Blazor Components

Some Blazor components I'm working on:

• Tree
• Tag Selector
• Page Panel

See running example: https://blazorcomponents.z6.web.core.windows.net/

Tree

<Tree 
    Nodes="Items" 
    SelectedNode="SelectedItem" 
    ChildSelector="@(item => item.Childs)">
    <TitleTemplate>@context.Text</TitleTemplate>
</Tree>

Client Dependencies

<link rel="stylesheet" href="_content/MW.Blazor.Tree/styles.css" />
