Note: Below is the original page from the Bootlint documentation, some of the info here might not apply to Bootlint-NG!
As mentioned in the documentation, Bootstrap does not support two or more add-ons either side (left or right) of an input group.
Right (two add-ons are fine so long as they're on different sides):
<div class="input-group">
<span class="input-group-addon">$</span>
<input type="text" class="form-control">
<span class="input-group-addon">.00</span>
</div>
Wrong:
<div class="input-group">
<span class="input-group-addon">USD</span>
<span class="input-group-addon">$</span>
<input type="text" class="form-control">
</div>
Wrong:
<div class="input-group">
<input type="text" class="form-control">
<span class="input-group-addon">.00</span>
<span class="input-group-addon">USD</span>
</div>
