=== Background goal
While working on {T350037} we learned that is currently not possible to open a menu when people focus the [[ https://doc.wikimedia.org/codex/main/components/demos/lookup.html#default | Lookup ]].
During research we learned that there's an educational opportunity to proactively display suggested or recommended results when people focus a lookup field (based on the current context).
In the specific case of Wikifunctions, when people focus a lookup field that is used for the input type of a function, we could open the menu with the most used types for function inputs.

### User stories
//add at least one user story//
### Design spec

### Guidelines documentation
| Doc with Guidelines to include in Codex |
### Open questions
[x] Do we want to implement this as a base behavior for Lookup? - No, this will affect the Lookup just if an initial list of menu items is passed into the Lookup. In this case, it will open the menu on `focus`, and keep the menu open when the input is cleared.
