I am experiencing an issue with UI for Blazor's SplitButton. When I click on the dropdown arrow initially, it correctly expands the dropdown list area. However, while the dropdown list area is expanded, if I click the arrow again, it does not close it, leaving the dropdown list area expanded. The exact behavior appears to be that the dropdown collapses while the mouse is pressed down over the arrow button, but when the mouse is released, the dropdown list area expands again.

Reproduction: https://blazorrepl.telerik.com/QnlPPdvv50aUXSKO14.

The desired behavior is that the split button arrow would toggle the dropdown list between expanded and collapsed states.

How to add a separator item in the SplitButtonItems collection?

The screen reader cannot read the SplitButton elements inside the dropdown.

I'd like to be able to programmatically open/close the popup of the SplitButton. For example, open it on click of the main button.

I recently upgraded the target framework to .NET 7 and the UI for Blazor package to 3.7. With this configuration in my WASM app, it looks like the OnClick event for the child buttons is sometimes not fired. It happens occasionally and not for all child buttons.

Last working version: UI for Blazor 3.6.1. and .NET 6. You may revert to that configuration until the fix is live.

 

This will make it easier to have a dynamic list of options whose order can be preserved.

Otherwise, you need to use conditional markup (which puts newly made visible items at the end), or a @foreach over a descriptor model.
