In this article, you will see how you can add tabs on a nopCommerce admin side using a plugin. Let’s directly dive into the implementation part because I believe when developers search for this type of article, they are looking for solutions that will help them to learn or troubleshoot issues. The following are the steps to add a tab on the admin side using a plugin in nopCommerce 4.3. 

FindWidgetZone

 First, identify on which admin side page you want to add a tab. In this article, I am adding a tab on the admin order edit page. So, first I need to find the order edit page in the source code to check the WidgetZone of page. In this widget zone, we will return our new tab view page. I am finding a widget zone on ~PresentationNop.WebAreasAdminViewsOrderEdit.cshtml. The Widgetzone’s name is AdminWidgetZones.OrderDetailsBlock

FindWidgetZone

Add ViewComponent and WidgetZone Name

 To add a custom tab on the admin side I am using the existing nopCommerce NivoSlider plugin. First, go to the plugin file PluginsNop.Plugin.Widgets.NivoSliderNivoSliderPlugin.cs. If it’s a new plugin then make sure your plugin inherits IWidgetPlugin. Go to GetWidgetZones() method, and in that add the widget zone which you found on the order edit page; i.e. AdminWidgetZones.OrderDetailsBlock. Now GetWidgetZones() will look as follows:

Now we will add viewcomponentname in GetWidgetViewComponentName in the same file. We add viewcomponent name WidgetsAdminOrderDetails. This viewcomponent calls when we view the admin order edit page. And this view component will return the list of tabs that we want to add. 

Create ViewComponent and TabList and TabContent cshtml file

 Now we will create view component file WidgetsAdminOrderDetailsViewComponent.cs following is code. The file location will be Nop.Plugin.Widgets.NivoSliderComponentsWidgetsAdminOrderDetailsViewComponent.cs

Now we will create AdminOrderTabList.cshtml. In this file, we will provide a list of tabs with their tab content file. We will create this file at the following location: PluginsNop.Plugin.Widgets.NivoSliderViewsWidgetsAdminOrderDetailsAdminOrderTabList.cshtml. I am creating a new folder WidgetAdminOrderDetails under the view folder of the plugin. Following is AdminOrderTabList.cshtml file.

If you want to add multiple tabs in the order edit page, then replicate this code in the same file and provide different cshtml file locations for tab content. [Tips: I copied this content from order/ edit.cshtml file of nopcommerce.]

For tab content we specified /Plugins/Widgets.NivoSlider/Views/WidgetsAdminOrderDetails/_CustomTab.Order.cshtml. So, following is the content of _CustomTab.Order.cshtml file content. 

Now please make sure both .cshtml files are marked as copies as in the below screenshot. If you are using VSCode then you manually need to add this in a plugin.csproject file i.e(PluginsNop.Plugin.Widgets.NivoSliderNop.Plugin.Widgets.NivoSlider.csproj)

Now build a plugin and check the order edit page ( AdminOrderList -> Click on VIEW button) of nopCommerce. Following is the final result, as you can see the CustomTabTitle tab.

Following is a screenshot of the files which I added or changed to implement this functionality.

Your feedback and suggestions help me to improve this article. In this article, I didn’t explain the code very much because the main purpose of this article is to show complete steps to add custom tabs in admin nopCommerce using the plugin.
