CMS Kit: Marked Item System

CMS kit provides a marking system to mark any kind of resource, like a blog post or a product, as a favorite, starred, flagged, or bookmarked.

Marked toggling component allows users to mark your items via pre-defined icons/emojis. Here how the marked toggling components may look like:

you can also customize the marking icons shown in the toggling components.

Enabling the Marked Item Feature

By default, CMS Kit features are disabled. Therefore, you need to enable the features you want, before starting to use it. You can use the Global Feature system to enable/disable CMS Kit features on development time. Alternatively, you can use the ABP Framework's Feature System to disable a CMS Kit feature on runtime.

Check the "How to Install" section of the CMS Kit Module documentation to see how to enable/disable CMS Kit features on development time.

Options

Marking system provides a simple approach to define your entity type with mark types like favorite or starred. For example, if you want to use the marking system for products, you need to define an entity type named product with the icon name.

CmsKitMarkedItemOptions can be configured in YourModule.cs, in the ConfigureServices method of your module. Example:

Configure<CmsKitMarkedItemOptions>(options =>
{
    options.EntityTypes.Add(
        new MarkedItemEntityTypeDefinition(
            "product",
            StandardMarkedItems.Favorite
            )
        );
});

CmsKitMarkedItemOptions properties:

• EntityTypes: List of defined entity types (CmsKitMarkedItemOptions) in the marking system.

MarkedItemEntityTypeDefinition properties:

• EntityType: Name of the entity type.
• IconName: The name of the icon.

The Marked Item widget

The marking system provides a toggle widget to allow users to add/remove the marks from an item. You can place the widget with the item as shown below:

@await Component.InvokeAsync(typeof (MarkedItemToggleViewComponent), new
{
    entityId = "...",
    entityType = "product",
    needsConfirmation = true // (optional)
})

• entityType was explained in the previous section.
• entityId should be the unique id of the product, in this example. If you have a Product entity, you can use its Id here.
• needsConfirmation An optional parameter to let the user confirm when removing the mark.

Connection string

This module uses CmsKit for the connection string name. If you don't define a connection string with this name, it fallbacks to the Default connection string.
