What are Maps?

A maps view is used to display records from your database on a map in your Live App. 

Knack uses HERE Maps to display maps and geocode Address field values. You can also use Google as your provider by adding your own API key. This setting can be found on the App Settings > Map Provider page. To learn more about using HERE maps, Google maps, and the differences between them, see our article App Settings: Map Provider.

  • The map view is currently only available on the Pro plan and above.
  • Maps can only display tables that have an Address field. This address field will be geolocated and will determine which records the map will display.
  • When using the latitude/longitude coordinates option for an address field, that location will display as the nearest street address on a map view, rather than the exact coordinates. 
  • Map views will automatically generate direction links that, when clicked, will open a new window for Google Maps where the user can get directions. 
  • Address fields used in Map views where the “Address Autocomplete” functionality is enabled will allow this autocomplete functionality in the search input.

What do maps look like in the Live App?

Maps display multiple records from one of the tables in your database in a graphical HERE map:

On the search results display, a “reset” link will appear. Clicking this will reset all search criteria to easily search again with new criteria.

You can also choose to use Google maps by entering your own API key. See the section above for more details on this. 

Manage Maps

To learn how to add, edit, and delete map views from your app, see About Views. 

Maps Settings

To access the settings of a map view, hover your mouse over the view and click on the pencil icon that appears at the top left of the view.

Source

The source section is used to control the records the map will display. 

  • Filters: the map will display all the table's records by default. Use the data section to add rules to limit which records will be displayed.
  • Sort: control the default sort order of which records will be displayed first.
  • Limit: show all the available records or limit to a specific number.
Currently map views can only show 1000 records at a time.

Map Settings

The Map Settings section is used to control how the map works with your table to display addresses:

  • Address Field: select a field that the map will use as the address to place each location on the map. This field must be the Address type.
  • Note: New maps will use the first address field to display records in the map, as well as the first short text field as a label when displaying address details.
  • Title Field: select a field the map will use to display for an address point. Choose a title, name, or other field that can easily identify the whole record.
  • Map Size: the dimensions of the map in pixels. Use these to control how big you want the map to be.
  • List Width: the width of the list that displays to the right of the map and contains the record details (see below). If the map and list width combined won't fit on the screen, then the list will bump below the map and be the same width as the map.
  • Units: select which unit of measuring distance will be used on the map: Miles or Kilometers.
  • Starting Range: the distance of the range to search by based on the selected unit (above). A record address must be within this distance of the searched address.
  • Starting Point: Blank, Specific Address, or User's Current Location. If Blank, then no records will show until the user initiates a search. If an address is provided then the map will start with records closest to that address. When using the User's Current Location, the browser will ask the user's permission to locate them and use that location.
  • Pin Colors: add custom rules to display different pin colors based on criteria you define.
  • Pagination: pagination determines how many records will show at one time. If the total number of records exceeds the pagination number, then links will be added to the table to navigate all the pages. Options here include:
    • Set how many records to show at a time
    • Let the user set how many records to view per page
    • Show pagination controls at bottom of view
  • Filters: filters give the user tools to further refine which records the map will show. You can add filters as options for the user to add, or as a menu.
    • User Filters: enabling user filters presents options for a user to add any filters they'd like to the map. This will then display an "add filter" link above the map. The map will update as soon as a filter is added. Multiple filters can be added as needed. You can determine if the fields available to filter are limited to the map details or all the table's fields. You can add preset filters that will initially filter the records.
    • Filter Menu: enabling a filter menu will present links above the map the user can click that will filter the records based on the rules you create.

Location List

The List Details section controls the list that displays to the right of the map with additional details about each record:

This follows the same model as the details view.

Design

In the Design section of the view editor, you can customize the title and description of your map or leave them blank. 

Here is what a form looks like with no title or description:
