RequestUriForOverlayViewHelper
==============================

This ViewHelper creates an URI with a special parameter which allows the map to
be visible for the user.

Examples
========

..  _viewhelper-request-uri-for-overlay-basic-example:

Basic example
-------------

..  code-block:: html

    <a href="{m:requestUriForOverlay()}">
      Link to current page. Map will be shown somewhere on that page.
    </a>

..  _viewhelper-request-uri-for-overlay-scroll-to-content:

Scroll to content element
-------------------------

If you add `ttContentUid` to ViewHelper it will add a link section (#174)
to the end of the URI. If all of your content elements contain an `id` attribute
like `c174` the target page will scroll to this specific content element
directly.

..  code-block:: html

    <a href="{m:requestUriForOverlay(ttContentUid: ttContentUid)}">
      Link to current page and scroll to content element with map.
    </a>
