Tree View item styling

[ianclough]

I'm looking for a way to add style to individual tree view items e.g. underlined text or maybe different coloured text. My application is similar to an IDE and I'm using a tree view to display a component hierarchy. I have an implementation that renders custom content within a FluentTreeItem but something more out of the box would be nice.

It would also be helpful to support a right click context menu per item.

The tree does not have support for right click menu.

Did you https://fluentui-blazor.net/TreeView#dynamictreegeneratio? You can use ItemTemplate to style your items

Thank you, I may be missing something, but can you individually style the items. In my case I want to apply red underlining to items in the tree view that have errors.

Yes, you can have conditional code in the ItemTemplate like in the example with the line between the span tags:

<ItemTemplate>
        @context.Text
        <span style="color: var(--accent-fill-rest); margin: 0 4px;">
            @(context.Items == null ? "" : $"[{context.Items.Count()}]")
        </span>
    </ItemTemplate>
