Can anyone help me here?

my code below shows a list of branch locations

Code:
<fieldset>
        <label>Branch Name <span class="error-text">*</span></label>
        <select name="branchname" id="branchname">
			<#loop:rootsection#>
                <#if:rootsection.sectionid:eq:2#>
                  	
                    	<#loop:rootsection.subsections#>
                           <option>{rootsection.subsections.title}</option>
                        <#/loop#> 
            	
                <#/if#>
			<#/loop#>  
		</select>
	</fieldset>
I would like to show all branches within each branch location

Like this:

East Sussex
branch 1
branch 2
West Sussex
branch 3
branch 4
