You can introduce variable which will be visible inside loop (In official documentation: Setting contextual template parameters, accessible in all nested contexts as ~nameOfParameter)

<select id="Test" TestAttr="{{:LocationId}}">  
    {{for #parent.parent.data.Location ~locationId=LocationId}}
       <option value="{{:~locationId}}"...

EDITED POSTSCRIPT:

The above link is to previous documentation, now superceded.

For current documentation, see Accessing parent data.
