Apologizes if this seems like a basic question. No finding a good example to copy. Is there a way to place an input and button(s) in the same field? In this example the buttons wrap to the next line. Is there a class I'm not finding? I'm aware of the action class. But this isn't what I need.
<div class="required field">
<label>Resource</label>
<div class="ui input">
<input type="text">
<div class="ui button">
Btn1
</div>
<div class="ui button">
Btn2
</div>
</div>
</div>

When I put this in a grid things don't line up. As the buttons top align with the label.

You could do something like this: http://jsfiddle.net/6Lpj5udz/1/
First is sort of a hack but it works.
The second is just using the fact that you can attach a button to an input, only it will skew the width of the button the larger the form gets, but both are acceptable ways to accomplish what you need.
Good luck!
Thanks @ph7vc ! This is something that I'd think is very common.
This sort of works too. Wonder it this is a supposed to align properly?
<div class="inline fields">
<div class="field">
<label>Last name</label>
<input type="text" placeholder="Full Name">
</div>
<div class="field">
<div class="ui blue button">Test</div>
</div>
</div>

That looks like a similar issue to #1536. For some reason I remember seeing this issue already reported somewhere else, but I can't seem to find it
In any case, it does the same in my browsers. It hardly noticeable imo and probably not a high priority fix. It looks like it is off by a single pixel

Not sure if someone will see this but I found another solution by mistake :+1:
Puedes hacer algo como esto:
<div class="fields">
<div class="field">
<label> < 65 </label>
<input type="number" name="edad_1" id="edad_1" min="0">
</div>
<div class="field">
<label> 66 a 84 </label>
<input type="number" name="edad_2" id="edad_2" min="0">
</div>
</div>
<div class="field">
<label for=""> </label>
<button class="ui button blue fluid">Cotizar</button>
</div>

The use of a non breaking space as a label
<label for=""> </label>
is a neat, simple solution to the OP.
