title: gridstack.js - how to strech columns to fit width?
body: <p>I'm trying to use gridstack ( <a href="https://github.com/troolee/gridstack.js" rel="nofollow">https://github.com/troolee/gridstack.js</a> ) in a configuration of just 5 columns, but the problem is the default is 12 columns, and when I configure to only 5, these 5 columns are squeezed to the left and I have the space of 7 unusable columns on the right.</p>
  
  <p>I would like to use all the screen width to acomodate these columns. Could you help me with the solution? I used <code>options = { width: 5 }</code> and the recommendations on <a href="https://github.com/troolee/gridstack.js#change-grid-width" rel="nofollow">https://github.com/troolee/gridstack.js#change-grid-width</a> , but with no success.</p>
  
  <p>Thank you!</p>
