Bootstrap 3 - How to maximize input width inside navbar

Solution 1:

For Bootstrap version 3.2 and up you should also set the display:table; for the input-group and set the width to 1% for the input-group-addon.

<div style="display:table;" class="input-group">
            <span style="width: 1%;" class="input-group-addon"><span class="glyphicon glyphicon-search"></span></span>
            <input type="text" autofocus="autofocus" autocomplete="off" placeholder="Search Here" name="search" style="" class="form-control">
          </div>

If you allow changing the position of your navbar elements? I don't understand "without creating line-breaks (i.e., that the "Clear" link will be tight with the "About" link)." Try this: http://bootply.com/78374.

What i did:

• Drop the float left of the form (by dropping the navbar-left class)
• Give other navbar elements a right float (the navbar-right class)
• Set display of the form-group to inline (style="display:inline")
• Change the position of the elements (the right floated first)

• Expand div to max width when float:left is set
