Brainstorm IT

This plugin can be used to list locations. It adds a custom post type for locations, which can be manipulated via the admin panel. The locations can be displayed on a map and in a table. In addition, a search field can be added that allows users to search for relevant locations.
The functionality is added to a page or post via shortcodes:
<ul>
<li>[smooth-location-map]</li>
<li>[smooth-location-search]</li>
<li>[smooth-location-table]</li>
</ul>
The settings can be configured by passing attributes to the shortcodes, like so:
[smooth-location-map width=”500px” height=”300px” …more attributes]
None of the attributes are required. The following attributes are available:
<ul>
<li>width: defaults to “500px”</li>
<li>height: defaults to “300px”</li>
<li>center: defaults to “37.752530,-122.447777”</li>
<li>geolocation: defaults to “false”</li>
<li>maptype: defaults to “HYBRID”</li>
<li>zoom: defaults to 7</li>
<li>icon_url: url for different icon image</li>
<li>shadow_url: url for shadow of different icon image</li>
</ul>
The same functionality is available via do_action() calls with the same name as the shortcode.
In addition, the following filters are available to modify the HTML output, if necessary:
<ul>
<li>smooth_location_map_filter</li>
<li>smooth_location_search_filter</li>
<li>smooth_location_table_filter</li>
</ul>

This plugin creates two taxonomies for categorizing pages, and their respective archives.
Upon activation, two pages are created that serve as the top-level archives. They are initially named ‘Categories’ and ‘Areas Served’, but may be updated to suit your needs. These pages will display a visual category selection that link to paginated listings of all the content pages associated with each taxonomy.
Pages can be easily assigned to the custom taxonomies by using the checkbox options added to the Edit Page admin area.
<h4>Custom Categories</h4>
This taxonomy is intended for products or services, for example: “Bathrooms,” “Kitchens,” “Outdoor,” etc. All categories in this taxonomy will exist as top-level items (no parent/child relationships).
<h4>Areas Served</h4>
This taxonomy is intended to use US cities and states in parent/child relationships, for example: Texas > Dallas. Properly setting up these locations will allow the Areas Served archive page to create separate state pages with a sub-listing of all its cities.
