Bootstrap açılır düğmenin html yapısı:
<div class="btn-group">
<button class="btn btn-mini">Action</button>
<button class="btn btn-mini dropdown-toggle" data-toggle="dropdown"><span class="caret"></span></button>
<ul class="dropdown-menu">
<li><a href="#">Action</a></li>
<li><a href="#">Another action</a></li>
<li><a href="#">Something else here</a></li>
<li class="divider"></li>
<li><a href="#">Separated link</a></li>
</ul>
</div>
Önceki yazımda jQuery nesnelerindeki trigger, on olaylarını yüklü jQuery'e iliştirme olayını okuyabilirsiniz:
var obj = $({});
jQuery["on"] = function () {
obj["on"].apply(obj, arguments);
};
jQuery["trigger"] = function () {
obj["trigger"].apply(obj, arguments);
};
Bunu yaptık çünkü Select2 içinde bir event oluşturup her arama sonucunda bir eleman seçtiğinizde tetiklenmesini istiyoruz. Böylece eklenmiş elemanı Select2 dışında kontrol edebilmemizi sağlayacağız.
addSelectedChoice: function (data) {
var enableChoice = !data.locked,
enabledItem = $(
"
" + this.opts.escapeMarkup(formatted) + "
");
choice.find("div").replaceWith("" + formatted + "
");
$.trigger({ type: "cem", val: data, choice: $(choice.find("div")[0])});
}
Tag şeklinde açılacağı ve multiselect hedeflediğim için container içinde menü elemanlarını görüntüleyebilmek için aşağıdaki css içinde bazı değişiklikler yapacağız.
.select2-container-multi .select2-choices {
height: auto !important;
height: 1%;
margin: 0;
padding: 0;
position: relative;
border: 1px solid #aaa;
cursor: text;
overflow: hidden;
background-color: #fff;
background-image: -webkit-gradient(linear, 0% 0%, 0% 100%, color-stop(1%, #eeeeee), color-stop(15%, #ffffff));
background-image: -webkit-linear-gradient(top, #eeeeee 1%, #ffffff 15%);
background-image: -moz-linear-gradient(top, #eeeeee 1%, #ffffff 15%);
background-image: -o-linear-gradient(top, #eeeeee 1%, #ffffff 15%);
background-image: -ms-linear-gradient(top, #eeeeee 1%, #ffffff 15%);
background-image: linear-gradient(top, #eeeeee 1%, #ffffff 15%);
}overflow: hidden ile menü elemanları gizleniyordu. Bunu visible yapacağız ki menü gözüksün.display: inline-block; genişlemeyi otomatik yapabilmemiz için.min-width: 200px; en azından 200px genişliğinde görünsün istiyoruz.Sonuç:
.select2-container-multi .select2-choices {
height: auto !important;
height: 1%;
margin: 0;
padding: 0;
position: relative;
border: 1px solid #aaa;
cursor: text;
overflow: visible;
display: inline-block;
min-width: 200px;
background-color: #fff;
background-image: -webkit-gradient(linear, 0% 0%, 0% 100%, color-stop(1%, #eeeeee), color-stop(15%, #ffffff));
background-image: -webkit-linear-gradient(top, #eeeeee 1%, #ffffff 15%);
background-image: -moz-linear-gradient(top, #eeeeee 1%, #ffffff 15%);
background-image: -o-linear-gradient(top, #eeeeee 1%, #ffffff 15%);
background-image: -ms-linear-gradient(top, #eeeeee 1%, #ffffff 15%);
background-image: linear-gradient(top, #eeeeee 1%, #ffffff 15%);
}Select2'nin css içinde ul içinde li taglarını float:left ile inline-block şeklinde gösteriyor. Bizde dropdown button içinde li kullandığımıza göre ve dikey dizilmiş li menu item dizimiz olsun istediğimiz için
.select2-container-multi .select2-choices li şeklinde tüm li elemanlarını etkileyen stilimizi sadece ilk seviye li elemanlarına uygulamak için şu şekle getiririz: .select2-container-multi .select2-choices > liTüm html kodu:
