Problem: I have set my map initial zoom level to center and zoom in to show all the markers, but when I display the map the initial zoom level is zoomed out showing the entire global map.
Solution: In this case the map is not displayed when the page is loaded, so the initial zoom level calculations are inaccurate. You must trigger a map reload function when the map is displayed to calculate the initial zoom level correctly. The correct function to call is:
WPViews.view_addon_maps.reload_map("map-id");
Place that code after the code used to turn on the map display, and replace map-id with the ID of your map.
Problem: I would like to create a one-to-many relationship between Users and a post type.
Solution: You can either create a proxy post type for Users and relate that proxy post type using Toolset's Post Relationships feature, or you can create a custom usermeta field that stores a reference to the related post by ID.
