Preparations

Create a new app
Add the following content items in the Root Collection:
- Placeholder for tablet
  - Type: Placeholder
  - Name: tablet
  - Title: Tablet
- Placeholder for phone
  - Type: Placeholder
  - Name: phone
  - Title: Phone
- Placeholder for browser
  - Type: Placeholder
  - Name: browser
  - Title: Browser
- Placeholder for the other content
  - Type: Placeholder
  - Name: any
  - Title: Any
Setup your Advanced Scripting (see below)

Advanced Scripting Settings

1. Exact naming

For the Root Collection:

// Executed once for every collection before the filtering of the items
function setupFilter(collection, environment) {
}

// Executed for once for every collection
function shouldShowCollection(collection, environment) {
    return true;
}

// Executed for every single content item
function shouldShowItem(contentItem, collection, environment) {
    if (contentItem.Name == "browser") {
        return environment.IsBrowser();
    } else if (contentItem.Name == "phone") {
        return environment.IsPhone();
    } else if (contentItem.Name == "tablet") {
        return environment.IsTablet();
    } else {
        return true;
    }
}

// Executed once for every collection after the filtering of the items
function teardownFilter(collection, environment) {
}

2. Non-exact naming

In reality, your Content Items will probably have other names (in order to differentiate) and then it's probably not a good idea to call them all phone, or tablet or browser. In reality, you'll probably work with a suffix, a prefix or a name containing one of the parameters mentioned above.

2.1. Using a prefix

If you want to add a prefix to your existing Name for your Content Item, then you need to use the following code:

// Executed once for every collection before the filtering of the items
function setupFilter(collection, environment) {
}

// Executed for once for every collection
function shouldShowCollection(collection, environment) {
    return true;
}

// Executed for every single content item
function shouldShowItem(contentItem, collection, environment) {
    if (contentItem.Name.startsWith("browser")) {
        return environment.IsBrowser();
    } else if (contentItem.Name.startsWith("phone")) {
        return environment.IsPhone();
    } else if (contentItem.Name.startsWith("tablet")) {
        return environment.IsTablet();
    } else {
        return true;
    }
}

// Executed once for every collection after the filtering of the items
function teardownFilter(collection, environment) {
}

The name of your Content Item should then be something like:

browser-contentitem01
phone-contentitem01
tablet-contentitem01

2.2. Using a suffix

If you want to add a suffix to your existing Name for your Content Item, then you need to use the following code:

// Executed once for every collection before the filtering of the items
function setupFilter(collection, environment) {
}

// Executed for once for every collection
function shouldShowCollection(collection, environment) {
    return true;
}

// Executed for every single content item
function shouldShowItem(contentItem, collection, environment) {
    if (contentItem.Name.endsWith("browser")) {
        return environment.IsBrowser();
    } else if (contentItem.Name.endsWith("phone")) {
        return environment.IsPhone();
    } else if (contentItem.Name.endsWith("tablet")) {
        return environment.IsTablet();
    } else {
        return true;
    }
}

// Executed once for every collection after the filtering of the items
function teardownFilter(collection, environment) {
}

The name of your Content Items should then be something like:

contentitem01-browser
contentitem01-phone
contentitem02-tablet
