- `<GhInputWithSelect>` acts as a typical text input element but will also show options that are filtered whilst typing. Useful for inputs where there should be suggestions or the ability to choose an existing option
- updated `<GhSearchInput>` to use the renamed and slightly modified trigger
refs https://github.com/TryGhost/Team/issues/973
- we have more uses for an input-based trigger for a power select component so the rename prepares the input-based trigger we use for the site search for more general usage
- removed hardcoded search icon and class, they can be passed in as options via the `@extra` param
no issue
Keeps component JS backing files and template files in the same directory which avoids hunting across directories when working with components. Also lets you see all components when looking at one directory, whereas previously template-only or js-only components may not have been obvious without looking at both directories.
- ran [codemod](https://github.com/ember-codemods/ember-component-template-colocation-migrator/) for app-level components
- manually moved in-repo-addon component templates in `lib/koenig-editor`
- removed all explicit `layout` imports as JS/template associations are now made at build-time removing the need for them
- updated `.embercli` to default to new flat component structure
