Other observations:
-
The issue 177 asked for an opt-in toolbar above the grid, explicitly worrying that changing the default could be unwelcome. This PR takes a different route, an overlay pinned to the grid, always on, no new API. I think that's a reasonable call (no new API surface, and the grid still looks like a plain grid), but since it isn't what was proposed, it would be good to say so on the issue so the reporter knows the toolbar idea was considered and declined.
-
Aura problems: In Aura, if the last column is sortable, it's header can't be clicked to sort it: the new toggle overlays that area and takes the click.

Changing away from ⋮ matches what the issue asked for a bare ⋮ reads as "more actions" and doesn't hint that columns can be hidden. But I don't think CARET_DOWN is the right replacement:
- A caret is a dropdown affordance, conventionally attached to a labelled control. On its own it conveys less than ⋮ did, not more: it says neither "menu" nor "columns".
- More importantly, the toggle now sits in the header row, where the grid's own sort indicator is also a caret/arrow. A lone ▾ in the top-right corner of the header is easy to read as a sorting control.
Also and more important: there is no API to override the icon, so every existing user gets the new appearance on upgrade with no way back. Not an API break, and the minor bump to 2.2.0 is right, but it should be called out in the release notes. And the possibility to override it should be considered as a future enhancement.

@paodb Addressed all but the Aura problems. I also notice some styling issues with Lumo that were not evident when using the caret icon (expect more commits). |
The overload became unused when isMenuToggleColumn stopped resolving the helper of the grid. See #177
Track the height of the first visible header row in the --_fc-grid-helper--header-row-height custom property, and size the toggle to that height, so that the toggle no longer overlaps the second header row. The button is stripped of its padding, border and state overlay in order to occupy exactly the size of the icon, which is configurable through --fc-grid-helper-toggle--button-size. See #177
The toggle floats over the last column, so reserve the width of the toggle in the cells of that column, and paint the toggle over an opaque background, which is configurable through --fc-grid-helper-toggle--background. See #177

Resolve the reported Stylelint errors.
Stylelint reports errors at Line 1, Line 47, and Line 60. Add the required blank lines before the declarations. If the /*- license delimiter is required, add a narrow Stylelint exception for that header instead of changing the license format. These errors prevent a clean Stylelint run.

License delimiter is required.
There was a problem hiding this comment.
@javier-godoy, understood. Keep the required /*- license delimiter unchanged.
The Line 1 Stylelint error requires a narrowly scoped Stylelint exception for this header. The reported declaration-spacing errors at Line 47 and Line 60 remain separate from the license format.

Learning: In `src/main/resources/META-INF/frontend/fcGridHelper/styles.css`, the `/*-` delimiter is required by the license header. Do not change this delimiter to satisfy Stylelint; use a narrowly scoped Stylelint exception when needed.
