Focus control

When do you use it?

The focus control allows you to use focus on a specific field across all elements, meaning that the control will toggle on all elements with that field + their connections. You can indicate whether you want the connections to be "out 1" (only first-degree connections), or "out 2" (first- and second-degree connections), etc.

Here are some great uses of the focus control:

• Focus by the “label” field to quickly zoom in on one element and its neighboring connections

• Focus by a specific field to quickly see which elements on the map have that value in their profile field, and what their immediate connections are

Basic Editor

To create a cluster control, follow these steps:

1. Click the settings icon on the right to open the editor, then click "Add custom control".

2. In the menu that opens up, change the value of the first dropdown to "Focus elements by field".

3. Use the other dropdowns to customize the look and location of your controls

4. Click Save at the bottom to save your changes

5. To add multiple controls, repeat steps 1-4 for each control.

Advanced Editor

If you like to get into the nitty-gritty of the advanced editor, you can type out controls directly. The advanced editor also allows for more advanced controls, as explained below.

Focus by field, basic syntax:

@controls {
  top {
    focus {
      by: "element type";
    }
  }
}

Focus using custom selectors:

@controls {
  top {
    focus {
      option {
        label: "Influential";
        selector: ["tags"*="influential"];
      }

      option {
        label: "Emerging Leader";
        selector: ["tags"*="emerging"];
      }
    }
  }
}

Supported properties

• by is the field you'd like to use for filtering wrapped in double quotes (if you don't include by: field you need to list out each option - see "supported children" guidance below)

• as controls how the control is presented. Do you want a list of labels, buttons, or a dropdown for activating filter?

  • labels show options as a list of clickable labels

  • buttons show options as a group of buttons

  • dropdown show options as dropdown

• multiple controls whether more than one value can be selected at a time

  • false allows the reader to only select a single option

  • true allows the reader to select multiple options

  • match-all allows the reader to select multiple options, and only shows items that match all of the selected options

• placeholder the text to display when nothing is selected (for as: dropdown only)

• summary override the summary that's shown for the current selection (for as: dropdown). The summary will be shown regardless of what's selected so there's no need to use placeholder in this case.

• default defines which field values should be selected by default (for by: "field" only). Use select-all to select everything by default (or show-all for a similar effect without selecting everything by default).

• except allows you to remove field values from the available choices. Wrap the values you want to remove in quotes and separate multiple values by commas.

• only is similar to except but allows you to explicitly define which field values should be included as available choices.

Check out our controls reference to see the full list of properties and values recognized by the focus control.

Supported children

If you don't supply a field to focus by, each option must be listed separately. The available options are defined by option blocks nested within the control. Each option supports the following properties:

• label the text to display for that option

• selector the selector to use for the filter

• default

  • true value is selected by default

  • false value is unselected by default

More examples

Focus elements by one or more skills using a dropdown:

@controls {
  top {
    focus {
      target: element;
      by: "Skills";
      as: dropdown;
      multiple: true;
      placeholder: "Select one or more skills"
    }
  }
}

Focus by location, but only for items that have a location:

@controls {
  top {
    focus {
      by: "Location";
      target: ["Location"];
    }
  }
}

Focus elements by type, but select all types by default:

@controls {
  top {
    focus {
      target: element;
      by: "Element type";
      default: select-all;
    }
  }
}
