-# Skeleton -- a Kanboard plugin template
+# ShrinkVertically -- keep the board horizontal scrollbar visible
 
-A minimal, working Kanboard plugin that you copy and rename as the starting point for a
-real plugin. By itself it does only one trivial thing: it renders the word "Skeleton" at
-the top of every page. It changes no data and runs no database migration.
+A tiny Kanboard plugin that fixes the vertically-collapsed board view so the bottom
+horizontal scrollbar stays on screen.
 
-## What it demonstrates
+## The problem
 
-- A complete `Plugin.php` registration class with all the metadata Kanboard shows in
-  Settings -> Plugins (name, description, author, version, homepage, compatible version).
-- A template hook (`template:layout:top`) that injects a template into the page.
-- Asset hooks (`template:layout:css` and `template:layout:js`) that load a stylesheet and
-  a script. They are empty for now but prove the injection path works -- handy when a real
-  plugin needs custom CSS or JS.
-- The standard plugin directory layout, with stub folders (`Controller/`, `Model/`,
-  `Schema/`, `Locale/`, `Test/`) ready to grow into.
+Kanboard's board gear menu has an "expand vertically / collapse vertically" toggle. When
+collapsed, each column gets a limited height so the horizontal scrollbar sits closer.
+Core implements this with a single rule:
+
+```css
+.board-task-list-compact { max-height: 90vh; }
+```
+
+That `90vh` is measured from the top of the viewport and does not account for the page
+header above the board. So even when collapsed, the column plus the header together
+exceed the viewport height and the horizontal scrollbar is pushed below the fold.
+
+## The fix
+
+This plugin injects one CSS rule (via the `template:layout:css` hook) that replaces the
+proportional `90vh` with a fixed-pixel budget for the chrome above and below the task
+list:
+
+```css
+#board td .board-task-list.board-task-list-compact {
+    max-height: calc(100vh - 120px) !important;
+}
+```
+
+The `120px` reserves room for the page header, the board column header, the horizontal
+scrollbar, and a little breathing space. A fixed-pixel budget is more reliable than a
+proportional value because that chrome is a fixed height regardless of screen size.
+
+It changes nothing else: no data, no JavaScript, no database migration. The override only
+applies while columns are collapsed (when core adds the `board-task-list-compact` class).

 ## Installation
 
-No build step and no dependencies.
+Copy this folder into your Kanboard installation as `plugins/ShrinkVertically/`. The
+directory name must be exactly `ShrinkVertically` (Kanboard derives the plugin namespace
+from the folder name). Reload the board; no build step, no configuration.
 
-1. Copy this folder into your Kanboard installation as `plugins/Skeleton/`.
-2. Reload any page. The word "Skeleton" appears at the top.
-3. Confirm it under Settings -> Plugins.
+## Tuning
 
-To uninstall, delete `plugins/Skeleton/`. Nothing else is left behind.

-## How to fork this into a new plugin
-
-1. Copy the folder and rename it, e.g. `plugins/MyPlugin/`. The folder name must match the
-   namespace and start with a capital letter.
-2. In `Plugin.php`, change the namespace from `Kanboard\Plugin\Skeleton` to
-   `Kanboard\Plugin\MyPlugin`.
-3. Update the metadata methods (`getPluginName`, `getPluginDescription`, `getPluginAuthor`,
-   `getPluginVersion`, `getPluginHomepage`, `getCompatibleVersion`).
-4. Update the hook target paths: the lowercase prefix in `'skeleton:layout/header'` and the
-   `plugins/Skeleton/Asset/...` asset paths must match the new plugin name.
-5. Replace `Template/layout/header.php` with your real template, or attach to a different
-   hook. See the Kanboard plugin hooks documentation for the full list of hook points.
+Edit the single `120px` value in `Asset/css/shrink-vertically.css`. Increase it if the
+scrollbar is still clipped (for example with a taller theme header); decrease it to make
+the collapsed columns taller.
