Semantic-UI Multiple selection get values
Suggesting that your code looks like this:
<div class="ui multiple selection dropdown">
<i class="dropdown icon"></i>
<div class="default text">Tag Multiple Categories</div>
<select multiple="" id="multi-select">
<option value="">Categories</option>
<option value="datastructure">Data Structure</option>
<option value="stack">Stack</option>
<option value="queue">Queue</option>
</select>
</div>
</div>
the following will return an array of selected values:
$("#multi-select").dropdown("get value")
Output:
["stack", "queue"]
Note:
Make sure not to have hidden input field in the html otherwise it returns a string value instead of array of values
