How to place two input-group side by side in boostrap form

Question

I am trying to achieve a form layout where two form-group elements are side by side on a single line. I have tried styling with the following properties; display:inline, display:flex, etc however none of these have worked.

Here's a snippet of the form-group elements that I want to be side by side:

<div class="form-group">
    <label for="entercomments" class="col-sm-2 control-label">From Date</label>
    <div class="col-sm-10">
        <div class="input-group fromdate inline"  data-date-format="yyyy-mm-dd" style="width:250px">
            <input type="text" class="form-control fromdate"  placeholder="dd-mmm-yyyy" id="FromDate" runat="server" data-date-container="#formDiv" />
            <div class="input-group-addon"><span class="glyphicon glyphicon-calendar"></span></div>
        </div>
    </div>
</div>
<div class="form-group">
    <label for="entercomments" class="col-sm-2 control-label">To Date</label>
    <div class="col-sm-10">
        <div class="input-group todate inline" data-date-format="yyyy-mm-dd" style="width:250px">
            <input type="text" class="form-control todate" placeholder="dd-mmm-yyyy" id="ToDate" runat="server" data-date-container="#formDiv"  />
            <div class="input-group-addon"><span class="glyphicon glyphicon-calendar"></span></div>
        </div>
    </div>
</div>

Answer 1

Seeing that you're using Bootstrap, you could use bootstraps grid system here to achieve that required layout:

<div class="row">
  <div class="col">
    <div class="form-group">
      <!-- Existing form group markup -->
    </div>
  </div>
  <div class="col">
    <div class="form-group">
      <!-- Existing form group markup -->
    </div>
  </div>
</div>

The idea here is to enclose the "form-group" elements that you want to align on the same row, within a "column" (ie <div class="col">). Each column is then enclosed in a common "row" (ie <div class="row">) and, by default, this will cause each column to share half the width of the row.
