-You can configure what information all cards will display on their left side using the [`cardShape`](/api/config/booking-cardshape) property or the [`cardTemplate`](/api/config/booking-cardtemplate) property, which also allows customizing the appearance of each card's block.

-`cardTemplate` helps completely customize the appearance of a card by providing your own custom HTML. It gives full control over the card's layout, design and content.
-`cardShape` allows you only to modify the default template by hiding/showing fields.
-If both are applied, `cardTemplate` will override the `cardShape` settings.

-On the left side of each card the following data fields are displayed by default:
-- preview: card image
-- review: rating information with the number of rating stars (out of five) and the number of reviews
-- category: the subtitle of a card
-- title: the title of a card which is a specialist's name
-- subtitle: the subtitle of a card, for example, experience details
-- price: the price of the service
-- details: other details of a card
+### Hide or show card fields
-To hide any information block from cards' display, set the appropriate parameter value of the [`cardShape`](/api/config/booking-cardshape) property to **false**.
+Use [`cardShape`](/api/config/booking-cardshape) to control which fields appear on the left side of each card without changing the default layout.
-Example:
+The following fields appear on the left side of each card by default:
+- `preview` — card image
+- `review` — rating information including the number of stars (out of five) and the number of reviews
+- `category` — category name (e.g., a specialist's job)
+- `title` — card title (e.g., a specialist's name)
+- `subtitle` — card subtitle (e.g., experience details); hidden by default
+- `price` — service price
+- `details` — additional card details

+### Apply a custom card template
+
+Use [`cardTemplate`](/api/config/booking-cardtemplate) to apply a custom HTML template to the left side of each card.
-First, create a function that takes a card object and returns a string of HTML. To define a template, arrange card item properties into any HTML blocks with custom styles. In the example, `cardPreviewTemplate` returns HTML for a card that includes a preview image (card.preview), category (card.category), title (card.title), and price (card.price).
