Filter control

Use

Add a toggle control that allows viewers to filter by field values or custom selectors.

Example

Filter by field:

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

Filter using custom selectors:

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

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

Supported properties

  • target a selector that controls which items the filter applies to. Defaults to *, which will apply the filter to all items.
  • 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
    • true allows multiple values to be showcased
    • false allows only a single value to be showcased at a time
  • 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 filter control.

Supported children

If you don't supply a field to filter 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

Filter elements by one or more skills using a dropdown:

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

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

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

Filter connections by toggling between two types (with personal selected by default):

@controls {
  top {
    filter {
      target: connection;
      as: label;
      multiple: false;

      option {
        label: "Personal";
        selector: personal;
        default: true;
      }

      option {
        label: "Business";
        selector: business;
      }
    }
  }
}

Filter elements by type but select all types by default:

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