# `PhoenixKitProjects.Web.ProjectShowLive`
[🔗](https://github.com/BeamLabEU/phoenix_kit_projects/blob/v0.18.0/lib/phoenix_kit_projects/web/project_show_live.ex#L1)

Show a project with a vertical timeline of assignments.
Supports inline status changes, duration editing, dependency
management, and tracks who completed each task.

## List / Timeline / Calendar tabs

The page has three views — the vertical task list, the embedded
`ProjectGanttLive` Timeline, and the embedded `ProjectCalendarLive` month
calendar — toggled by tabs under the shared header. Switching is instant (an
assign flip) and each nested LV is lazily mounted on first open, then kept
(so the gantt's zoom/expand and the calendar's month navigation survive
switching back). **The tabs render in every mount context, embedded
`live_render` renders included** (only templates stay list-only). Note this
means the Timeline/Calendar tabs are nested `live_render`s, which are
themselves nested LVs when the show page is embedded — deliberate,
server-rendered, so both views show even before any JS loads.

Keeping the URL in sync (the trailing `/gantt` / `/calendar` segment) is
**optional and off by default**: it's only on when `@tab_url_sync?` is true,
which the router-mounted standalone admin page sets (so its deep-linking
keeps working) and an embed can opt into via `session["tab_url_sync"]`. When
on, the `ProjectTabsUrl` JS hook REPLACES the current URL on each switch —
deep links / copy / reload land on the right tab, while back/forward return
to the previous page. Deliberately no per-tab history entries: they'd need
this LV to export `handle_params/3` (which would block `live_render`
embedding), and LiveView's popstate handler treats foreign pushState entries
as live navigation — remounting and crashing on the missing callback. With
sync off the tabs still switch fully — they just never touch the host page's
URL (the right default for an embed, which must not rewrite the host's
address bar).
