NgSurvey has few settings to allow you to customize the behavior of how it works. These settings can be accessed from NgSurvey -> Settings menu item on your administration screen.
Load Bootstrap 5 CSS: Enable this option if your template do not use Bootstrap 5 CSS library or it does not load it automatically. NgSurvey is built on the Bootstrap library and loads the customized version of it. The CSS is namespaced, so it will not interfere with other elements on the page.
Maps Service: Select the maps service you would like to use to show the maps. Google Maps and Openstreetmaps are supported as of now.
