Layers (OrchardCore.Layers)

The layers can be managed from the Design > Widgets page in the admin.

A layer has a name, a description and a rule in which you specify a condition to render the widgets that will be associated to this layer.

When you add a widget into a zone, you can select the associated Layer for which the widget will be displayed if the corresponding display rule is valid.

You can select the checkbox next to each layer in order to highlight the associated Widgets on the left.

In the rule, you can use a javascript function that will return a boolean.
Ex: The Always rule has the rule set to true.

Rules

Here are some available functions:

Function Description
isHomepage(): Boolean Returns true if the current request Url is the current homepage
isAnonymous(): Boolean Returns true if there is no authenticated user on the current request
isAuthenticated(): Boolean Returns true if there is an authenticated user on the current request
url(url: String): Boolean Returns true if the current url matches the provided url. Add a * to the end of the url parameter to match any url that start with
culture(name: String): Boolean Returns true if the current culture name or the current culture's parent name matches the name argument

You can add new functions by implementing an IGlobalMethodProvider. See Scripting

Zones

The zones that are listed can be set in the Design > Settings > Zones admin page.

You must have declared the corresponding zones as sections in your theme :

{% render_section "Header", required: false %}
@await RenderSectionAsync("Header", required: false)
