This plugin allows WordPress to load data from a number of neighborhood-related APIs to be presented on a single page or within your own pages / posts
Yes. All of the styles are controlled via an external CSS stylesheet named client.css (located in the 'css' folder). You can easily override any of the styles in there. Be aware, however, that the default styles were created to be compliant with all of the branding requirements of the different APIs. It's possible that overriding any of the styles could put you out of compliance with the API provider(s).
There are a number of pre-built images you can use to use as calls to action on your sidebar or anywhere else. The images are available in the following colors: black, blue, green, orange, and red. The images can be found in the following folder: /wp-content/plugins/local-market-explorer/images/badges
From your WordPress admin interface, simply navigate to Appearance -> Widgets, then you can drag + drop the "Local Market Explorer Areas" from the "Available Widgets" to a sidebar on the right (such as "Sidebar 1"). Once the widget is placed, you can click the down-arrow on the newly placed widget to customize the title.
The module is driven by a private API call that needs permissions to be granted to a specific Zillow API key. To request access to this API, simply fill out the API upgrade form located here and select "Local Market Explorer WordPress Plugin" in the API request type field. Once the request is processed, your market activity module should populate automatically with recent sales data.
