KTUI Menu and Dropdown Stop Working in Blazor Server


Hello Metronic Support Team,

I am using the Metronic Tailwind version with KTUI in a Blazor Server project. I have encountered an issue where:

Sidebar menu toggles and dropdown menus work on the first click but stop responding afterwards.

This occurs even without navigating to a new page.

I suspect it is related to KTUI’s event listeners being detached when Blazor re-renders the DOM.

I have tried re-initializing KTMenu.init() and KTDropdown.init() using JavaScript after the first click and using a MutationObserver, but the issue persists.

Could you provide guidance or a recommended approach to make KTUI components fully compatible with Blazor Server’s lifecycle? Specifically, I need all menus, dropdowns, and toggles to remain functional after any Blazor re-render.

Thank you for your assistance.

Best regards,

Hi,

We have double-checked this issue in the latest version, and the menus and dropdowns are working as expected.

Could you please provide specific steps to reproduce the problem?
