## Summary Throughout Zabbix we did not have a uniform UI - some drop-down were using `Select` others `Combobox` others a custom one that we created. Some had placeholders and others did not. This PR aims to standardize our Zabbix UI across our query, variable and config editors ## Detailed summary - Migrate from `Select` to `Combobox` -> `Select` component is deprecated - Migrate from `HorizontalGroup` to `Stack` -> `HorizontalGroup` is also deprecated - Remove use of "custom" dropdown `MetricPickerMenu` in favor of `Combobox` ensuring uniformity across our drop-down and removing maintenance overhead for us down the line - Standardize placeholders across all inputs <img width="630" height="243" alt="Screenshot 2025-12-17 at 1 13 45 PM" src="https://github.com/user-attachments/assets/9382057e-b443-4474-a9c8-850086d7f3d4" /> <img width="691" height="256" alt="Screenshot 2025-12-17 at 1 14 05 PM" src="https://github.com/user-attachments/assets/a05ff2af-8603-4752-8d12-337dc381c0fd" /> ## Why To have a clean and standard UI and remove use of UI deprecated packages. ## How to test - Query Editor: - By creating a new query in a dashboard or Explore and interacting with all the different query types and drop-downs - All drop-downs should be searchable and have placeholders - Config Editor: - By going to a datasource and ensuring that the dropdown for Datasource (when DB connection is enabled) and Auth type are responsive and working as expected) Fixes: https://github.com/orgs/grafana/projects/457/views/40?pane=issue&itemId=3740545830&issue=grafana%7Coss-big-tent-squad%7C139
