You can do that by registering a new settings plugin. Just add the registerPlugin call before you do your settings.sync()
In the plugin, map the name/value pairs to an array using jQuery, then add the current value to the array.
settings.registerPlugin({
types: ['mySelect'], // This is your data-type for the <select>
set: function (element, value, trim) {
// Here we set the options based on the name/value pairs that were saved previously.
element = $(element);
if (value) value.forEach(function (mapping) {
if (mapping.name === 'value') {
element.val(mapping.value);
}else{
element.append('<option value="'+mapping.value+'">'+mapping.name+'</option>');
}
});
//////////////////
// Here you probably want to append any default options if they don't already exist.
//////////////////
},
get: function (element, trim, empty) {
// Here we get the mapping for saving into the database.
element = $(element);
var value = [];
element.children().each(function (i, option) {
option = $(option);
value.push({name:option.text(),value:option.attr('value')}); // Get the text and value of each <option>
});
value.push({name:'value',value:element.val()}); // Get the current value.
// return the mapping.
return value;
}
});
In the template, you would just do this:
<select data-type="mySelect" data-key="something"></select>
