#each_content_type(&block) ⇒ Object

Iterates over the content types with the following rules

  • content types are ordered by the updated_at date (DESC)

  • each content type has its own submenu if saved recently

  • if there are more than ui.max_content_types content types, the extra ones go under “…”

  • if a content type is selected and it is part of the extra content types, then it will be moved to the first position in the displayed list (with its own submenu)

Parameters:

  • block (Block) —

    The statements responsible to display the menu item from a content type or a list of content types

#entry_label(content_type, entry) ⇒ String

Renders the label of a content type entry. If no raw_item_template filled in the content type, it just calls the _label method of the entry (based on the label_field_id). Otherwise, it parses and renders the liquid template.

Parameters:

  • content_type (ContentType) —

    The content type for better performance

  • entry (ContentEntry) —

    The entry we want to display the label

Returns:

  • (String) —

    The label of the content type entry
