How can I make my sold-out variants unselectable?

To manage your sold-out variants of a product to be unselectable please follow these steps:

On your Fast Bundle admin panel, go to the "Setting" tab.

Then, click on the "Bundle settings" tab.

Activate the "Track Inventory" checkbox.

Choose "Don't display unavailable bundles" from the options. Then "Save" the changes.

.

!!! Note: Please pay attention that if all the variants of your product are sold out, a sold-out badge will display on your bundle. But if some variants of the product are sold-out, the variants won't be selectable on the variant selector of the bundle.
