Select the same value multiple times from a dual listbox

Question

Can I use bootstrapDualListbox() to create an input that allows selecting the same value multiple times. I've been looking for a way to this, but didn't found. Assuming I have a list

<select multiple>
<option value="1"> One </option>
<option value="2"> Two</option>
<option value="3"> Three</option>
</select>

How to get an input that allows selecting this kind of multiple items: 1,1,2,3,3?

I've tried to find a way to use bootstrap dual listbox plugin, but I can only select one item one time. I'm expecting to select one item multiple times if I want to.

You can add a multiple attribute to your <select> so you can multi-select by holding CMD or Ctrl key

 <select multiple> <option value="1"> One </option> <option value="2"> Two</option> <option value="3"> Three</option> </select>
