मैं एक ही समस्या का सामना करना पड़ा, मैं इस समस्या को हल करने के लिए jQuery-dropkick-1.0.0 स्क्रिप्ट के लिए कुछ पैचिंग कर दिया। मैंने dropkick ऑब्जेक्ट में एक बल SyncWithSelect विधि जोड़ा।
यहाँ मैं किए गए परिवर्तनों की एक सूची है:
- टैग
- के लिए समर्थन जोड़ने खुला, बंद, forceSyncWithSelect के लिए
- ऐड विधि सीएसएस के लिए चौड़ाई छोड़ने के लिए autoWidth सेटिंग्स जोड़ सकते हैं और isDropkicked
- रखें डिफ़ॉल्ट tabindex 0
- ऑप्टग्रुप तत्व
- f पर डेटा-डीकेग्रुपक्लास विशेषता के साथ ऑप्टग्रुप क्लास विकल्प जोड़ें ix forceSyncWithSelect विधि यदि मान समय के कई दिखाई देते हैं, पहली घटना मेनू चयन पर क्लिक से ही
- टॉगल ले
- (एक कलंक घटना स्क्रॉल पट्टी बातचीत पर शुरू की है स्क्रॉल पट्टी बातचीत पर मेनू को बंद करने से आईई रोकने के लिए, व्यवहार इतना गलत) है
आप उन सभी परिवर्तन नहीं चाहते हो सकता है लेकिन आप एक diff पैच बनाने के लिए और ले आप क्या जरूरत है (यदि आप परिवर्तन लॉग जाने या शीर्ष लेख में इसके बारे में स्रोत जोड़ खुशी होगी, मैं जेमी लॉटरिंग में उन परिवर्तनों का प्रस्ताव देना चाहता हूं, लेकिन मुझे ऐसा करने के लिए गिट हब खाता बनाना होगा।
// Reload the dropkick select widget after options have changed

methods.reload = function() {
var $select = $(this);
var data = $select.data('dropkick');
$select.removeData("dropkick");
$("#dk_container_"+ data.id).remove();
$select.dropkick(data.settings);
};
सही dropkick में निम्नलिखित स्निपेट के बाद ऊपर कोड जोड़ें:

* - 2012-05-25 godboutj, keep default tabindex 0
* - 2012-08-09 godboutj, add optgroup class option with the data-dkgroupclass attribute on optgroup element
* - 2012-08-15 godboutj, fix forceSyncWithSelect method if value appear multiple of time, take the first occurrence only
* - 2012-09-07 godboutj, toggle on click on the menu selection
