I am trying to put in a panel bar that is collapsed by default. I took the demo and changed the expanded value to false.

<kendo-panelbar name="project">

<items>

<panelbar-item text="Storage" expanded="false">

<items>

<panelbar-item text="Wall Shelving"></panelbar-item>

<panelbar-item text="Floor Shelving"></panelbar-item>

<panelbar-item text="Kids Storag"></panelbar-item>

</items>

</panelbar-item>

</items>

</kendo-panelbar>

The panel bar items are collapsed but the icon is set to "k-i-arrow-60-up" so it looks like it can still be collapsed.

I am also wanting to put content other than <panelbar-item> in there, so I was going to use the <content> tag instead f the <items> tag an then put a treeview in there. When I use the <content> tag, the content is always show, so I must be using this incorrectly. I know I can do it with the html helpers, but I like how the tag helpers look. Can I still do this with the tag helpers?

Hello Johannes,

The behavior with the incorrect arrow being displayed when the parent item is collapsed appears to be a bug specifically of the the tag helper. I will investigate it further and most likely will log it for fixing.

As for the content of the item being always visible, this is expected. The item's content is a way to display more information or to customize the item. The PanelBar collapses and expands only child items, whereas the content is part of the item itself. It is something like the item's text, or more like an addition to the item's text, and it is always visible. So if you want to be able to expand (show) and collapse (hide) some content, it must be added to a child of a parent item.
