[Search] Category search should allow inline category headers

[nk9]

Both my category names and item titles were quite long, so stacking them next to each other resulted in a lot of wasted space. Solution: put the category headers inline, as differently-styled headers in the menu. But there is no clear way to do this in Semantic UI.

Here is the CSS solution I came up with on Stack Overflow. Ideally, this would be available as an option when initalizing the search widget. Something like:

{
    headerStyle: 'inline', // vs default of 'side' (to support LTR, vs 'left'?). Another possibility is 'none'.
}
