  Manually add an attribute to an overlay
   
• (Step 2)
  Create a single condition in a single filter
   
• (Step 3)
  Create multiple conditions in a single filter
   
• (Step 4)
  Create multiple filters

(Step 1) - Manually add an attribute to an overlay

Perform the procedure in the article at this link: How to manually add an attribute to an overlay

(Step 2) - Create a single condition in a single filter

Definitions

A filter is a set of conditions you configure to block/allow the display of overlays.

A condition is a rule you configure to block/allow the passing of overlays through a filter.

You configure each condition (rule) by considering the overlay attributes.

Add the first attribute row to 3 markers

In this example, a real estate buyer views a map displaying houses for sale. The buyer wants to apply a filter so the map only displays the houses priced between; $100,000 and $200,000.

Create a single condition in a filter

1. At the top of the Layers Panel, click the Filter Icon displaying the tooltip: "Add Filters".
    
2. The "FILTERS" window will appear asking you to select a template. For this example, select: "Blank".
    
3. In the "FILTERS" window, you will see a coloured square (example: blue) above the default condition line.

   In later steps, the square's colour will appear on the left-side of individual overlay rows in the Layers Panel.

   The colour will show which overlays have passed through the filter.

    
4. On the default condition line, click the arrowhead on the right side of the first field. Select the attribute you previously created in the drop-down: "PRICE".
    
5. Click the arrowhead on the right side of the second field. In the drop-down, select: "IS BETWEEN".

   You will see the 5th and 6th fields added to the condition line.

    
6. Click the arrowhead on the right side of the third field. In the drop-down, select: "Value".
    
7. On the fourth field, copy-and-paste the price of "$100,000".
    
8. Click the arrowhead on the right side of the fifth field. In the drop-down, select: "Value".
    
9. On the sixth field, copy-and-paste the price of "$200,000".
    
10. At the bottom of the "FILTERS" window, click the button: "SAVE FILTERS".
     
11. In the Map View, you will see "Marker 1" has been filtered out, because the price, ($99,000), is not between $100,000 and $200,000.

    Only Marker 2 and Marker 3 have passed through the filter.

    Marker 2

    PRICE

    is between

    $100,000

    and

    $200,000

     
    Marker 3

    PRICE

    is between

    $100,000

    and

    $200,000

     

Toggle the condition on/off

1. In the filters section at the top of the Layers Panel, you will see the checkbox condition line: "PRICE is between $100,000 and $200,000"
    
2. To toggle the condition on/off, click the box on the left of the checkbox condition line.

   When the checkbox condition line is toggled on, you will see the coloured rectangle on the left-side of each overlay row that passes through the filter.

    

   On the checkbox condition line, you will see the filter icon is the same colour.

    
3. To prepare for the next steps, toggle the condition off, so the 3 markers are visible.

(Step 3) - Create multiple conditions in a single filter

Add the second attribute row to the 3 markers

Refresh the filters

The Refresh Icon is 2 arrows forming a circle.

Create the second condition in a single filter

1. At the top of the Layers Panel, click the Filter Icon displaying the tooltip: "Add Filters".
    
2. In the "FILTERS" window, you will see the condition you added in the previous example. Under the first condition, click the button: "+ Add Condition".
    
3. At the top of the "FILTERS" window, you will see the single filter’s coloured square now has a drop-down menu. Click the drop-down to select: "Match ANY conditions".
    
4. On the new condition line, click the arrowhead on the right side of the first field. In the drop-down, select the attribute: "PROPERTY TYPE".
    
5. Click the arrowhead on the right side of the second field. In the drop-down select: "IS".
    
6. Click the arrowhead on the right side of the third field. In the drop-down select: "Unique".

   For your reference:

   • Value - Requires you to input a value.
   • Attribute - Enables you to select from all of the "attribute names" added to overlays.
   • Unique - Enables you to select from all of the "attribute values" added to overlays.

    

    
7. Click the arrowhead on the right side of the fourth field. In the drop-down select: "Single Family Residential".
    
8. At the bottom of the "FILTERS" window, click the button: "SAVE FILTERS".
    
9. In the filters section at the top of the Layers Panel, click the checkboxes for this configuration:
   Match ANY - on.
    
    
   • PRICE is between $100,000 and $200,000 - on.
   • PROPERTY TYPE is Single Family Residential - on.

   In the Layers Panel, you will see all 3 markers have passed through the filter.

Require overlays to "match ANY conditions" to pass through a single filter

1. At the top of the Layers Panel, click the Filter Icon displaying the tooltip: "Add Filters".
    
2. At the top of the "FILTERS" window, the single filter’s drop-down menu displays the setting: "Match ANY conditions".

   "Match ANY conditions" means the filter will display the overlays that match any of the multiple conditions.

    
3. In the top-right corner of the "FILTERS" window, click the "X" button.
    
4. Above the 2 checkbox condition lines in the filters section (Layers Panel), you will see the checkbox: "Match ANY".

   If you click to toggle "Match ANY" off, the 2 checkbox conditional lines will be toggled off.

    

   If you toggle "Match ANY" on, you can select whether each checkbox condition line is toggled on/off.

    

   Since "Match ANY" is on, you can toggle one of the condition lines off so:

   The overlays only have to pass through the other condition to be displayed.

    
5. For this example, click the checkboxes to toggle "on" all 3.

   Match ANY - on.

   • PRICE is between $100,000 and $200,000 - on.
   • PROPERTY TYPE is Single Family Residential - on.

    

    
6. In the Map View, you will see all 3 overlays are displayed, because:
    
   Marker 1 matches any condition

   PROPERTY TYPE

   is

   Single-family residential

    
   Marker 2 matches any condition

   PRICE

   is between

   $100,000

   and

   $200,000

    

   PROPERTY TYPE

   is

   Single-family residential

    
   Marker 3 matches any condition

2. At the top of the "FILTERS" window, the single filter’s drop-down menu displays the setting: "Match ANY conditions".
    
3. Click the single filter’s drop-down menu. Then select the setting: "Match ALL conditions".

   "Match ALL conditions" means the filter will only display the overlays that match all of the multiple conditions.

    
4. At the bottom of the "FILTERS" window, click the button: "SAVE FILTERS".
    
5. Above the 2 checkbox condition lines in the filters section (Layers Panel), you will see the checkbox: "Match ALL".
    
6. For this example, click the checkboxes to toggle "on" all 3.

   Match ALL - on.

   • PRICE is between $100,000 and $200,000 - on.
   • PROPERTY TYPE is Single Family Residential - on.

    

    
7. In the Map View, you will see only Marker 2 is displayed, because:
    
   Marker 1 doesn't match all conditions
    
   Marker 2 matches all conditions

   PRICE

   is between

   $100,000

   and

   $200,000

    

   PROPERTY TYPE

   is

   Single-family residential

    
    
   Marker 3 doesn't match all conditions

(Optional) Add a custom label to a filter's checkbox 

1. At the top of the Layers Panel, click the Filter Icon displaying the tooltip: "Add Filters".
    
2. At the top of the "FILTERS" window, the single filter’s drop-down menu displays the setting: "Match ALL conditions".

   Price and Property type - on.

   • PRICE is between $100,000 and $200,000 - on.
   • PROPERTY TYPE is Single Family Residential - on.

(Optional) Hide a filter's condition lines

1. At the top of the Layers Panel, you will see the filter's label. For example: "Price and Property type".
2. To the right of the checkbox's label, click the arrowhead.
3. You will see the filter's label continues to be displayed, and the 2 condition lines are hidden from view.

   Price and Property type - on.

(Step 4) - Create multiple filters

Add the third attribute row to the 3 markers

The Refresh Icon is 2 arrows forming a circle.

Create a second filter

1. At the top of the Layers Panel, click the blue Filter Icon displaying the tooltip: "Add Filters".
    
2. In the "Filters" editor window, you will see the single filter has two condition lines.
    
3. Underneath and to the right of the second condition line, click the button: "+ Add Filter".

   You will see the new filter includes a new:

   • Colored square.
   • Default condition line.

    

    
4. On the default condition line, click the arrowhead on the right side of the first field. In the drop-down, select the attribute: "YEAR BUILT".
    
5. Click the arrowhead on the right side of the second field. In the drop-down select: "IS GREATER THAN".
    
6. Click the arrowhead on the right side of the third field. In the drop-down select: "Value".
    
7. Click the fourth field. Copy and paste the year: "2008".
    
8. At the bottom of the "Filters" editor window, click the button: "Save Filters".

Require overlays to "match ANY conditions" (filter) to pass through multiple filters

1. At the top of the "Filters" editor window, you will see a new drop-down menu located above the first filter’s coloured square.

   The drop-down menu located above applies to every filter (in this example, 2 filters).

    

   So "Match ANY conditions" means the overlays will be displayed:

   If the overlays match the rules of any filter.

    
2. In the top-right corner of the "Filters" editor window, click the "X" button.
    
3. At the top of the Layers Panel, you will see the overall checkbox, "Match ANY" (filter), above the first filter’s overall checkbox: "Match ALL" (conditions).
    
4. For this example, click the checkboxes to toggle “on” all 5:

   "Match ANY" (filter) - on.

    

   Filter 1 - "Match ALL" (conditions) - on.

   • PRICE is between $100,000 and $200,000 - on.
   • PROPERTY TYPE is Single Family Residential - on.

    

   Filter 2

   • YEAR BUILT is greater than 2008 - on.

    

    
5. In the Map View, you will see only Markers 2 and 3 are displayed, because:
    
   Marker 1 doesn't match the conditions of any filter
    
   Marker 2 matches the conditions of any filter
    
    
    
   • Filter 1 - "Match ALL" (conditions)
      
      
      

     PRICE

     is between

     $100,000

     and

     $200,000

      

     PROPERTY TYPE

     is

     Single-family residential

      
   • Filter 2
      
      
      

     YEAR BUILT

     is greater than

     2008

    
    
   Marker 3 matches the conditions of any filter
    
    
    
   • Filter 2
      
      
      

     YEAR BUILT

     is greater than

     2008

      
    
6. In the Layers Panel, you will see the coloured rectangle on the left side of Marker 2's row displays 2 colours.

   The 2 colors mean the overlay passes through 2 filters.

Require overlays to "match ALL conditions" (filters) to pass through multiple filters

1. At the top of the Layers Panel, click the blue Filter Icon displaying the tooltip: "Add Filters".
    
2. At the top of the "Filters" editor window, you will see the drop-down menu located above the first filter’s coloured square.
    
3. Click the drop-down to change the setting to: "Match ALL conditions".

   The drop-down menu located above applies to every filter (in this example, 2 filters).

    

   So "Match ALL conditions" means the overlays will be displayed:

   If the overlays match the rules of all the filters.

    
4. At the bottom of the "Filters" editor window, click the button: "Save Filters".
    
5. In the top-right corner of the "Filters" editor window, click the "X" button.
    
6. At the top of the Layers Panel, you will see the overall checkbox, “Match ALL” (filters), above the first filter’s overall checkbox: "Match ALL" (conditions).
    
7. For this example, click the checkboxes to toggle "on" all 5:

   "Match ALL" (filters) - on.

    

   Filter 1 - "Match ALL" (conditions) - on.

   • PRICE is between $100,000 and $200,000 - on.
   • PROPERTY TYPE is Single Family Residential - on.

    

   Filter 2

   • YEAR BUILT is greater than 2008 - on.

    

    
8. In the Map View, you will see only Marker 2 is displayed, because:
    
   Marker 1 doesn't match the conditions of all filters
    
   Marker 2 matches the conditions of all filters
    
    
    
   • Filter 1 - "Match ALL" (conditions)
      
      
      

     PRICE

     is between

     $100,000

     and

     $200,000

      

     PROPERTY TYPE

     is

     Single-family residential

      
   • Filter 2
      
      
      

     YEAR BUILT

     is greater than

     2008

    
    
   Marker 3 doesn't match the conditions of all filters
