How to make styled native filmstrip ads

In online advertising, a filmstrip is a vertical or portrait-aligned rectangular ad that cycles through several images, similar to a carousel. You can easily create this in AdButler using native ad templates and native ad items.

This feature requires the Enhanced Ads add-on. For more information on adding add-ons to your subscription, read How to change your subscription.

In this guide, we're going to create a simple filmstrip ad using a styled native ad template. This type of native template has only the HTML code. You must add the necessary JavaScript code and style element directly to your website to display the ad properly.

If you'd rather have all the necessary code (HTML, JavaScript and CSS) in the template, you should make your filmstrip ad using a custom native ad template instead. For more information on the differences between custom native ads and styled native ads, read About native ad templates.

Templates for custom native ad items are not compatible with styled native ad items, and vice-versa.

You will learn:

  1. How to create a template for a styled filmstrip ad. You can customize the sample code to fit your needs.
  2. How to create a styled filmstrip ad item once you have a styled filmstrip template.

How to create a styled filmstrip ad template

This template will require the user to provide the URLs to where the image creatives are hosted when creating the filmstrip ad item.

  1. Click Templates in the left navigation menu. The Templates section will appear.
  2. Click Native Ad Templates. The Native Ad Templates subsection will appear.
  3. Click Add Native Ad Template. The New Native Template window will appear.
  4. Click Styled. The New Native Ad Template page will appear.

Selecting a native template type

  1. Name the template then add an image URL variable for each image that will be in the ad. In our sample code, we have three image URL variables: ImageURL, ImageURL2, and ImageURL3.
For templates that have multiple variables such as this one, you can drag the icon on the far left of each variable field up or down to reorder your variables.

You can save variables and use them in other templates. After adding a variable, click on the three dots at the far right of the variable fields then click Save Variable as Template. To use a saved variable, click Add Saved Variable while creating a native template.
  1. Enter the code in the HTML Template (Styled) field, then click Save Changes.

Here's the code we used in our example:

<div class="filmstrip-container">
    <div class="slide">
        <a target="_blank" href="[TRACKING_LINK]">
            <img src="[%ImageURL%]">
    <div class="slide">
        <a target="_blank" href="[TRACKING_LINK]">
            <img src="[%ImageURL2%]">
    <div class="slide">
        <a target="_blank" href="[TRACKING_LINK]">
            <img src="[%ImageURL3%]">
    <a class="prev">
        <i class="fa fa-chevron-up"></i>
    <a class="next">
        <i class="fa fa-chevron-down"></i>
    <div class="filmstrip-close-button-container">
        <span class="filmstrip-close-button">×</span>

You can now use this template to create a styled filmstrip ad item.

How to create a styled filmstrip ad item

You can place images of any dimension within a filmstrip, but the container itself is 300 x 600 px. That means images with a 1:2 aspect ratio are best for filmstrips because they will fill the entire container, ensuring that only one image will be visible at a time, as shown in the example at the top of this guide.
  1. Go to the section of the relevant zone (Your AdButler > Publishers > Your Publisher > Your Zone) or campaign (Your AdButler > Advertisers > Your Advertiser > Your Campaign).
Styled native ad items can be assigned only to Native zones, with or without custom rendering enabled.
  1. Click Add Ad Item in the Ad Items table. The Add Ad Item window will appear.
  2. Click Native (Styled). The New Ad Item page will appear.

Creating a native (styled) ad item

  1. Select your filmstrip styled native template in the Template dropdown menu.
  2. Fill in the rest of the fields as needed, including the image URLs. If you entered a destination URL, you can test it by clicking Open Destination URL to the right of the field.
  3. Click Save Ad Item.

Creating a filmstrip styled native ad item in AdButler

At this point, you have finished setting up the ad item on the AdButler interface. You must now add the JavaScript and style element needed to display this ad properly directly to your website. Here's the sample code that we used in our example. You must replace the zone tags and zone class in the code with your own zone tags and zone class.
