Can I test the app in unpublished theme?
Currently, in order to hide Bundles and preview them before putting them live in your shop you have to edit two settings by doing the following:
- Go to the Bundler app > Settings > Bundle widget settings > "Show bundles on product pages" (check-box) needs to be turned OFF. This setting will prevent the app from showing your bundle widgets on product pages automatically.
- Next you must scroll down to Discount modes > and select the "Only if products were added to the cart from the bundle widget" option.
- Finally you must go to your bundle and get the landing page URL by doing the following: go to the Bundles tab > click on the desired bundle > on the top right corner you will see a button "Get landing page URL" > copy the URL.

When you click on it, you are going to see your test bundle and your customers will not be able to (unless you give them this link). Just make sure that when you want to display the bundles, you go back and change the settings as they were.

Another option would be to go to Bundler app > Settings > Enable in online shop and disable the automatic injection of widgets in your live shop by adding your store URL (or domain) in the "Disable automatic injection of widgets on specific urls" box. Note that this will disable the widgets on all pages that contain the domain you added to this field, essentially disabling them in your whole store.
Save settings and then go to Online store > at the theme you want to tests choose Actions > Preview. On the bottom of the page a pop-up will appear with a box Share preview, click on the box and copy and paste the URL into your browser. You are now previewing your shop and you can check and see how the bundle widgets look in your new theme.
