Issue when aligning the drop down boxes using bootstrap - css

Question

I am using bootstrap in my application. I am having a form which contains multiple drop down boxes which are placed inline. The width of the container containing the form is col-lg-12 and is taking the entire screen. Because of the data inside the drop down the last two drop downs are displayed in the second line. I tried giving the max-width property of the select box to 50%. The drop down width reduces but the margin still remains the same. I am not goot at bootstrap. Please let me know where I am going wrong. I am posting the code below:
<form novalidate role="form" name="filterForm" class="form-inline">
<div ng-repeat="criteria in criterias">
<div class="m-b">
<div class="form-group s-b">
<span>Country</span>
<select class="form-control" ng-options="item for item in country" name="country" ng-model="classification.country">
</select>
</div>
<div class="form-group s-b">
<span>State</span>
<select ng-options="item for item in state" class="form-control" name="state" ng-model="criteria.state" style="max-width:50%">
</select>
</div>
<div class="form-group s-b">
<span>City</span>
<select class="form-control" ng-options="item for item in Cities" name="account" ng-model="criteria.city" style="max-width:50%;">
</select>
</div>
<div class="form-group s-b">
<span>Predicate</span>
<select class="form-control" name="account" ng-model="criteria.predicate">
<option value="matches">Matches</option>
<option value="not-matches">Not Matches</option>
</select>
</div>
<div class="form-group s-b">
<span>Value</span>
<select class="form-control" name="account" ng-model="criteria.value" style="min-width:100px;">
</select>
</div>
<div class="form-group">
<span>
<button class="btn btn-sm btn-primary pad-btn" type="submit" ng-click="addCriteria()"><i class="fa fa-plus"></i>
</button>
<button class="btn btn-sm btn-danger pad-btn" type="submit" ng-click="deleteCriteria(criteria)"><i
class="fa fa-minus"></i></button>
</span>
</div>
</div>
</div>
<button class="btn btn-sm btn-primary pad-btn align-center" type="submit" ng-click="searchParams(filterForm)">Submit
<i class="fa fa-check"></i></button>
<button class="btn btn-sm btn-warning pad-btn align-center" type="submit" ng-click="resetFilter()">Reset
<i class="fa fa-reply"></i></button>
</form>

Answer 1

Try adding a class
Since your data is too big you should try adding a class that modifies the position of the dropdowns, since they are absolute they should be easy to move around to where you want.
Explanation of bootsraps column system
If you set your class col-xs-12 it will be bull width all the way from mobile to big desktop
If you set your class to col-xs-12 col-lg-6 then xs, sm and md will all be full width but lg will be half width.
try using shoe lace to model your column setup.
Note
You should check out ui.bootstrap since you're using angular.js. It removed the use of jQuery so you don't run into any compatibility issues or strange bugs.
