bootstrap - align multiple buttons with large textbox using full container space - html

Question

I am trying to have a textbox in bootstrap, which has the same look and feel as the one you place inside a panel (large, rounded corners, full div length). On the right side of such a textbox I want to have a few buttons.
I tried a bunch of stuff - either it becomes correctly aligned, but the textbox loses all styles. Or the textbox looks correct, but the buttons wrap down to next line!
Some of what I have tried:
<div class="row">
<div class='col-md-8'>
<input type="text" class="input-block-level input-lg" placeholder="Stuff 2">
<button type="submit" class="btn">Save</button>
<button type="submit" class="btn">Delete</button>
</div>
</div>
and...
<div class="input-group">
<input type="text" class="form-control" placeholder="Stuff 2">
<span class="input-group-btn">
<button class="btn btn-default" type="button">Go!</button>
</span>
</div>
and...
<div class="form-horizontal">
<input type="text"/>
<button class="btn">Sign up</button>
</div>
Nothing works!I am thinking it shouldnt be so hard to place a bunch buttons next to a textbox that takes all available space and is nice and large :(
Any help is very much appreciated

Answer 1

Couldn't you just do it like this?
<div class="form-group">
<div class="col-md-9">
<input type="text" class="form-control" placeholder="Stuff2" />
</div>
<div class="col-md-3">
<button class="btn btn-primary">Save</button> <button class="btn btn-danger">Delete</button>
</div>
</div>

Answer 2

As far as I know that to combine textbox and button, I use:
class="input-group"
and give class="form-control" to all textboxes
You mean like this follows:
<div class="row">
<div class='col-md-8'>
<div class="input-group">
<input type="text" class="form-control" placeholder="Stuff 2">
<span class="input-group-btn">
<button type="submit" class="btn">Save</button>
<button type="submit" class="btn">Delete</button>
</span>
</div>
<div class="input-group">
<input type="text" class="form-control" placeholder="Stuff 2">
<span class="input-group-btn">
<button class="btn btn-default" type="button">Go!</button>
</span>
</div>
<div class="form-horizontal">
<div class="input-group">
<input type="text" class="form-control">
<span class="input-group-btn">
<button class="btn">Sign up</button>
</span>
</div>
</div>
</div>
