At the moment live search works by either setting something to hidden
or displayed. When the search term is empty, it sets everything to
visible.
This doesn’t work with folders because some of them should be hidden by
default (the ones not at the current level).
We can account for this special case (empty search term) by removing
the `display` CSS attribute when the search term is empty. This means
that each item’s visibility will be controlled by whatever is set in the
CSS file. Using jQuery Setting a property to `''` removes it.
Not everyone knows how to use `ctrl` + `f`, and it’s not scoped to
just the list of templates.
The template you want to work with is often not the first one in the
list, but ordering by created at is useful for other reasons (mainly
around first time use).
This commit adds a find as you type control which aims to give users a
quick way of getting to the template they want to work with.
