input-group-addon with bootstrap-select

I tried to use Label 2 with bootstrap-select, but it looks different to the bootstrap (Label 1) one. How is it possible to get the two labels in the code below look the same?

From Bootstrap docs:

Extend form controls by adding text or buttons before, after, or on both sides of any text-based <input>. Use .input-group with an .input-group-addon or .input-group-btn to prepend or append elements to a single .form-control.

You need to wrap the select and .input-group-addon in a .input-group:

<div class="input-group">
  <span class="input-group-addon">Label 2</span>
  <select id="lunch" class="selectpicker form-control" data-live-search="true" title="Please select a lunch ...">
    <option>Hot Dog, Fries and a Soda</option>
    <option>Burger, Shake and a Smile</option>
    <option>Sugar, Spice and all things nice</option>
    <option>Baby Back Ribs</option>
    <option>A really really long option made to illustrate an issue with the live search in an inline form</option>
  </select>
</div>

I've modified caeth's solution with additional CSS to ensure the select button is rounded at their respective corners.

HTML

<form class="form-inline">
    <div class="input-group">
        <span class="input-group-addon">Label</span>
        <select id="lunch" class="selectpicker form-control" data-live-search="true" title="Please select a lunch ...">
            <option>Hot Dog, Fries, and a Soda</option>
            <option>Burger, Shake, and a Smile</option>
            <option>Sugar, Spice, and all things nice</option>
            <option>Baby Back Ribs</option>
            <option>A really really long option made to illustrate an issue with the live search in an inline form</option>
        </select>
    </div>
</form>

CSS

.input-group > .input-group-btn:last-child > .selectpicker {
    border-top-right-radius: 5px;
    border-bottom-right-radius: 5px;
}

.input-group > .input-group-btn:first-child > .selectpicker {
    border-top-left-radius: 5px;
    border-bottom-left-radius: 5px;
}

I've just found an easy way to include add-ons with select (no bootstrap-select). This answer might not be strictly related to the bootstrap-select question, but might be helpful for someone landing here looking for this answer (as I did). I just move the select under the add-on, with margin:-4px, and add 4 pixels to the width like this

.input-group select.form-control {
    margin-left: -4px;
    width: calc(100% + 4px);
}

and then I set a relative position and z-index to the add-on, like this:

.input-group .input-group-addon {
    z-index: 5;
    position: relative;
}

I hope this helps
