Creating a Custom List
You can setup a custom list of cities, counties and/or postal codes and apply it to any of your search pages or Quick Search widgets. If you want to easily refine searches so your leads are only able to search in a target area Custom Lists are a great way to accomplish this goal. To get started making your custom lists, click Design, Settings, and Locations. Then click Create Lists in the upper-right corner.
Step 1: Choose your list type
You can choose from city, county, or postal codes to create the desired list.

Step 2 - Select your locations
This is where you choose which items (city, counties, or postal codes) will display in your custom list. The box on the left display locations you currently have in your custom list. On the right side of the screen are tools for adding locations to your list - you can do these individually or in bulk. You can remove items from the custom list by clicking the checkboxes next to each location's name and then clicking Remove Selected.

Use the Sort drop-down menu to choose a sorting order for your list. Choosing Custom sorting will bring up a pop-up box with a tool you can use to drag-and-drop items in your list to place them in a specific sorting order of your choosing.
When you are done ordering your custom list click Update Order.
To continue, select Finalize and Continue.
Step 3 - Name your custom list
Once your list is looking good it's time to give it a name and save it. If this is a new custom list add the name using the box on the left (examples - "Oregon Cities" or "Coastal Counties") and click Save New List. You can also overwrite a list you already created by using the dropdown menu on the right to select the name of the list you would like to overwrite. Click Overwrite Old List. Note: You can not revert an overwritten list back to its previous state so make sure you want to replace the old list before choosing this option.
Nice job - created and saved a custom location list! One last important step.
Step 4 - Apply your list
To start using your custom list on existing search pages click the button called "Apply to Search Pages".

Pro-Tip: Once you create a custom location list it will show up in your Quick Search widget settings.
