jQuery Grid Plugin - jqGrid

Hi,

I'm trying to get a custom search working and using a web service to populate one drop down lists of the search criteria

The documentation says to use the surl parameter and edittype:'select', which I am doing. 

{ label: 'Type', name: 'type', stype: 'select', surl: '../../../Services/Leads/GetLeads.svc/GetLeadTypeSelect' },

The web service is then called and the html returned, but the problem is that as it is returned as a json string, the string is encoded and doesn't generate a dropdown list in the code. 

My web service returns (as a string)...

<select><option id='1'> value 1 </option></select>

but this is transformed into

"<select><option id='1'> value 1 <\\/option><\\/select>"

(note the escape characters)

When inserted into the page, this obviously will not display a correctly formed dropdown list

Any help please on how I form my web service to return the expected html in the correct form

Thanks in advance,

Colin.
