Fluid Widths
To use a fluid layout (this assumes you're using Boostrap 3.x), simply change the options classes to incorporate bootstrap's row-fluid
class
<script>
$(document).ready(function(){
$("#mycanvas").gridmanager({
controlPrepend: "<div class='row-fluid'><div class='col-md-12'><div id='gm-addnew' class='btn-group '>",
rowClass: "row-fluid",
rowSelector: "div.row-fluid",
rowPrepend: "<div class='row-fluid gm-editing'>"
}
);
});
</script>
