The sidebar for each page contains a link, which will take panel users to the corresponding page. Sometimes it makes sense to reroute this link or hide it entirely.
In Kirby it's often useful to add subpages as data providers instead of real pages. A typical example would be a one-pager with subpages for each section or a contact page with multiple addresses, which are fed by subpages. In such a case the preview link should lead to the parent page and not to the subpage.
For scenarios like this you have three available options to reroute the preview link:
The preview link will lead to the parent page.
…
preview: parent
…
The preview link will lead to the first subpage of the current page.
…
preview: first-child
…
The preview link will lead to the last subpage of the current page.
…
preview: last-child
…
The preview link can also be switched off entirely. In this case it will not be shown in the sidebar at all.
…
preview: false
…
By default pages can be deleted in the panel. In some cases you may want to protect important pages from deletion.
This setting will prevent panel users from deleting pages that use this blueprint:
…
deletable: false
…
Even when deleting is enabled, a page with subpages cannot be deleted. You have to delete its subpages first.
