  <p>( I am sorry for the poor identation, but i posted a link to bootply also). I want the inputs of the first form to appear two at each row, so it must look like this for form 1</p>
  
  <pre><code>Input1 input2 
  input3 input4
  </code></pre>
  
  <p>and </p>
  
  <pre><code>Input5 Input6
  Input7 Input8
  </code></pre>
  
  <p>for form 2 in the second collumn. I set up two collumns both of them using col-md-6 class and in each collumn i am placing the fields. But even with setting two sub collumns of 3 I can't get the result I want. What am i doing wrong? I am using bootstrap 3</p>
