Restricting Types in a Folder

The Add new... menu has a choice for restricting the content types that can be added to the folder.

Restricting types available for adding to a folder is the simplest way to control content creation on a Plone web site. You may want to restrict content types if your site is going to be worked on by several people. In this way you can enforce good practices such as putting just images in the images folder.

First, select the last choice in the Add new... menu called Restrictions...:

There are three choices shown for restricting types in the folder:

The default choice, to use the setting of the parent folder. Having this as the default means that if you create a folder and restrict the types that can be added, any subfolders created in the folder will automatically carry the restrictions. The second choice, to allow the standard types to be added, is a way to reset to the default, unrestricted setting. The last choice allows selection from a list of available types:

Types listed under the Allowed types heading are those available on the web site. The default, as shown, is to allow all types. Allowed types may be toggled on and off for the folder.

Use of Secondary types allows a kind of more detailed control. For example, if it is preferred to store images in one folder, instead of scattering them in different folders on the web site -- a scheme that some people prefer -- an "Images" folder could be created with the allowed type set to the Image content type only. Likewise an "Company Events" folder could be created to hold only the Event content type. If left this way, content creators would be forced (or a single web site owner) to follow this strict scheme. Perhaps some flexibility is desired for images, though. By checking the Image content type under the Secondary types heading for the "Company Events" folder, images could be added if really needed, by using the More... submenu, which would appear when this mechanism is in place.

Some people prefer a heterogeneous mix of content across the web site, with no restrictions. Others prefer a more regimented approach, restricting types in one organizational scheme or another. Plone has the flexibility to accommodate a range of designs.
