To integrate Findify Smart Collection follow these steps:

Getting started
Finding the Right Files to Edit
Adding the Code
Adding a Fallback

Step 1: Getting Started

To integrate smart-collections, you must first access your website template and asset files through an FTP client such as FileZilla using your SFTP login details. If you don’t already have FileZilla, please download FileZilla Client and access the website template of your current theme.

Step 2: Finding the Right Files to Edit

Once you access your website template through FileZilla, go to 'httpdocs' located on the bottom right box→ 'assets'.

Within assets, scroll down and click on ‘themes’ and continue to select the current theme of your website template and complete the following steps:
Once you open the folder of the current theme you are using, click on ‘templates’ → ‘cms’ → ‘category.template.html’

Step 3: Adding the Code

Then, open the ‘category.template.html’ file and update the file with the following code

<style>.findify-component-spinner,.findify-component-spinner:after{border-radius:50%;width:60px;height:60px}.findify-component-spinner{margin:60px auto 0!important;position:relative;-webkit-transform:translateZ(0);-ms-transform:translateZ(0);transform:translateZ(0);-webkit-animation:findify-component-spinner-animation .7s infinite cubic-bezier(.67,.35,.7,.8);animation:findify-component-spinner-animation .7s infinite cubic-bezier(.67,.35,.7,.8);-ms-transform-origin:50% 50%;-webkit-transform-origin:50% 50%;transform-origin:50% 50%;border-top:3px solid #eaeaea;border-right:3px solid #eaeaea;border-bottom:3px solid #eaeaea;border-left:3px solid #c6c6c6}@-webkit-keyframes findify-component-spinner-animation{0%{-webkit-transform:rotate(90deg);transform:rotate(90deg)}100%{-webkit-transform:rotate(450deg);transform:rotate(450deg)}}@keyframes findify-component-spinner-animation{0%{-webkit-transform:rotate(90deg);transform:rotate(90deg)}100%{-webkit-transform:rotate(450deg);transform:rotate(450deg)}}
</style>
<div data-findify="search">
	<div class="findify-component-spinner"></div>
  <div class="findify-fallback" style="display:none;">
    ..... default collection code goes here....
  </div>
</div>

After the update, the full 'category.template.html' may look like this:

<div class="content">
<div class="catalogue wk_catalogue">
<style>.findify-component-spinner,.findify-component-spinner:after{border-radius:50%;width:60px;height:60px}.findify-component-spinner{margin:60px auto 0!important;position:relative;-webkit-transform:translateZ(0);-ms-transform:translateZ(0);transform:translateZ(0);-webkit-animation:findify-component-spinner-animation .7s infinite cubic-bezier(.67,.35,.7,.8);animation:findify-component-spinner-animation .7s infinite cubic-bezier(.67,.35,.7,.8);-ms-transform-origin:50% 50%;-webkit-transform-origin:50% 50%;transform-origin:50% 50%;border-top:3px solid #eaeaea;border-right:3px solid #eaeaea;border-bottom:3px solid #eaeaea;border-left:3px solid #c6c6c6}@-webkit-keyframes findify-component-spinner-animation{0%{-webkit-transform:rotate(90deg);transform:rotate(90deg)}100%{-webkit-transform:rotate(450deg);transform:rotate(450deg)}}@keyframes findify-component-spinner-animation{0%{-webkit-transform:rotate(90deg);transform:rotate(90deg)}100%{-webkit-transform:rotate(450deg);transform:rotate(450deg)}}

Step 4: Adding a Fallback In the Unlikely Event of Downtime

Add a fallback for Findify Smart Collection which ensures that you have a custom-made or default collections of your own instead of Findify’s Smart Collections in the unlikely event of downtime.

You can easily set up a fallback by following these instructions Findify Collection Fallback.

In the fallback, adjust the default collection page to have 8-10 products instead of the whole page for page speed purposes. To do that, find a '[%THUMB_LIST type:'products' limit:'[@config:THUMB_LIMIT@]'%]' tag inside the fallback, and put limit: '8' or any other number.
