results: function() {}

On that code, when I click #open_input , ul.dropdown-menu.bigul 's width changes from 160px to 182px. As you can see on , If I click #open_input some <li> is added.
Even I gave style="100%" to all elements of var ul_text , it does not works.
Question:
First Question : How can I make width will be the same as initial status? I want it to have the same width - 160px. It's main question.
Second Question : If it is possible, I want to follow width of <button class="btn btn-primary dropdown-toggle" type="button" data-toggle="dropdown">Dropdown Example button . In other words, if width of button is 20px, dropdown-menu and other following <li> 's width will be 20px width also. But first question is most important to me. Second question is not as important as first one.

you can use .one method:
$('#open_input').one('click', function(e) {
$('.bigul').append(ul_text);

The simple solution, modify this line in your javascript:
<input type="text" class="form-control" id="tags" placeholder="Enter email">
to
<input type="text" class="form-control" id="tags" placeholder="Enter email" style="width:158px;">
