You can loop through a structure to output its contents, as the following example shows:

<!--- Create a structure and set its contents. --->
<cfset departments=structnew()>

<cfset val=StructInsert(departments, "John", "Sales")>
<cfset val=StructInsert(departments, "Tom", "Finance")>
<cfset val=StructInsert(departments, "Mike", "Education")>

<!--- Build a table to display the contents --->
<cfoutput>
<table cellpadding="2" cellspacing="2">
    <tr>
        <td><b>Employee</b></td>
        <td><b>Department</b></td>
    </tr>
    <!--- Use cfloop to loop through the departments structure. 
    The item attribute specifies a name for the structure key. --->
    <cfloop collection=#departments# item="person">
        <tr>
            <td>#person#</td>
            <td>#Departments[person]#</td>
        </tr>
    </cfloop>
</table>
</cfoutput>
