Shoplift is the first A/B testing platform built specifically for Shopify, and the tight integration between the two platforms allows you to make edits to test variants directly from the Shopify Editor.
Once you've created a test draft, you can edit your new variant by clicking the 'Edit in Shopify' button from the test draft page. This will open the Shopify Theme Editor in a new tab where you can then make your edits.
The Theme Editor will automatically open to your variant template, so you don't need to worry about accidentally editing a live page on your website.
If you want to double-check that the template you're editing is in fact your variant template, you can confirm by simply looking at the template name presented in the sections sidebar (on the left) in the Theme Editor. The name will match the variant name on the right side of the test draft page in the Shoplift app.
When you edit your variant in the Shopify Editor, you will be working on an unpublished version of your template. All of your edits remain unpublished until you launch your test.
When you are finished editing your variant in the Shopify Editor, click 'Save.' Once your changes are saved, you can close the Shopify Editor tab in your browser and return to the Shoplift app to review your test before launching.
Always make sure you have saved your latest edits in Shopify before launching a test. Launching a test without saving your edits will result in your live site not representing the changes that were intended.
