# _PolicyLayout

Full BOL layout for policy pages: page header, top menu, side menu, policy header bar, and the context form. Consumers select it as the `Layout` of pages derived from `BolPolicyModel`.

## Purpose
- Compose the BOL chrome with the policy header and the context textbox, which is rendered as a text input when `ChangeContextPrivilege` is set and as a hidden input otherwise (presentation only, not server-side authorization) ([BR-BOLMIDDLEWARE-019](../../business-rules.md#br-bolmiddleware-019-context-textbox-visibility)).
- Show the error view when the menu is missing ([BR-BOLMIDDLEWARE-016](../../business-rules.md#br-bolmiddleware-016-null-menu-error-view)).

## Context
- Namespace: `BolMiddleware.Pages.Shared`
- Assembly/package: `BolMiddleware`

## Public members
| Member | Signature | Purpose |
| --- | --- | --- |
| Layout view | `Pages/Shared/_PolicyLayout.cshtml` | Razor layout bound to `BolPolicyModel` that renders the header, menus, policy header, context form `frmWebContext`, and the page body. |
| Optional partials | `MiddlewareIncludes/siteStyles`, `siteHeaderScripts`, `siteBodyPartial`, `siteHeaderBarPartial` | Consumer-supplied partials the layout includes when present; they are not part of this library. |

## Behavioral notes
- Loads the font stylesheet from a CDN and Bootstrap 5.3.2 with a subresource integrity hash, plus `_content/BolMiddleware` assets.

## Constraints and usage notes
- The page model must derive from `BolPolicyModel`.
