You will have values for parameters `category == main`, `id == 0005`. You can use these values by applying `{{HttpRequest.category}}` and `{{HttpRequest.id}}` in:

* [Components](/template-system/basics-of-template-system/templating-techniques-for-web-pages.md#url-parameters) on the page
* [API-endpoint](/api-integrations/api-endpoints-security-layer.md) filters

Additionally, you can set up a custom layout for each of these subpages.

You can configure a custom layout for each subpage or use the default one. To navigate between pages and subpages, simply use the [Link Button component](/web-pages/components/link-button.md).

[Cards](/web-pages/components/legacy-components/cards.md#purposes-of-the-component) and [Table](/web-pages/components/table.md#purposes-of-the-component) components have an option to open objects in subpages:
