Suggestions don't appear in dropdown, when loading from remote source

[Saeven]

I configured a field like so:

$('#industry_include').selectize({
        delimiter: ',',
        valueField: 'value',
        labelField: 'name',
        options: [],
        persist: false,
        create: false,
        load: function(query, callback) {
            if (!query.length) return callback();
            $.ajax({
                url: '/sales/industry/search/' + query,
                error: function() {
                    callback();
                },
                success: function(res) {
                    callback(res);
                }
            });
        }
    });

However, though the query succeeds, no dropdown appears. If I mouse out, and then back in, the dropdown appears with the proper search results in it.

When the original search occurs, line 2110 in the standalone build,

self.hasOptions = results.items.length > 0 || has_create_option;

Returns that results.items.length is zero, though results were clearly returned.

Can you give an excerpt of your data?

[DaveRev]

I also have this issue, this is my code:

$('.select-repo').selectize({
valueField: 'code.value',
labelField: 'code.value',
searchField: 'code.value',
options: [],
create: false,
render: {
    option: function(item, escape) {
        // return  item;
        return '<div>' +
            '<span class="title">' +
                '<span class="name"><i class="icon ' + (item.code.value ? 'fork' : 'source') + '"></i>' + item + '</span>' +
                '<span class="by">' + item.code.value + '</span>' +
            '</span>' +
            '<span class="description">' + item.description.value + '</span>' +
            '<ul class="meta">' +
                (item.price.value ? '<li class="language">' + item.price.value + '</li>' : '') +
                '<li class="watchers"><span>' + item.code.value + '</span> watchers</li>' +
                '<li class="forks"><span>' + item.price.value + '</span> forks</li>' +
            '</ul>' +
        '</div>';
    }
},
// score: function(search) {
//     var score = this.getScoreFunction(search);
//     return function(item) {
//         return score(item) * (1 + Math.min(item.watchers / 100, 1));
//     };
// },
load: function(query, callback) {
    if (!query.length) return callback();
    // console.log(query);
    $.ajax({
        url: 'http://sonnenkraft/symphony/api/entries/ricambi/?auth-token=4b656dca&format=json&fields=code&filter[code]=regexp:' + encodeURIComponent(query),
        // url: 'https://api.github.com/legacy/repos/search/' + encodeURIComponent(query),
        type: 'GET',
        dataType: 'json',
        error: function() {
            callback();
        },
        success: function(res) {
            var theJson={};
            theJson=res;
            // callback(res.entry);
            // console.log(theJson);
            callback(theJson.response.entry.slice(0,4));
        }
    });
}

});

end these are the data that I retrieve via ajax:

{"response":{"section":{"_id":"21","_handle":"ricambi","value":"Ricambi"},"entry":[{"_id":"34433","_immagini":"1","_articoli":"0","code":{"_handle":"ft-111144","value":"FT-111144"}},{"_id":"34366","_immagini":"1","_articoli":"0","code":{"_handle":"941111","value":"941111"}},{"_id":"34365","_immagini":"1","_articoli":"0","code":{"_handle":"941110","value":"941110"}},{"_id":"34285","_immagini":"1","_articoli":"0","code":{"_handle":"850111","value":"850111"}},{"_id":"34252","_immagini":"1","_articoli":"0","code":{"_handle":"811115","value":"811115"}},{"_id":"34251","_immagini":"1","_articoli":"0","code":{"_handle":"811114","value":"811114"}},{"_id":"34250","_immagini":"1","_articoli":"0","code":{"_handle":"811113","value":"811113"}},{"_id":"34249","_immagini":"1","_articoli":"0","code":{"_handle":"811110","value":"811110"}},{"_id":"34248","_immagini":"1","_articoli":"0","code":{"_handle":"811108","value":"811108"}},{"_id":"34247","_immagini":"1","_articoli":"0","code":{"_handle":"811106","value":"811106"}},{"_id":"34246","_immagini":"1","_articoli":"0","code":{"_handle":"811105","value":"811105"}},{"_id":"34245","_immagini":"1","_articoli":"0","code":{"_handle":"811104","value":"811104"}},{"_id":"34184","_immagini":"1","_articoli":"0","code":{"_handle":"211107","value":"211107"}},{"_id":"34183","_immagini":"1","_articoli":"0","code":{"_handle":"211106","value":"211106"}},{"_id":"34182","_immagini":"1","_articoli":"0","code":{"_handle":"211105","value":"211105"}},{"_id":"34181","_immagini":"1","_articoli":"0","code":{"_handle":"211104","value":"211104"}},{"_id":"34180","_immagini":"1","_articoli":"0","code":{"_handle":"211103","value":"211103"}},{"_id":"34179","_immagini":"1","_articoli":"0","code":{"_handle":"211102","value":"211102"}},{"_id":"34178","_immagini":"1","_articoli":"0","code":{"_handle":"211101","value":"211101"}},{"_id":"34059","_immagini":"1","_articoli":"0","code":{"_handle":"182111","value":"182111"}}]}}

@DaveRev In your case, selectize doesn't support accessing nested values with dot notation. You'll have to do something along the lines of this in your load callback:

callback(theJson.response.entry.slice(0,4).map(function(item) {
    return {
        _id: item._id,
        _immagini: item._immagini,
        _articoli: item._articoli,
        _handle: item.code._handle,
        value: item.code.value
    };
});

[DaveRev]

Thanks for the quick reply, it works, but I'm getting an issue when I select an item. The select tag don't get the value of the item that I choose, also changing the option of selectize like this:

valueField: 'value',
labelField: 'value',
searchField: 'value',

So when I submit the form, select hasn't got value. How can I solve this?

[DaveRev]

Sorry, I found the issue, there was another instance of selectize working on the same select tag.

[patie]

@Saeven same problem here, same code

[donmccurdy]

Same issue, but here's a simplified example (no API required) —

$input.selectize({
    options: [],
    create: false,
    delimiter: ',',
    valueField: 'key',
    labelField: 'value',
    load: function (query, callback) {
        callback([
            {key: 1, value: 'One'},
            {key: 2, value: 'Two'},
            {key: 3, value: 'Three'},
            {key: 4, value: 'Four'},
            {key: 5, value: 'Five'},
        ]);
    }
});

To reproduce:

1. Type something ("one" for example") into the input.
2. No results appear
3. Click out of / blur the input.
4. Click back into the input.
5. Results now appear.

Using v0.12.0

[donmccurdy]

Oh, shoot ok I found my problem (which might be the same as the OP). I just needed to specify a searchField option. Adding that fixes the example above.

[mtangoo]

@donmccurdy That is it. Thank you!

[JohnDotOwl]

Facing the same issue, replaced a new API but 100% the same format. The dropdown just wont bloody appear until i click outside and back into the dropdownlist again

[mtangoo]

Have you specified searchField?

[v2lrf]

✅ Work Well

for Ajax (remote data) , Json , Rails, item dropdown , Selectize Vs Select2 ?

Finally, job done and work fine with Select2 🤷🏽‍♂️
initial posthere

if need the access repo tell me bye

As others have alluded to the issues lies with a poorly configured searchField parameter.

refreshOptions runs

var query             = $.trim(self.$control_input.val());
var results           = self.search(query);

So what happens is AJAX returns 10 results, self.search uses searchField and further filters the AJAX results. If searchField is misconfigured then nothing gets displayed. If you click out and refocus then it displays the AJAX results because no filtering took place.

Personally I wouldn't expect this extra filtering step; I'd just expect it to display the AJAX results.

[paperscissors]

100% on the poorly configured searchField parameter. This took me a long time to figure out, because for my case I've got a search endpoint that searches by an internal product code, but then displays the product name in it's stead.

So, in effect, since the internal product code doesn't exist in the returned name text, it doesn't show anything because selectize is filtering again by the search param.

I ended up including the internal product code in the final text display and that served as a good workaround (product name (internal product code)). It seems like maybe a redundant level of filtering, as mentioned above...
