Store and Category Manager interface is available if you have the  Power  Add-on installed (for WPSLP users) or have the MYSLP Professional level or higher. You will see a tab “Categories” in your Store Locator Plus User Interface.

Under side menu MYSLP/StoreLocatorPlus menu

Once you open the Category Tab  you can begin to add categories and slugs or edit existing.  Set Markers and Icons per category (optional) if you want those to appear in place of map markers.  A Bulk action drop down to delete some or all categories is  at the top of the category box.

Settings/Search

You can choose to show the categories that you have created in a drop down menu as part of the search form.  There are additional category selector options available for WPSLP premier subscribers  or MYSLP Enterprise subscribers (example see Checkbox selector). You can add text as a label that will display  at the top of the categories drop down menu, or you can leave blank.  You can also add text for the category select box that will appear in front of the category drop down on the user interface.

Search using Category

Turn on a simple drop down menu or cascading parent category menu with automatically displayed/hidden child menus for users to filter location results by assigned categories. If you have WPSLP Premier subscription, or MYSLP Enterprise there are additional options on hierarchy rules such as Parent/child drop down menus on the same search form .
Note: A Premier feature requires an active Premier subscription, see the  Tutorial for this feature. Please Note this tutorial is outdated, so with newer versions you will not see the words tagalong, Enhanced Search etc in your plug-in. The premise explaining the parent child relationship is the same.
