Hallo,
gut, das können wir machen.
Wenn Du so codierst,
und Du diese Zeilen im script siehst,
, // First-level sub-question codes
// Second-level sub-question codes
wird Dir schnell klar, wie es funktioniert.
Dazu fügst Du folgendes javascript und auch das css Stückchen in den Fragetext ein (im Quellcode-Modus) (immer vorausgesetzt, Du hast die Rechte dazu)
Code:
<script type="text/javascript" charset="utf-8">
// A function to handle "child" checkboxes
function dependantCheckboxes(qID, primaryCodes, secondaryCodes) {
// Identify the elements annd assign classes/attributes
var thisQuestion = $('#question'+qID);
thisQuestion.addClass('with-dependants');
$.each(primaryCodes, function(i, val) {
var thisItem = $('li[id$="X'+qID+val+'"]');
$(thisItem).addClass('level-1 parent-item').attr('data-code', val).attr('data-level', '1');
});
$.each(secondaryCodes, function(i, val) {
var thisItem = $('li[id$="X'+qID+val+'"]');
var thisParent1 = $(thisItem).prevAll('li[data-level="1"]:eq(0)');
$(thisItem).addClass('level-2 parent-item child-item').attr('data-code', val).attr('data-level', '2').attr('data-parent-1', $(thisParent1).attr('data-code'));
});
// A function to handle the states of child items
function handleChildren(el) {
var thisitem = $(el).closest('li');
var thisCode = $(thisitem).attr('data-code');
var thisLevel = $(thisitem).attr('data-level');
var thisChildren = $('li[data-level="'+(Number(thisLevel)+1)+'"][data-parent-'+thisLevel+'="'+thisCode+'"]', thisQuestion);
// Hide/show the secondary answers accordingly
if (!$(el).is(':checked')) {
$(thisChildren).fadeOut(300, function(e) {
$('input:checkbox', thisChildren).prop('checked', false).trigger('change');
});
}
else {
$(thisChildren).fadeIn(300);
}
}
// Initial states of the secondary answers
$('.parent-item input:checkbox', thisQuestion).each(function(i) {
handleChildren($(this));
});
// A listener on the primary answer to show or hide secondary answers
$('.parent-item input:checkbox', thisQuestion).on('change', function(e) {
handleChildren($(this));
});
}
$(document).on('ready pjax:scriptcomplete',function(){
dependantCheckboxes(
{QID},
['SQ1', 'SQ2', 'SQ3'], // First-level sub-question codes
['SQ31','SQ32','SQ33', 'SQ34'] // Second-level sub-question codes
);
});
</script>
Code:
<style type="text/css">.with-dependants .child-item {
display: none;
}
.with-dependants li.level-2 {
margin-left: 2.5em;
}
.with-dependants li.level-3 {
margin-left: 5em;
}
</style>
Viel Erfolg

PS.
Kurze Frage am Schluss:
Woher kommen denn diese ganzen "Style Definitions"?
