simple_sitemap_page_manager
The module allows the integration of simple_sitemap with panel pages, adding a new tab in the sitemap settings in the CMS, where all panel pages that are configured to be indexed in the sitemap will be listed.
In the settings of each panel page, in the general tab, the configuration will be added so that the user can choose if he wants that panel page to be indexed or not, and if so, he has the option to choose the priority and the change frequency.
In the case of panel pages, we will also take into account the language conditions that are set on the page access tab. If you have a condition, only the defined languages will be indexed in the sitemap, as they are the only ones accessible to the end user. If you don't have a language condition, all languages available on the site will be listed, as they will all be accessible to the end user.
