Here is a possible solution (if I understand you correctly).
1:
Add a list named “LookupList_SPJSLookupOneToMany” with two columns “Level1” and “Level2”, and fill it like the attachment shows.
2:
Add four field to your main list: “SPJSLookupParent”, “SPJSLookupChild1”, “SPJSLookupChild2” and “SPJSLookupChild1”.
3:
Add this to the Custom JS:
spjs.lookup.init({
"fieldToConvertToDropdown":["SPJSLookupParent"],
"listName":"LookupList_SPJSLookupOneToMany",
"listBaseUrl":"/DFFS",
"optTextFieldInternalName":"Level1",
"sortFieldName":"Level1",
"filterObj":{
"on":false,
"folder":"", // Leave empty to search in all folders
"CAML":null, // If used, the rest of the filterObj settings are disregarded
"fin":"Completed",
"isLookup":false,
"operator":"Neq",
"filterVal":"1"
},
"dropDownDefaultvalue":"...",
"addYouOwnValue":{
"on":false,
"linkText":"Write your own value"
},
"addToExternalList":{
"on":false,
"customFunction":null, // Function name as a string. If a function name is supplied, this will be used in stead of the default function. The function will be passed the argument object as a parameter.
"linkText":"Add new item",
"saveNewItemText":"Save new item"
},
"debug":false
});
$("#SPJSLookupParent_spjs_lookup").change(function(){
var val = $(this).find("option:selected").text();
// Delete current instances of child selects
spjs.lookup.kill("SPJSLookupChild1");
spjs.lookup.kill("SPJSLookupChild2");
spjs.lookup.kill("SPJSLookupChild3");
// Add new
spjs.lookup.init({
"fieldToConvertToDropdown":["SPJSLookupChild1","SPJSLookupChild2","SPJSLookupChild3"],
"listName":"LookupList_SPJSLookupOneToMany",
"listBaseUrl":"/DFFS",
"optTextFieldInternalName":"Level2",
"sortFieldName":"Level2",
"filterObj":{
"on":true,
"folder":"", // Leave empty to search in all folders
"CAML":null, // If used, the rest of the filterObj settings are disregarded
"fin":"Level1",
"isLookup":false,
"operator":"Eq",
"filterVal":val
},
"dropDownDefaultvalue":"...",
"addYouOwnValue":{
"on":false,
"linkText":"Write your own value"
},
"addToExternalList":{
"on":false,
"customFunction":null, // Function name as a string. If a function name is supplied, this will be used in stead of the default function. The function will be passed the argument object as a parameter.
"linkText":"Add new item",
"saveNewItemText":"Save new item"
},
"debug":false
});
});
If you change the name of any of the fields, adapt the code by changing the names.
Hope this helps,
