Bootstrap-Select width in form

I'm using Bootstrap v4 and bootstrap-select js/css (in ASP.NET MVC project) and I have a problem in my form. The select with multiple options from bootstrap-select is wider than the rest of my inputs, even though it's in a div with class="form-control". The output looks something like this: enter image description here

As you can see, the Field Of Expertise dropdown is way larger then the rest of the inputs. I tried to edit bootstrap-select.css and change width:auto, but didn't work. Is there anything I can do to match the width of my other inputs?

My code looks something like this

<div class="form-group">
    @Html.LabelFor(v => v.BirthDate)
    @Html.TextBoxFor(v => v.BirthDate, "{0:yyyy-MM-dd}", new { @class = "form-control", type = "date" })
    @Html.ValidationMessageFor(v => v.BirthDate)
</div>
<div class="form-group">
    @Html.LabelFor(v => v.ResidenceCountry)
    @Html.TextBoxFor(v => v.ResidenceCountry, new { @class = "form-control" })
    @Html.ValidationMessageFor(v => v.ResidenceCountry)
</div>
<div class="form-group">
    @Html.LabelFor(m => m.CurrencyId)
    @Html.DropDownListFor(m => m.CurrencyId, new SelectList(Model.Currencies, "Id", "Name"), "", new { @class = "form-control" })
    @Html.ValidationMessageFor(m => m.CurrencyId)
</div>
<div class="form-group">
    @Html.LabelFor(m => m.FieldOfExpertiseIds)
    @Html.ListBoxFor(m => m.FieldOfExpertiseIds, new MultiSelectList(Model.FieldOfExpertises, "Id", "Name"), new { @class = "selectpicker form-control", @data_selected_text_format = "count > 2", @data_size = "6" })
    @Html.ValidationMessageFor(m => m.FieldOfExpertiseIds)
</div>

UPDATE:

I changed now the form-group to something like this (added @data_width = "auto"):

<div class="form-group">
    @Html.LabelFor(m => m.FieldOfExpertiseIds)
    <br />
    @Html.ListBoxFor(m => m.FieldOfExpertiseIds, new MultiSelectList(Model.FieldOfExpertises, "Id", "Name"), new { @class = "selectpicker form-control", @data_selected_text_format = "count > 2", @data_size = "6" , @data_width="auto" })
    @Html.ValidationMessageFor(m => m.FieldOfExpertiseIds)
</div>

And now it looks a little bit better, but still a problem: enter image description here

Solution

  • I was able to get it to work once I straightened out some external dependencies. One thing to pay attention to is the versions required. JQuery 1.8.0+ and bootstrap version 4 didn't work for me. I was able to get it to work with 3.3.6.
