When to use admin actions"

Use admin action extensions to offer merchants quick access to common actions that they might do with your app. Because apps can add an unlimited number of admin actions, use discrete actions for discrete purposes.

App actions can be targeted to these extension targets.

Learn more about admin actions.

Must Do

Don't allow action content to exceed 1200px and don't use more than two steps of pagination. Otherwise, your app can be difficult to navigate.

When to use admin links and bulk actions

Anchor link to section titled "When to use admin links and bulk actions"

If your content doesn't fit well within the format of the block or action, then use an admin link or bulk action instead. If an interaction is complex, such as one that requires more screen space, then routing merchants into your app is a better experience.

Examples include a multi-step process, a very long form with multiple dynamic sections, or a complex editor with several columns.

Do Not

Don't duplicate the content of your admin blocks and admin actions. Differentiating the functionality and value of your blocks and actions helps merchants understand which extensions to use and when.
