When you have a bundle with multiple sections, you have the option to add conditional logic to the sections you have created.
Go to Bundles.
Select the bundle that you would like to edit.
Select Products, and scroll to Conditional Sections.
Setting up conditional logic affects how your products from each section interact with one another: it allows you to hide certain products from future sections if specific products have already been selected
To set a rule for when customers add certain products to their bundle section, you must first set the conditions under which this rule applies.
Under Conditional logic, select a condition from the following: ANY, ALL, NONE.
Select a section.
Select a product within this section to base the condition on.
In relation to the condition above, you can then hide products from being added to the bundle within a following section.
Under THEN HIDE, select Add a product.
Select a section for the rule.
Select a product to hide within this section under the condition set above.
