I'm currently working on a webpage that uses Bootstrap. It has a form with a label and text input field.
When I add the class="custom-control-input" to the input field, Bootstrap hides it. Can someone explain why?
If I don't include the class, the input field appears but doesn't extend to the full width of its parent div tag.
Here is the code snippet:
<div class="container">
<form class="needs-validation" novalidate action="submit_transgene_entry.php" method="post">
<div class="row">
<div class="col-md-2 mb-3">
<label for="comments_fieldID1">This field is displayed but not full width</label>
</div>
<div class="col-md-10 mb-3">
<input type="text" id="comments_fieldID1" name="comments_fieldName">
</div>
</div>
<div class="row">
<div class="col-md-2 mb-3">
<label for="comments_fieldID2">The next field is hidden by custom-control-input</label>
</div>
<div class="col-md-4 mb-3">
<input type="text" id="comments_fieldID2" class="custom-control-input" name="comments_fieldName">
</div>
</div>
<div class="row">
<div class="col-md-3 mb-3">
<input type="submit" name='accept_transgene_entry' class="btn btn-primary btn-lg btn-block" value="Accept Transgene Entry" alt="Accept Transgene Entry"/>
</div>
</div>
</form>
</div>
