Semantic UI dropdown multi-select removes value on refresh

Question

I'm using ajax to bind partial view in a div#demo and initiating dropdown on ajaxstop .

After submitting the details, ajax loads partial view again to refresh the table section, and then re-initiating dropdown on ajaxstop .

this works fine for single selection dropdown, but multi-select dropdown reset the selected value.

I don't want multi-select dropdown to reset it's value.

 // partial views var viewA = ` <select class="ui dropdown"> <option value="">Select Single Car</option> <option value="volvo">Volvo</option> <option value="saab">Saab</option> <option value="mercedes">Mercedes</option> <option value="audi">Audi</option> </select> <select class="ui dropdown" Multiple> <option value="">Select Multiple Car</option> <option value="volvo">Volvo</option> <option value="saab">Saab</option> <option value="mercedes">Mercedes</option> <option value="audi">Audi</option> </select> <button type="button" class="ui button primary">Submit</button> ` var viewB = `<table class="ui celled table unstackable"> <thead> <tr><th>Name</th> <th>Age</th> <th>Job</th> </tr></thead> <tbody> <tr> <td data-label="Name">James</td> <td data-label="Age">24</td> <td data-label="Job">Engineer</td> </tr> <tr> <td data-label="Name">Jill</td> <td data-label="Age">26</td> <td data-label="Job">Engineer</td> </tr> <tr> <td data-label="Name">Elyse</td> <td data-label="Age">24</td> <td data-label="Job">Designer</td> </tr> </tbody> </table>` $(document).ajaxStop(function() { $(".dropdown").dropdown({ useLabels: false, }); }); function bindViewA() { $.ajax({ url: "https://jsonplaceholder.typicode.com/todos/1" }); $("#viewA").html(viewA); } function bindViewB() { $.ajax({ url: "https://jsonplaceholder.typicode.com/todos/1" }); $("#viewB").html(viewB); } $(document).on('click', 'button', () => { bindViewB(); }); bindViewA(); bindViewB();

 #demo { padding: 30px; } #viewA { margin-bottom: 10px; }

You can set the dropdown without initialize using setting like below

$(".dropdown").dropdown('setting', {
    useLabels: false,`
})'

 // partial views var viewA = ` <select class="ui dropdown"> <option value="">Select Single Car</option> <option value="volvo">Volvo</option> <option value="saab">Saab</option> <option value="mercedes">Mercedes</option> <option value="audi">Audi</option> </select> <select class="ui dropdown" Multiple> <option value="">Select Multiple Car</option> <option value="volvo">Volvo</option> <option value="saab">Saab</option> <option value="mercedes">Mercedes</option> <option value="audi">Audi</option> </select> <button type="button" class="ui button primary">Submit</button> ` var viewB = `<table class="ui celled table unstackable"> <thead> <tr><th>Name</th> <th>Age</th> <th>Job</th> </tr></thead> <tbody> <tr> <td data-label="Name">James</td> <td data-label="Age">24</td> <td data-label="Job">Engineer</td> </tr> <tr> <td data-label="Name">Jill</td> <td data-label="Age">26</td> <td data-label="Job">Engineer</td> </tr> <tr> <td data-label="Name">Elyse</td> <td data-label="Age">24</td> <td data-label="Job">Designer</td> </tr> </tbody> </table>` $(document).ajaxStop(function() { $(".dropdown").dropdown('setting', { useLabels: false, forceSelection: false, sortSelect: true, //clearable: true, fullTextSearch: true, onHide: function() { //cleanDdlOnHide(this); } }); }); function bindViewA() { $.ajax({ url: "https://jsonplaceholder.typicode.com/todos/1" }); $("#viewA").html(viewA); } function bindViewB() { $.ajax({ url: "https://jsonplaceholder.typicode.com/todos/1" }); $("#viewB").html(viewB); } $(document).on('click', 'button', () => { bindViewB(); }); bindViewA(); bindViewB();

 #demo { padding: 30px; } #viewA { margin-bottom: 10px; }

This seems to be fixed in the community fork https://fomantic-ui.com

So try to change the css + js accordingly

<link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/fomantic-ui@2.8.3/dist/semantic.min.css">
<script src="https://cdn.jsdelivr.net/npm/fomantic-ui@2.8.3/dist/semantic.min.js"></script>

I prepared a working jsfiddle using your code here https://jsfiddle.net/sezL041k/

I have not found the expected behavior of the dropdown function in semantic . However, you can make do with a little patch on the ajaxStop function:

$(document).ajaxStop(function() {
  var psel = [];
  $(".dropdown [multiple]").each(function(){
    psel.push($(this).val());
  });
  $(".dropdown").dropdown({
    useLabels: false
  });
  $(".dropdown [multiple]").each(function(){
    $(this).val(psel[0]).trigger('change');
    psel.shift();
  });
});

This should work even if there are several multiple dropdowns, as long as they are always selected by jquery in the same order. If not, you can always make psel a hash and give each multiple selector an id .
