Select List with the width of the form in Bootstrap - css

Question

I'm doing an application with Rails and AngularJS which have a form with a select list, the problem it's that it looks pretty ugly, because the width is too large for the options it have.
Here's my form with some sample values
How can I shorten the width of the select list without distorting the rest of the form?
Here's the code of my form
<h1>Create Form</h1>
<form ng-submit="addPoll()" style="margin-top:30px;">
<div class="form-group">
<label>Title</label>
<input type="text" class="form-control" ng-model="title"></input>
</div>
<div class="form-group">
<label>Description</label>
<textarea type="text" class="form-control" ng-model="description"></textarea>
</div>
<div class="form-group">
<label>Group</label>
<select class="form-control" ng-model="data.groupSelect">
<option ng-repeat="group in data.groups" value="{{group.id}}" >{{group.name}}</option>
</select>
</div>
<div class="form-group">
<label>Welcome Message</label>
<textarea type="text" class="form-control" ng-model="initial_message"></textarea>
</div>
<div class="form-group">
<label>Outgoing Message</label>
<textarea type="text" class="form-control" ng-model="final_message"></textarea>
</div>
<div class="checkbox">
<label>
<input type="checkbox" ng-model="allow_anonymous_answer"> Allow Anonymous Answer
</label>
</div>
<button type="submit" class="btn btn-primary" style="float: right;">Continue</button>
</form>

Answer 1

You can do it a few different ways. You can either add an inline style to the div.form-group or use Bootstrap's grid system. Here's two examples:
<div class="form-group" , style="width: 200px">
<label>Group</label>
<select class="form-control" ng-model="data.groupSelect">
<option ng-repeat="group in data.groups" value="{{group.id}}">{{group.name}}</option>
</select>
</div>
<div class="row">
<div class="col-sm-3">
<div class="form-group">
<label>Group</label>
<select class="form-control" ng-model="data.groupSelect">
<option ng-repeat="group in data.groups" value="{{group.id}}">{{group.name}}</option>
</select>
</div>
</div>
</div>
