Locations are added to Store Locator Plus via the SLP menu, locations panel.
NOTE: If you are using the MYSLP SaaS platform you will see a Left side menu under the MySLP for Store Locator Plus. Select “Locations” from the Store Locator Plus sidebar menu or tabs
The best way to Add or edit is via the SLP sidebar menu not the MYSLP sidebar menu. The MYSLP Locations menu for Professional or higher will not show you options for categories for example. To edit click on the edit icon.
