The category button bar is a new category selection interface available to WordPress Premier and MySLP Enterprise subscribers. This new feature is enabled under the Store Locator Plus (WPSLP) or Advanced Options menu then select Settings | Search | Appearance | Category Selector.
The button bar will show clickable links that display the icon and category name for the category which will filter locations that match. The styling for the display will vary based on which plugin style you select. Currently the Bennett style from our Plugin Style Gallery is configured to appear as a button bar. Other styles make show checkboxes or other styles depending on how the CSS is designed.
Functionality is based on a single-category selection. Clicking a new category will turn off all other categories.
The map center, either the Center Map for initial map loading or the address a user entered, is retained as is the initial or current radius. The map will zoom in-and-out to show all locations that match within the radius of the center point.
Here is the button bar using the Bennet plugins style on a modified version of the Exists theme that is deployed on the Bennet Trim Tabs site. This video is on our development servers.
