### Problem to solve: Making keyboard navigation faster.
The dropdown has listed some static options at the very top. This is useful when clicked, but when searching you have to press down (arrow down key) through all of them before you reach the search result.

In this example you have to press the down arrow key 3 times and then enter.

### Target audience
This is for every one who searches in the boards or lists.
<!--- For whom are we doing this? Include either a persona from https://design.gitlab.com/#/getting-started/personas or define a specific company role. e.a. "Release Manager" or "Security Analyst" -->
## Proposal
<!--- How are we going to solve the problem? -->
Remove _all_ dropdown options that don't match the typed query. For example, in this screenshot "Any" and "All" shouldn't appear because neither option matches "review."

### What does success look like, and how can we measure that?
Select the search result with as few key strokes as possible.
