Problem

The Query Builder's user interface was composed using a combination of Vue 2 custom components and WiKit elements, such as Lookup. The WiKit design system is now on its deprecation path, as it has been superseded by Codex, the official Wikimedia design system. The utilization of WiKit components is not recommended, and they should be replaced in order to reduce maintenance costs and ensure consistency.

Solution

We have to replace WiKit's Lookup component by the Codex equivalent: cdx-lookup (Link to demo). This will take us a step closer to switching to the new design system and deprecating the old.

Acceptance criteria

• The WiKit Lookup component used in the Query Builder is replaced by its Codex equivalent
