For an alternative to the dropdown container widget, Mendix offers a few supported options:
Navigation Tree Widget: This widget can be adapted for a dropdown-style menu in the navigation bar. It’s highly customizable for displaying dynamic lists, including task lists, with custom icons and hierarchies.
List View with Dynamic Data Source: Embed a list view directly into a page or navigation structure and filter it based on conditions such as assigned tasks. You can style the list view to match dropdown behavior and trigger visibility through microflows or nanoflows.
Sidebar Layout or Pop-Up with Conditional Visibility: Create a sidebar or pop-up with task lists that show dynamically based on user roles or specific data. Use microflows or JavaScript snippets to mimic a dropdown action.
If you need further customization, you might also consider building a custom Mendix widget that meets all your specific requirements while still being fully supported.
