bootstrap radio button text group - html

Question

I would like to group the radio button and bootstrap select but they're not inline.
<div class="container">
<form class="form-inline">
<div class="input-group">
<label class="radio-inline">
<input name="radioGroup" id="radio1" value="option1" type="radio"><span class="input-group-addon"> Preset Size (<b>inch</b>):
</span></label>
<div class="col-md-6">
<select id="size" class="selectpicker form-control" data-live-search="true" title="Please select preset size ...">
<option>36” x 84”</option>
<option>48”x84”</option>
<option>60”x84”</option>
<option>72x84”</option>
<option>48”x96”</option>
</select>
</div>
</div> <!-- Radio + Dropdown -->
</form>
</div> <!-- container -->
and I also want to group 2 text boxes together with the label to create user input.
<div class="container">
<form class="form-inline">
<div class="input-group">
<label class="radio-inline">
<input name="radioGroup" id="radio2" value="option2" checked="" type="radio"> Custom Size:
</label>
<div class="col-sm-4">
<input type="text" class="form-control" id="customSize1" placeholder="">
</div>
<div class="col-sm-4">
<label> x </label>
</div>
<div class="col-sm-4">
<input type="text" class="form-control" id="customSize2" placeholder="">
</div>
</div>
</form>
</div>
Here's the output screenshot.

Answer 1

You may need to re-arrange your code a bit to fit bootstrap's use.
Firstly, use .form-group - also put element in rows when possible.
Something along the lines of:
ps you may have to adjust this a bit but it should give you a good place to start from
.form-inline input.form-control {
width: 100%;
}

<div class="col-xs-3">

</div>

</div>

Answer 2

You forgot the row div. whenever you are using bootstrap layout with columns- you need to nest the columns div inside a row div:
<div class="row">
<div class="col-sm-4"> first third</div>
<div class="col-sm-4"> second third</div>
<div class="col-sm-4"> third third</div>
</div>
Read the bootstrap doc for more information

Answer 3

Here are two ways you can do this depending on if you want all the elements in one row or not. It's just utilizing input-groups and not much else.
