# Additional Features

With this feature you have the possibility to add a Dropdown in the
Mainmenu for some Contenttypes. To activate set „showinmenu = true“ for
needed contenttypes in contenttypes settings.

Contenttypes with this additional Dropdown are automatically hidden in
the default Content Dropownmenu.

The idea behind this feature is to allow Quick access for related
contents.

## Dragndrop sorting in overview list

This feature enables dragndrop sorting for grouped content in overview
list and the relation view. It is not finished at the moment because it
needs an UpdateStatement in Backend.php. I will complete this feature
asap.

## Set default taxonomy option
To make it more easier get in comfort of the manual sorting this
feature enables the set of a default param in taxonomy.yml

So you can add for example under chapters configuration:
default: main

With this example every contenttype that uses chapters and has no
manually selected chapter, is preselected with the default chapter
„main“

It fixed the problem, that the Order field is not usable except a
chapter is selected.

Info: This default param feature just works for the behaves_like type
grouping which is relevant for sorting

View a Page or a contenttype directly with the preview button in
Menubar if something selected

If nothing is selected the default Button „View site“ appears.
