The Condition Layout app renders a component in your store when predefined conditions are met.

In the manifest.json file of your theme, add the Condition Layout app as a dependency:

You can now use all blocks exported by the condition-layout app. See the full list below:

Block name	Description
condition-layout.product	Defines the condition logic in the product context and the children blocks that will be rendered when the predefined conditions are met.
condition-layout.binding	Defines the condition logic in the current binding and the children blocks that will be rendered when the predefined conditions are met.
condition-layout.category	Defines the condition logic on the current category or department page and the children blocks that will be rendered when the predefined conditions are met.
condition-layout.telemarketing	Defines the condition logic in the user role (telemarketing) and the children blocks that will be rendered when the predefined conditions are met.

In the product theme template, add the condition-layout.product block as a child. For example:

Or the condition-layout.binding block. For example:

Or the condition-layout.category block. For example:

Never use condition-layout directly. Always use it with a context variant, such as condition-layout.product.

Now it is time to configure the condition-layout.product block!

Use the block props to define your layout condition. You can also declare blocks of your choice as children of condition-layout.product. These children blocks will be rendered if the condition is met.

For example:

Or for condition-layout.binding:

Or for condition-layout.category:

Or for condition-layout.telemarketing:

In the example above, whenever users interact with a product whose ID is equal to 12, the flex-layout.row#custom-pdp-layout-12 block is rendered. If users interact with a product whose ID is not equal to 12, the rendered block is flex-layout.row#default.

Prop name	Type	Description	Default value
conditions	object	List of desired conditions.	undefined
matchType	enum	Layout rendering criteria. Possible values are: all (all conditions must be met to render the layout), any (at least one of the conditions must be met to render the layout), or none (no conditions must be met to render the layout).	all
Then	block	Name of the block to be rendered if the conditions are met. If no value is defined, the blocks declared as children of condition-layout.product will be rendered instead.	undefined
Else	block	Name of the block to be rendered if the conditions are not met.	undefined

• conditions object:

Prop name	Type	Description	Default value
subject	string	Defines, based on the product context where the block is declared, which information is needed from the UI to validate the value chosen in the object prop. See below the possible values for this prop.	undefined
arguments	object	Defines the condition parameters. Note that the value of this prop varies depending on the value set for the subject prop. See below the table with the possible values for the subject prop and their expected arguments.	undefined
toBe	boolean	Determines whether the data fetched in the subject prop must meet the predefined conditions to render the new layout (true) or not (false).	true

Possible values for subject prop of the condition-layout.product block:

Subject	Description	Arguments
productId	Product IDs currently displayed on the UI.	{ id: string }
categoryId	Category IDs currently displayed on the UI.	{ id: string }
brandId	Brand IDs currently displayed on the UI.	{ id: string }
selectedItemId	ID of the item currently selected by the user.	{ id: string }
productClusters	List of product clusters currently displayed on the UI.	{ id: string }
categoryTree	List of categories currently displayed on the UI. Note: Only available on the Product Detail Page.	{ id: string }
specificationProperties	List of product specifications currently displayed on the UI.	{ name: string, value: string }. Note: value is an optional prop. If omitted, only the specification name (name) will be checked.
areAllVariationsSelected	Determines whether all product variations currently available on the UI were selected by the user (true) or not (false).	No arguments are expected.
isProductAvailable	Determines whether the product is available (true) or not (false).	No arguments are expected.
hasMoreSellersThan	Determines whether the number of sellers for a product is greater than the argument passed.	{ quantity: number }
hasBestPrice	Whether the product is being given a discount on its list price.	{ value: boolean } or no arguments.
sellerId	Whether any of the sellers of the product are included in the list of IDs passed.	{ ids: string[] }

Possible values for the subject prop of the condition-layout.binding block:

Subject	Description	Arguments
bindingId	ID of the desired store binding.	{ id: string }

Possible values for the subject prop of the condition-layout.category block:

Subject	Description	Arguments
category	Category IDs currently displayed on the UI.	{ ids: string[] }
department	Department IDs currently displayed on the UI.	{ ids: string[] }

Possible values for the subject prop of the condition-layout.telemarketing block:

Subject	Description	Arguments
impersonable	Value of the impersonation setting.	{ value: boolean }

The condition-layout.product block mainly uses the matchType and conditions props to respectively set the criteria and the conditions that blocks must meet to be rendered.

The conditions prop does not rely on any automatic grammar to define the desired conditions. Instead, it relies on its two props, namely subject and arguments, which together define which condition must be met by using an underlying data validation method (with specific arguments) based on the UI behavior.

Lastly, the matchType prop decides the necessary number of valid conditions for the layout rendering.

The Condition Layout merely establishes a logic to render other blocks. Therefore, the app does not have its own CSS handles for customization.

Instead, you should use the handles of the child blocks.
