<h3>Tabs</h3>

<h4>A collection of data that is associated with the separation content but belongs to a different category.</h4>

<p>Tab components are designed in the form of templates, and this component is used by adding <code>TabItem</code> subcomponents to the <code>tabItems</code> in the template</p>

<Tips>
    <p>
        <code>Tab</code> components are generally used in two ways:
        <ul class="ul-demo mb-3">
            <li>Split as data</li>
            <li>Page navigation</li>
        </ul>
        <div>The default behavior of this component is data segmentation,Clicking on the <code>TabItem</code> title does not navigate, and if you need to navigate the address bar, set the <code>ClickTabToNavigation</code> property to <code>true</code>，When you click on the <code>TabItem</code> title, the address bar redirects navigation, mostly for the background management system to be used in conjunction with the <code>Menu</code> components，The actual combat can refer to the <code>multi-label</code> mode in the <a href='layout-page' target='_blank'>background template simulator</a>,  When you have <code>Razor Component</code> in the additional Assemblies, set the <code>AdditionalAssemblies</code> property value correctly so that the route within the label component is resolved correctly, and the relevant documentation <a href='https://docs.microsoft.com/zh-cn/aspnet/core/blazor/fundamentals/routing?WT.mc_id-DT-MVP-5004174-view-aspnetcore-3.1-route-to-components-from-multiple-assemblies' target='_blank'>[Portal]</a></div>
    </p>
    <p>This component adapts to width height, etc., and scroll arrows can appear left and right or up and down when appropriate</p>
</Tips>

<p>
    <b>Set additional information during tab navigation</b>
</p>

<ul class="ul-demo">
    <li>Tab properties can be set when navigating using the built-in extension method <code>Navigator.NavigateTo("provider", "url", "text", "icon", "closable")</code></li>
    <li>Setting <code>@attribute [TabItemOption(Text = "LayoutPage", Icon = "fa-solid fa-font-awesome")]</code> in <code>razor</code> page</li>
</ul>
