Please note that the display direction for the bundles that are placed via the "Gempages" is "Horizontal" by default since it's linked to the display direction of the "Bundles Page".
If you want to set the display direction for the bundles that are placed via the "Gempages" to "Vertical" like the display direction of the bundles in the "Included product pages", you should set the display direction of the "Bundles page" to "Vertical" via Fast Bundle admin > Customization > Design > Additional customization > Bundles page layout > Vertical
In the Gempages editor, you can add a "liquid" section.
Then, right-click and choose "Edit code".
List of HTML Codes:
Now you use the codes below for showing the bundles based on your need.
1- Insert all your bundles at once
Showing all of the bundles that you've made with Fast Bundle. (Except the Frequently Bought Together bundle).
This will work the same as the "Bundles page" in Fast Bundle.
<div class="rbrFastBundlePage"></div>
2- Insert Relating bundles to a specific product page
Showing all of the bundles that are relevant to a product on that product's page.
Fast Bundle will detect the product automatically and its related bundles. (Except for the Frequently Bought Together bundle).
<div class="rbrProductBundlePosition"></div>
This code can work only if inserted in a product page that has bundles.
3- Showing a bundle anywhere that you wish. (Except the Frequently Bought Together bundle)
You can use this code to add any specific bundle on any page you like. This doesn't include FBT bundles. Because they can only be shown on the main product pages.
<div class="rbrFastBundlePage" bundle-ids="BUNDLE ID"></div>
You can copy the BUNDLE ID from the top of the Edit Bundle page using the "Copy Bundle ID" button, or you can find it in "More Displays" under "Embed the bundle anywhere on your theme"
4- Only Volume discounts relating to a product page
When put on a product page, it'll show all of the volume discount bundles that are related to that product. Using this, you can now adjust the position of your volume discount bundles separately from other bundles on a product page.
<div class="rbrVolumeContainer"></div>
5- Insert FBT
Showing the Frequently bought together bundles that a product is their main product on its product page. (The bundle won't show on the offered product pages)
<div class="rbrFBTPosition"></div>
This code can work only if inserted in the "main product" page for FBT.
